Codebase sync

Send as webhook.me.uk, add favicon, share image and SEO tags
Mail now comes from no-reply@webhook.me.uk (DKIM, SPF and DMARC are set up for it) and the Message-ID uses that domain instead of the container hostname. The landing page gets a favicon, an Open Graph image, canonical/OG/Twitter/JSON-LD tags, robots.txt that keeps crawlers off email URLs, and a sitemap. Footer links to dixon.cx.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by

+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.

+# Webhook Parser Development Guide
+
+This guide explains how to create custom webhook parsers for the Webhook Email Forwarder.
+
+## 📋 Overview
+
+Parsers format webhook data from specific services (GitHub, Grafana, Stripe, GitLab, etc.) into readable HTML emails instead of the raw request dump.
+
+## 🚀 Quick Start
+
+### URL Format
+
+Parsers are triggered by adding the parser name to the URL:
+
+```
+https://your-domain.com/{email}/{parser-name}
+```
+
+**Examples:**
+- `https://webhook.me.uk/test%40example.com/github`
+- `https://webhook.me.uk/user%40company.com/grafana`
+- `https://webhook.me.uk/dev%40startup.io/json`
+
+### How It Works
+
+1. User configures the webhook URL with their email and parser name
+2. Service sends a webhook to that URL
+3. The server looks the parser name up in the `parsers` map in `main.go`
+4. The parser turns the request into an email body and subject
+5. The email is sent and the caller gets a JSON acknowledgement naming the parser and subject
+
+If no parser is named, the name is unknown, or the parser returns `ok == false`, the default raw-request email is used instead.
+
+---
+
+## 🛠️ Creating a Parser
+
+### File and Function
+
+Create `parser_{servicename}.go` in the package root with one function of this type:
+
+```go
+// Parser turns a raw webhook into an email. ok=false means "fall back to the default email".
+type Parser func(raw []byte, headers http.Header, meta Meta) (html, subject string, ok bool)
+```
+
+Then register it in `main.go`:
+
+```go
+var parsers = map[string]Parser{
+    "github":      githubParse,
+    "grafana":     grafanaParse,
+    "json":        jsonParse,
+    "wxinteract":  wxinteractParse,
+    "servicename": servicenameParse,   // <- add yours
+}
+```
+
+### Parameters
+
+#### `raw []byte`
+The complete request body as received.
+
+```go
+v, err := decodeJSON(raw)          // ordered JSON: *OMap, []any, string, json.Number, bool, nil
+payload := asObject(v)             // nil if the body is not an object
+```
+
+`decodeJSON` keeps object keys in the order the sender wrote them, so tables read naturally. Use it rather than `encoding/json` into a `map`, which sorts keys.
+
+#### `headers http.Header`
+All request headers, including `Host`. Lookups through `headers.Get` are case-insensitive, which covers the lowercase names HTTP/2 delivers:
+
+```go
+event := headers.Get("X-GitHub-Event")
+```
+
+#### `meta Meta`
+```go
+type Meta struct {
+    Date        string // "2026-01-22 15:30:45"
+    IP          string // the client address nginx forwards, not the proxy
+    Method      string // "POST"
+    ContentType string // "application/json"
+}
+```
+
+### Return Value
+
+- **Success:** the complete HTML document (from `emailShell`), the subject line, and `true`
+- **Failure:** `"", "", false` to fall back to the default email
+
+---
+
+## 🎨 Building the Email
+
+Never write a full HTML document by hand. Compose the body from the helpers in `render.go` and wrap it with `emailShell`, which adds the stylesheet, gradient header, and footer. Every parser looks the same this way and design changes happen in one place.
