Every endpoint on this page requires either a Clerk-issued JWT (Authorization: Bearer <token>) or an organization API key (x-api-key: pk_…). Anonymous calls return 401 Unauthorized. See Authentication for the full setup.
Use this endpoint to discover the phone_number_id you need when triggering an outbound call. The returned id values are stable — cache them on your side.
