For people interested in #ActivityPub #C2S (client to server), the #GoActivityPub services have gained the ability to dynamically register OAuth2 clients based on RFC7591.

The easiest to test is the ONI project that can be directly run without much setup: https://git.sr.ht/~mariusor/oni

@mariusor woot! 🥳

Which ActivityPub applications support Client-to-Server (C2S)?

@smallcircles thank you Arnold.

@mariusor

The codeberg issue is kind of still an ugly scratch pad rn. The thing awaits a follow-up where stuff is more organized and easier to drill down into. Proper docs eventually.

A first step may be to name the discrete and granular building blocks that one should focus on when starting out on an #ActivityPub client-to-server adventure quest. Give them consistent names. And then to map all the various projects to that as a MDN-like who-supports-what table.

@smallcircles GoActivityPub servers support following things for Client to Server:

* Accessing objects and collections
* Filtering the collections through query parameters (eg. ?type=Create)

* Support for OAuth2 actor endpoints information and authorization
* Support for .well-known information (webfinger and now, OAuth2 client registration)

* ACLs for accessing them based on recipients list - this includes collection filtering of individual items
* ACL principal extraction from OAuth2 Bearer token (or from HTTP-Signature)

* Outbox Activity validation & processing (which I think is the main one :D)

( @smallcircles in case you wanted a starting point )

@mariusor wonderful, thank you. It is updated on codeberg now

@smallcircles sometime in the future I'll have a bit more explanations about the different things to incorporate in the #GoActivityPub documentation.

I'll try to remember to ping you.

@mariusor this is great, I'm looking forward to testing this

When you do, feel free to ping me with questions (here or on the mailing list).