+
+```go
+html := emailShell(title, stamp, body, footerSentence)
+```
+
+| Argument | What it is |
+|----------|------------|
+| `title` | Header text, already HTML-safe. Start with an emoji. |
+| `stamp` | Usually `h(meta.Date)`. Shown as a pill under the title. |
+| `body` | Your sections. |
+| `footerSentence` | One line, e.g. "This Stripe webhook was automatically forwarded to your email address." Empty string for the generic default. |
+
+### Building Blocks
+
+```go
+section(title, innerHTML string) string   // <div class="section"> with a title
+table(rows ...string) string              // a real <table class="metadata">
+row(label, valueHTML string) string       // one label/value <tr>
+link(url string) string                   // escaped <a href>
+kvTable(m *OMap) string                   // every key/value of an object as one table
+renderDataAsTable(v any, depth int) string // arbitrary nested JSON as tables (generic fallback)
+```
+
+Example:
+
+```go
+body := section("💳 Payment Details", table(
+    row("Event", h(event)),
+    row("Amount", h(amount)+" "+h(currency)),
+    row("Customer", h(customer)),
+)) + section("📝 Note", `<div class="message-box">`+esc(note)+`</div>`)
+```
+
+**Other classes you can use inside a section:**
+
+| Class | Use for |
+|-------|---------|
+| `.subsection-title` | A bold sub-heading |
+| `.data-box` | A `<pre>` for raw JSON, headers, or code (dark block) |
+| `.message-box` | Quoted free text such as an SMS body |
+| `.error-box` | Error details |
+| `.array-item` / `.array-item-title` | A card for one item of a list (an alert, a commit) |
+| `.path-title` | A breadcrumb pill above a nested table, e.g. `order->items->[0]` |
+| `.commit-item` with `.sha`, `.who`, `.msg` | The GitHub commit card, reusable for any id + author + message list |
+
+### Reading values
+
+```go
+str(v)                       // scalar as text ("" for null, "true"/"false" for bools)
+strOr(v, "N/A")              // PHP's `?? 'N/A'`: only missing/null takes the default
+get(payload, "repository", "full_name")   // nested lookup, nil if any step is missing
+asObject(v)                  // *OMap or nil
+isContainer(v)               // object or array?
+num(v)                       // float64 for a json.Number, else 0
+```
+
+### Escaping
+
+Two helpers, use the right one:
+
+- `h(s)` for anything that goes into an attribute or a single-line value.
+- `esc(s)` for free text that may contain line breaks (commit messages, descriptions, SMS bodies). It escapes **and** converts newlines to `<br>`.
+
+Subjects are plain text, never escaped.
+
+---
+
+## 📝 Example: Simple Parser
+
+`parser_simplepay.go` for a fictional "SimplePay" service:
+
+```go
+package main
+
+import "net/http"
+
+func simplepayParse(raw []byte, headers http.Header, meta Meta) (string, string, bool) {
+	payload := asObject(mustDecode(raw))
+	if payload == nil {
+		return "", "", false // not a JSON object: use the default email
+	}
+
+	event := strOr(payload.Get("event"), "Unknown")
+	amount := strOr(payload.Get("amount"), "N/A")
+	currency := strOr(payload.Get("currency"), "USD")
+	customer := strOr(payload.Get("customer_email"), "Unknown")
+	note := strOr(payload.Get("note"), "")
+
+	body := section("💳 Payment Details", table(
+		row("Event", h(event)),
+		row("Amount", h(amount)+" "+h(currency)),
+		row("Customer", h(customer)),
+		row("IP Address", h(meta.IP)),
+	))
+	if note != "" {
+		body += section("📝 Note", `<div class="message-box">`+esc(note)+`</div>`)
+	}
+
+	html := emailShell("💳 SimplePay: "+h(event), h(meta.Date), body,
+		"This SimplePay webhook was automatically forwarded to your email address.")
+	return html, "💳 SimplePay " + event + " - " + amount + " " + currency, true
+}
+
+func mustDecode(raw []byte) any {
+	v, err := decodeJSON(raw)
+	if err != nil {
+		return nil
+	}
+	return v
+}
+```
+
+---
+
+## 🎨 Style Guidelines
+
+The shell owns colours, fonts, and spacing. Parsers only choose structure and words.
+
+1. **Sections**: one `section` per logical group
+2. **Tables**: `table(row(...))` for label/value pairs, never hand-written divs
+3. **Lists**: one `.array-item` card per item (alerts, commits, line items)
+4. **Raw data**: `.data-box` for anything the reader might want to copy
+5. **Free text**: `.message-box`, escaped with `esc`
+6. **Links**: `link(url)`
+
+### Emojis
+
+- 💳 Payment events
+- 🚀 Deployments/releases
+- 📤 Push/upload events
+- 🔀 Merge/pull request events
+- ⚠️ Errors/warnings
+- ✅ Success events
+- 🔔 Notifications
+
+Put the same emoji at the start of the subject line so inbox filters can key on it.
