## Other responses

- `400`: Bad Request
- `401`: Unauthorized. On api.telnyx.com, authentication is enforced by the API gateway before the request reaches the Meeting service, so a missing or invalid API key returns the standard Telnyx error envelope (`{"errors": [{"code": "10009", ...}]}`) rather than the single-`error` shape below.
- `403`: The authenticated credential is not permitted to perform this operation.
- `404`: Not Found
- `409`: Conflict
- `413`: Payload Too Large
- `422`: Unprocessable Entity, including an unsupported capability
- `429`: Authentication is temporarily overloaded. Retry after the number of seconds in `Retry-After`.
- `500`: Internal Server Error
- `502`: The meeting provider rejected native chat delivery.
- `503`: A required feature or dependency is not configured, authentication is unavailable, or (`assistant_lookup_unavailable`) the assistant could not be read to check its avatar.
