Coffee Room with Push to Slack

Hi

Thought it would be cool to have a jitsi room that could be used as a coffee/hangout/break room. But to make people aware as soon as someone enters the room, i would like to push a message into a slack channel every time a member enters the room.

That brings me to the question: What is the easiest way to query via HTTP request (or locally on the jitsi machine) how many users are in a channel?

Thanks,
Markus

This can be done with a custom prosody module. There is already in the utils a function doing http query.