+
+---
+
+## 🔒 Security Best Practices
+
+### 1. Escape everything dynamic
+
+```go
+// ❌ DANGEROUS - XSS in the email
+body += "<div>" + str(payload.Get("user_input")) + "</div>"
+
+// ✅ SAFE (single line)
+body += "<div>" + h(str(payload.Get("user_input"))) + "</div>"
+
+// ✅ SAFE (multi-line free text)
+body += `<div class="message-box">` + esc(str(payload.Get("message"))) + `</div>`
+```
+
+### 2. Validate input
+
+```go
+if payload == nil || payload.Get("event_type") == nil {
+    return "", "", false
+}
+```
+
+### 3. Verify signatures (optional)
+
+```go
+sig := headers.Get("X-Service-Signature")
+mac := hmac.New(sha256.New, []byte(secret))
+mac.Write(raw)
+if sig == "" || !hmac.Equal([]byte(sig), []byte(hex.EncodeToString(mac.Sum(nil)))) {
+    return "", "", false
+}
+```
+
+---
+
+## 🧪 Testing Your Parser
+
+### 1. Unit test
+
+`main_test.go` has a `capture(t)` helper that swaps the mailer for an in-memory one and a `do(...)` helper that drives the handler. Add a test in the same style:
+
+```go
+func TestSimplePay(t *testing.T) {
+	c := capture(t)
+	_, out := do(t, "POST", "/t%40e.com/simplepay", `{"event":"paid","amount":"9.99"}`, nil)
+	if out["subject"] != "💳 SimplePay paid - 9.99 USD" || !strings.Contains(c.html, "9.99") {
+		t.Fatalf("%v", out["subject"])
+	}
+}
+```
+
+```bash
+go test ./...
+```
+
+### 2. Run locally without sending mail
+
+Point the server at any SMTP sink (the repo's tests don't need one, but for eyeballing the HTML):
+
+```bash
+LISTEN=127.0.0.1:8098 SMTP_ADDR=127.0.0.1:2525 go run .
+curl -X POST http://127.0.0.1:8098/test%40example.com/simplepay \
+  -H "Content-Type: application/json" \
+  -d '{"event":"paid","amount":"9.99","currency":"USD"}'
+```
+
+The JSON response tells you which parser ran and what subject was used.
+
+### 3. Test the failure case
+
+Send invalid data and confirm the response shows the default subject (`‼️ Webhook Request Received`).
+
+### 4. Test a lowercase header
+
+Real deliveries over HTTP/2 arrive with lowercase header names. `headers.Get` handles it, but if you read `headers[...]` directly you will miss them.

+## ❓ FAQ
+
+**Q: Can I use external libraries?**
+A: The project has no dependencies beyond the standard library. Keep it that way unless there is a very good reason.
+
+**Q: Can I make API calls in a parser?**
+A: Not recommended. Parsers should be fast and not depend on external services.
+
+**Q: What if my service sends different content types?**
+A: Check `meta.ContentType` and parse accordingly.
+
+**Q: Can I create multiple parsers for one service?**
+A: Yes. Register as many names as you like.
+
+**Q: Can I change the colours or fonts?**
+A: Change `shellSrc` in `render.go` and every email picks it up.

+
+## 🎨 Webhook Parsers
+
+Parsers format webhooks from specific services into beautiful, readable emails. Add the parser name to the end of the URL. If a parser can't understand the payload, the email falls back to the standard raw format so nothing is lost.
+
+### Available Parsers
+
+#### GitHub (`/github`)
+Formats GitHub webhook events with full event details.
+
+**Supported events:**
+- Push events (each commit as a card with a linked sha, author, and full multi-line message)
+- Pull requests
+- Issues
+- Releases
+- Everything else in a clean generic layout
+
+**Example URL:**
+```
+https://your-domain.com/test%40example.com/github
+```
+
+Header names are matched case-insensitively, so deliveries over HTTP/2 (where headers arrive lowercase) work correctly.
+
+#### Grafana / Prometheus Alertmanager (`/grafana`)
+Formats Alertmanager webhook payloads from Grafana or Prometheus.
+
+**What you get:**
+- Firing or resolved status in the subject and header
+- Group labels, common labels, and common annotations
+- Each alert as its own card with labels, annotations, start and end times, and a link to the generator
+
+**Example URL:**
+```
+https://your-domain.com/test%40example.com/grafana
+```
+
+#### JSON (`/json`)
+Renders any JSON body as tables. Nested objects are split into separate tables with path-based breadcrumbs (for example `order->items->[0]->tags`), so you can find a deeply nested value without squinting at raw JSON.
