# Update conference participant

`POST /conferences/{id}/actions/update`

Update conference participant supervisor_role

## Path parameters

- `id` string, required

## Request body

- UpdateConferenceRequest
  - `call_control_id` string, required — Unique identifier and token for controlling the call
  - `command_id` string — Use this field to avoid execution of duplicate commands. Telnyx will ignore subsequent commands with the same `command_id` as one that has already been executed.
  - `supervisor_role` 'barge' | 'monitor' | 'none' | 'whisper', required — Sets the participant as a supervisor for the conference. A conference can have multiple supervisors. "barge" means the supervisor enters the conference as a normal participant. This is the same as "none". "monitor" means the supervisor is muted but can hear all participants. "whisper" means that only the specified "whisper_call_control_ids" can hear the supervisor. Defaults to "none".
  - `whisper_call_control_ids` string[] — Array of unique call_control_ids the supervisor can whisper to. If none provided, the supervisor will join the conference as a monitoring participant only.
  - `region` 'Australia' | 'Europe' | 'Middle East' | 'US' — Region where the conference data is located. Defaults to the region defined in user's data locality settings (Europe or US).
