Hi #MastoAdmin and ActivityPub developers
I’m currently testing an OSSN-based social platform that federates via ActivityPub. Hashtags and Likes are received properly (via signed Create
and Like
activities), but replies to our posts aren’t being received.
Here’s what I need help with:
Our posts include a valid
Note
with:
to
:https://www.w3.org/ns/activitystreams#Public
url
: pointing to our canonical post URLid
: full post URL (same asurl
)published
,attributedTo
, etc.
When replying from Mastodon to one of our posts, the ActivityPub message does contain an
inReplyTo
with the full URL of the original post.
However:
No
Create
activity with Note
and inReplyTo
is received on our inbox endpoint.
We do receive
Like
, Undo
, and Delete
activities without problems.
Question:
Under what exact conditions does Mastodon send a federated reply (as a
Create
with Note
and inReplyTo
) to the original post’s inbox?
Do we need to:
- support
Accept
for incomingFollow
? - add a
cc
field with the replier’s inbox? - expose a
replies
collection? - be whitelisted somehow?
Thanks for any pointers!