+
+**Handles:**
+- Objects and arrays of objects
+- Arrays of plain values, as one table under their breadcrumb
+- Scalar bodies (a bare string, number, boolean, or `null`)
+- Multi-line string values, with line breaks preserved
+
+**Example URL:**
+```
+https://your-domain.com/test%40example.com/json
+```
+
+#### Webex Interact (`/wxinteract`)
+Formats Webex Interact SMS API webhook events into clean, readable emails.
+
+**Supported events:**
+- 📤 Outbound SMS - Submitted
+- ✅ Outbound SMS - Delivered

+### Creating Your Own Parser
+
+A parser is one Go function of type `Parser` in `parser_{name}.go`, registered in the `parsers` map in `main.go`. Build the body with `section`, `table`, and `row`, escape free text with `esc`, and wrap it with `emailShell` so it picks up the shared design. See the [Parser Development Guide](PARSER_PROMPT.md) for details.

+Submitted At: 2026-01-22T16:45:00Z
+
+Message Content:
+Hello! Your appointment is confirmed for tomorrow at 2 PM.
 ```

 ## 📦 Installation

-1. Clone the repository:
+### Run the binary
+
 ```bash
 git clone https://github.com/andydixon/webhook.git
+cd webhook
+go build -o webhooks .
+LISTEN=127.0.0.1:8080 SMTP_ADDR=127.0.0.1:25 MAIL_FROM=no-reply@example.com ./webhooks
 ```

-2. Upload the files to your web server (ensure PHP is installed and configured)
+Put a reverse proxy (nginx, Caddy) in front for TLS. The service reads `X-Real-IP` / `X-Forwarded-For` from a private-address proxy to report the real client IP.

-3. Ensure the web server has permission to send emails (PHP `mail()` function)
+### Run the container

-4. Access the root URL to view the documentation page
+```bash
+docker build -t webhooks.dixon.cx:latest .
+docker run --rm -p 127.0.0.1:29593:8080 webhooks.dixon.cx:latest
+```
+
+The image is a static binary on `distroless`, runs as non-root, listens on `:8080`, and relays mail to `172.17.0.1:25` (the Docker host's SMTP server) by default. `deploy/webhooks.dixon.cx.service` is the systemd unit used in production.
+
+### Configuration
+
+| Variable | Default | Meaning |
+|----------|---------|---------|
+| `LISTEN` | `127.0.0.1:8080` | Address to listen on (`:8080` in the container) |
+| `SMTP_ADDR` | `127.0.0.1:25` | SMTP relay, no auth or TLS (`172.17.0.1:25` in the container) |
+| `MAIL_FROM` | `no-reply@webhook.me.uk` | Envelope and From address |
+| `PUBLIC_HOST` | `webhook.me.uk` | Host shown in email footers |
+
+`/healthz` returns `ok`, and `webhooks -check` exits non-zero if a running instance is unhealthy (used by the image's `HEALTHCHECK`).

 ## 🔧 Requirements

- PHP 7.0 or higher
- Web server (Apache, Nginx, etc.)
- PHP `mail()` function enabled
- Outbound SMTP/email capability
+- Go 1.24 or newer to build (no third-party dependencies), or Docker
+- An SMTP server that accepts mail from the service's address

 ## 📧 What You Receive

-Each webhook email contains:
+Every email shares one design: a gradient header with the event title and a timestamp pill, then a white card of sections. Metadata is rendered as real HTML tables so it lays out correctly in Gmail, Outlook, and Apple Mail. Code and raw payloads sit in dark code blocks.
+
+The standard (no parser) email contains:

 - **Request Timestamp**: Exact date and time when the webhook was received
 - **Request Information**: IP address, HTTP method, and Content-Type
 - **Request Headers**: All HTTP headers sent with the request
 - **Request Body**: Complete raw body content (JSON, XML, form data, etc.)
