   @activitypub
   Is this group the right place to ask about details regarding implementation of #ActivityPub?

   I'm right now at a very basic first step: #Webfinger and users/actors lookup, so that the search from within a #Mastodon instance should find a remote user (e.g. using #Tusky).

   Unfortunately it looks like my implementation is missing something... ;-)

   Btw.: Using plain #PHP.

     With both the #ActivityPub hashtag and the #Guppe group you'll get best reach on the fedi.

     Other than that there's the #SocialHub community to ask, but it also has a great archive of past discussion to search in.

     Good starter topic: https://socialhub.activitypub.rocks/t/guide-for-new-activitypub-implementers/479

     Other than that I co-maintain 3 fedi-related lists on https://delightful.club with many projects codebases to check out.

     Thanks for your answer.

     Yes, the response from my server.

     I currently try to get the first part of this to work:
     https://blog.joinmastodon.org/2018/06/how-to-implement-a-basic-activitypub-server/

     So my server should respond in the right way to a webfinger request and a user lookup. And i test this directly from within #Mastodon using this account to do a search (usually just let #Tusky do a search).

     The response form your server? No that doesn't need a signature. We use http signature to verify the identity of the *requestor*

     Thanks for your reply.

     Discovered the first mentioned URL right before my toot. It also links to "How to implement a basic ActivityPub server" (Mastodon)... that i've read multiple times... unfortunately it is good to explain the concept, but missing details for implementation.

     E.g. does the reply to a request for a specific user require a HTTP signature?

     @nick @datatitian @humanetech @activitypub have you tried using https://webfinger.net/ it can help to see if everything is well formed

     also feel free to look at how wordpress is doing it https://github.com/pfefferle/wordpress-activitypub/blob/master/includes/rest/class-webfinger.php#L68

     @datatitian @humanetech @activitypub

     And now i'm trying to figure out, what my implementation is missing at this point.

     Unfortunately i can't see any message from the #Mastodon server... in this case norden.social, where my account here is located.

     Good to know, that there is no HTTP signature required at this stage.

     What about the public key? Any restrictions or limitations?

     Any ideas to track that down?

     @datatitian @humanetech @activitypub

     So i type in a search (using #Tusky to have a real request, that should be proven) for an existing user account on my (test) server. Response: Nothing...

     I can see one incoming webfinger request on my server and two requests for the users. So i assume, it will be satisfied with the webfinger result, but not with the user lookup, so it tries again. At least this is my current theory...
