Question
People commonly ask on the Zoom Developer Forum:
How can I reliably get the current participants in an active Zoom meeting (including when people move between breakout rooms)?
Answer
For real-time, reliable participant presence (including breakout rooms), use participant webhook events rather than polling the Metrics participants endpoint. Then maintain your own in-memory/database state as events arrive.
- Subscribe to participant webhooks:
- meeting.participant_joined
- meeting.participant_joined_breakout_room
- and the corresponding participant leave events
-
On each “joined” event, add/update the participant in your store with their current context (e.g., meeting vs. which breakout room).
-
On each “left” event, update/remove the participant accordingly. This event-driven list will stay accurate as users join/leave and move between breakout rooms.