- **PHP Variables**: Parsed GET, POST, REQUEST, and FILES superglobals
+- **Parsed Variables**: GET, POST, REQUEST, and FILES superglobals as pretty-printed JSON

 ## 🔒 Security Features

 - **Email Validation**: Only valid email addresses are accepted
- **XSS Protection**: All output is sanitized using `htmlspecialchars()`
+- **XSS Protection**: All output is HTML-escaped; free-text values go through `esc`, which also preserves line breaks
 - **No Data Storage**: Webhook data is forwarded immediately and not stored
 - **Error Logging**: Failed email attempts are logged for monitoring

@@ -129,28 +372,46 @@ Each webhook email contains:
 ## 🎯 Common Use Cases

 - **Debugging**: See exactly what data third-party services are sending
+- **GitHub Notifications**: Get beautifully formatted emails for pushes, PRs, and issues
+- **Alerting**: Grafana and Prometheus alerts in your inbox without a whole notification stack
 - **Integration Testing**: Test webhook integrations before implementing full handlers
 - **Monitoring**: Monitor webhook activity and payload changes over time
 - **Documentation**: Capture real examples for API documentation
 - **Development**: Quickly test webhook flows during development
 - **Troubleshooting**: Diagnose issues with webhook payloads and headers
+- **Custom Parsers**: Add your own parsers for Stripe, GitLab, Slack, etc.

 ## 💡 Tips & Best Practices

- **Email Filtering**: Create an email filter for the subject line "‼️ Webhook Request Received" to organize incoming webhooks
+- **Use Parsers**: Use `/github`, `/grafana`, `/json`, or `/wxinteract` for prettier emails
+- **Email Filtering**: Create email filters based on subject patterns ("📤 GitHub", "🚨 Grafana") to organize webhooks
 - **Plus Addressing**: Use email plus addressing (e.g., `yourname+github%40gmail.com`) to track which services are sending webhooks
- **Timestamp in Emails**: Check the "Date Received" field to verify webhook timing and debug delivery delays
- **Parse the Body**: The raw body section contains the exact payload - perfect for copying into your code for testing
+- **Timestamp in Emails**: Check the timestamp in the header to verify webhook timing and debug delivery delays
+- **Standard Format**: Use the standard format (no parser) when you need complete raw data for debugging
+- **Create Parsers**: Build custom parsers for your favorite services - see [Parser Guide](PARSER_PROMPT.md)

 ## 📝 Error Handling

 ### Invalid Email Address
-If the email address in the URL is invalid or missing:
-```
-HTTP 400 Bad Request
-Invalid email address provided in URL path.
+If the email address in the URL is invalid or missing, you get a `400 Bad Request` with a JSON body:
+```json
+{
+    "ok": false,
+    "error": "invalid_email",
+    "message": "Invalid email address provided in URL path.",
+    "hint": "Encode @ as %40, e.g. /you%40example.com"
+}
 ```

+### Unknown Parser or Unparseable Payload
+The request still succeeds. The email uses the standard raw format and the response reports the parser name you asked for.
+
+### Mail Delivery Failure
+If the SMTP relay rejects the message you get a `502` with `"error": "mail_failed"`, so the sending service will retry rather than believe the webhook was delivered.
+
+### Body Too Large
+Bodies over 10 MB get a `413` with `"error": "body_too_large"`.

+
+## Testing
+
+### Using cURL
+
+Test individual event types using the sample payloads:
+
+```bash
+# Test Outbound SMS Submitted
+curl -X POST https://your-domain.com/test%40example.com/wxinteract \
+  -H "Content-Type: application/json" \
+  -d '{"data": {"status": "submitted", "message_id": "msg_123", "to": "+61412345678", "from": "+61387654321", "message": "Test message", "submitted_at": "2026-01-22T16:45:00Z", "campaign_id": "camp_001"}}'
+
+# Test SMS Opt Out
+curl -X POST https://your-domain.com/test%40example.com/wxinteract \
+  -H "Content-Type: application/json" \
+  -d '{"data": {"status": "opt_out", "phone_number": "+61412345678", "opt_out_at": "2026-01-22T18:15:00Z", "keyword": "STOP", "message_id": "msg_005", "from": "+61387654321"}}'
+```
+
+### Using Test Samples
+
+A complete set of test samples for all event types is available in `wxinteract_test_samples.json`.
