Disconnecting participant in conference via API

Trying to kick a user out of a conference call using the Conversations API. I’m hitting PATCH /api/v2/conversations/conferences/{id}/participants/{participantId} with the body { "status": "disconnected" } but I keep getting a 400 Bad Request. The documentation is sparse on the exact JSON structure needed. What am I missing?

The body needs the status field inside a conference object, not at the root level. Try this payload instead.

{
 "conference": {
 "status": "disconnected"
 }
}
