API OverviewRoom Participants

Get a single room participant

View as Markdown
Get one [room participant](/api/room-participants). `{uuid}` is the participant's session UUID. It is the same identifier returned by `GET /api/v1/rooms/{room_id}/participants`. The response uses the same `{uuid, muted}` participant object as the list endpoint. Voice activity is not included in this object. Receive voice activity changes through the `room.participant.voice_activity_changed` webhook when the room was created with `voice_activity_events: true`.