+
+```bash
+# Test with submitted event
+cat wxinteract_test_samples.json | jq '.outbound_sms_submitted' | \
+  curl -X POST https://your-domain.com/test%40example.com/wxinteract \
+    -H "Content-Type: application/json" \
+    -d @-
+```
+
+---
+
+## Configuring in Webex Interact
+
+### Step 1: Log in to Webex Interact
+
+Go to your Webex Interact dashboard at https://interact.webex.com/
+
+### Step 2: Navigate to API Settings
+
+1. Click on **Settings** or **API** in the navigation menu
+2. Look for **Webhooks** or **API Callbacks** section
+
+### Step 3: Configure Callback URL
+
+1. Enter your webhook URL: `https://your-domain.com/{your-email}/wxinteract`
+2. Select the events you want to receive:
+   - ☑️ Outbound SMS - Submitted
+   - ☑️ Outbound SMS - Delivered
+   - ☑️ Outbound SMS - Failed
+   - ☑️ Shortlink Clicked
+   - ☑️ Inbound SMS Received
+   - ☑️ SMS Opt Out Received
+   - ☑️ Contacts Callback
+3. Save your configuration
+
+### Step 4: Test the Integration
+
+1. Send a test SMS from Webex Interact
+2. Check your email inbox for the formatted webhook notification
+3. Verify the email contains the correct information
+
+---
+
+## Email Organization Tips
+
+### Create Email Filters
+
+Set up filters based on the subject line patterns:
+
+- **All Webex Interact webhooks:** Subject contains "Webex Interact"
+- **Failed messages only:** Subject contains "❌ Webex Interact: Outbound SMS - Failed"
+- **Opt-outs only:** Subject contains "🚫 Webex Interact: SMS Opt Out"
+- **Click tracking:** Subject contains "🔗 Webex Interact: Shortlink Clicked"
+
+### Use Plus Addressing
+
+Track different campaigns or environments:
+
+- Production: `sms-prod%40mycompany.com`
+- Staging: `sms-staging%40mycompany.com`
+- Campaign A: `sms+campaignA%40mycompany.com`
+
+---
+
+## Troubleshooting
+
+### Parser Not Working
+
+If you're receiving raw webhook data instead of formatted emails:
+
+1. **Check URL:** Ensure `/wxinteract` is at the end of the URL
+2. **Check payload structure:** Parser expects `{"data": {"status": "...", ...}}`
+3. **Check the container logs:** `docker logs webhooks.dixon.cx` shows mail failures and parser errors
+
+### Missing Fields
+
+If some fields are showing as "N/A":
+
+- The webhook payload may not include those fields for that event type
+- Check the Webex Interact documentation for the specific event
+- Use the raw webhook format (without `/wxinteract`) to see the complete payload
+
+### Wrong Event Type
+
+If the event is being parsed as a generic event:
+
+- Check that `data.status` matches one of the supported values
+- Supported values: `submitted`, `delivered`, `failed`, `shortlink_clicked`, `received`, `opt_out`, `contact_created`, `contact_updated`

Author	SHA1	Message	Date
Andy Dixon	3145a40d7d	Codebase sync	2026-09-22 08:53:08 +01:00
Andy Dixon	680bfac014	Send as webhook.me.uk, add favicon, share image and SEO tags Mail now comes from no-reply@webhook.me.uk (DKIM, SPF and DMARC are set up for it) and the Message-ID uses that domain instead of the container hostname. The landing page gets a favicon, an Open Graph image, canonical/OG/Twitter/JSON-LD tags, robots.txt that keeps crawlers off email URLs, and a sitemap. Footer links to dixon.cx.	2026-09-22 08:50:20 +01:00
Andy Dixon	07701ba9cd	Clean white theme in black and Bristol blue, move to webhook.me.uk The landing page and the email shell drop the dark gradient look for a white background, black text and a single Bristol blue accent. Copy is unchanged. Email footers and docs now point at webhook.me.uk; the dixon.cx hostnames keep working.	2026-09-22 08:41:01 +01:00
Andy Dixon	2d0f98e041	Rewrite the service in Go and ship it as a static container The PHP app, Apache, and .htaccess are replaced by a single Go binary (standard library only). Routing, the JSON response, the landing page, the shared email design, and all four parsers are ported with the same output; JSON object keys are kept in sender order via an ordered decoder. - mail.go: SMTP delivery with quoted-printable body and RFC 2047 subject - main.go: routing, client IP from the proxy, /healthz, -check flag - render.go: email shell, escaping, table helpers, generic renderer - parser_*.go: github, grafana, json, wxinteract - main_test.go: handler, response shape, IP forwarding, every parser - Dockerfile: multi-stage build to distroless static, non-root, HEALTHCHECK - deploy/webhooks.dixon.cx.service: systemd unit for the container - README and PARSER_PROMPT updated for Go; IMPLEMENTATION_SUMMARY removed	2026-09-12 19:59:54 +01:00
