So there seem to be three possible endpoints to post a chat message to… somewhere:
This endpoint requires a userId, but I’m looking to do this with a service app (no user).
This endpoint is meant to be used by chatbots, so (maybe?) would require an OAuth request to convert the JWT into an access token. So how would I do this?
This is marked as deprecated, and the details are insufficient to know if it would work anyway.
So, any pointers?
