Remove LiveKit participant

Removes a participant from a LiveKit room, forcibly disconnecting them. Access is authorized via metadata.auth_id check.

Note: This does not invalidate the participant’s token. To prevent rejoining, use short-lived tokens and avoid issuing new tokens to removed participants.

Arguments

state - Shared application state containing LiveKit configuration
auth - Authentication context from middleware
request - Request with room name and participant identity

Returns

Response - JSON response with removal status or error

Authorization

When auth.id is present: Requires room.metadata.auth_id == auth.id
When auth.id is absent: Access is allowed (backward-compatible mode)

Errors

400 Bad Request - Empty room name or participant identity
404 Not Found - Room/participant not found or access denied (masked)
500 Internal Server Error - LiveKit not configured or removal failed

Flow

Validate request fields are not empty
Check room access via metadata.auth_id
Verify participant exists in the room
Remove the participant
Return success or appropriate error

Authenticated (`auth.id` present)	Requires `room.metadata.auth_id == auth.id`.
Unauthenticated (`auth.id` absent)	Access is allowed (backward-compatible mode).

Room names are used exactly as provided. No prefixing or modification is applied.

Request

Requires room_name and participant_identity in the request body.

Error responses

Status	Condition
`400 Bad Request`	Empty room name or participant identity.
`404 Not Found`	Room/participant not found or access denied (masked for security).
`500 Internal Server Error`	LiveKit not configured or removal failed.

This endpoint does not revoke the participant’s token. To prevent rejoining, use short-lived tokens and avoid issuing new tokens to removed participants.