Andy Dixon	a61da1f6e3	Move the parser guide into the repo and bring it up to date The guide lived one directory above the repo, so the README links were broken on GitHub. It also described the old layout: parsers inside index.php, a copied <style> block, and div-based tables. It now covers parsers/{name}.php, emailShell(), esc(), real table markup, case-insensitive headers, and local testing with a sendmail override.	2026-09-12 19:48:53 +01:00
Andy Dixon	5e731d5d11	Report the client IP nginx forwards, not the Docker bridge REMOTE_ADDR inside the container is 172.17.0.1. When the peer is a private or loopback address, use X-Real-IP (or the first hop of X-Forwarded-For) that nginx sets. Public peers cannot spoof it.	2026-09-12 19:21:13 +01:00
Andy Dixon	39ea06c3ee	Update README for JSON response, all four parsers, and email redesign	2026-09-12 19:20:14 +01:00
Andy Dixon	64c51d4f2b	Keep line breaks in values, handle scalar and string-array JSON - esc() helper escapes free-text values and converts newlines to <br>; used for commit messages, SMS text, annotations, and all JSON values - JSON parser accepts scalar bodies (string, number, bool, null) and renders them as a one-row table instead of falling back to the default template - Arrays of plain values render as one table under their path breadcrumb, so nested string lists are no longer anonymous - GitHub commits render as cards with a sha pill linked to the commit	2026-09-12 18:55:21 +01:00
Andy Dixon	b3da9fbb25	Render email metadata as real tables and redesign the shell Metadata blocks were divs styled with display:table. Nested blocks and orphan cells created phantom columns that squeezed the value column to a character or two. Every metadata block is now a real <table>/<tr>/<td>, which mail clients lay out reliably, and the value column always fills the remaining width. The shared shell gets a gradient hero header, timestamp pill, dark frame, and refreshed section, card, and code-block styling.	2026-09-12 18:47:20 +01:00
Andy Dixon	ae9348c0ad	Match GitHub event headers case-insensitively Header names arrive lowercase over HTTP/2 (the nginx front end enables it) and Apache preserves that case, so the X-GitHub-Event lookup missed and every email reported "Unknown". Normalise header keys once.	2026-09-12 18:41:32 +01:00
Andy Dixon	c1ec1adf85	Redesign landing page, JSON caller response, shared email shell - docs.htm: dark single-page redesign in plain CSS, live URL builder, all four parsers documented, Bootstrap CDN dependency dropped - index.php: respond with pretty-printed JSON (success and 400 error); email "Parsed Variables" block uses JSON instead of print_r - parsers/helpers.php: emailShell() provides one stylesheet, header and footer for every email template; five duplicated stylesheets removed	2026-09-11 18:23:25 +01:00
Andy Dixon	f3f58dbf95	Set webhook email sender identity	2026-09-11 18:10:16 +01:00
Andy Dixon	3d88ae2132	Added JSON parsing	2026-01-26 13:12:15 +00:00
Andy Dixon	ae3e3f8488	Break parsers into subfolder	2026-01-22 17:18:35 +00:00
Andy Dixon	ee65789675	Add implementation summary documentation	2026-01-22 16:59:30 +00:00
Andy Dixon	2a45e6430c	Add comprehensive Webex Interact parser guide - Detailed documentation for all 7 event types - Configuration instructions - Testing examples with cURL - Email organization tips - Troubleshooting section - Links to official API documentation	2026-01-22 16:58:40 +00:00
Andy Dixon	1d336e4cac	Add Webex Interact webhook parser - Added wxinteractParse() function supporting all SMS API events: * Outbound SMS (submitted, delivered, failed) * Shortlink clicked * Inbound SMS received * SMS opt out * Contacts callback - Helper functions for each event type with formatted HTML - Test samples file for all event types - Updated README with Webex Interact documentation - Follows existing parser style and security guidelines	2026-01-22 16:57:55 +00:00
