I’m not sure if this is related or not, but we also are seeing issues with participant_* webhooks. It’s a JWT app, and we have a “master account” setup with subaccounts. The webhook config screen shows “Event notifications can be subscribed for all users in the master account or in both master account and all subaccounts.”, and I have selected “All users in the account and subaccounts”.
I have just a few hooks selected: create/start/end and participant joined for both meetings and webinars. We are getting all events for users in the master account (including participant joined), and we are getting create/start/end events for meetings hosted by users in the sub account(s), but we are not getting participant joined events for any meetings in the sub account(s).
Not sure if it’s possibly related to webhook performance or a bug, as the behavior (master account vs. subaccount only affected one of several different event types) seems consistent.
