## Other responses

- `400`: The request did not match the schema
- `401`: No valid credentials. WWW-Authenticate names the protected resource metadata to start from
- `403`: The credentials are valid but not enough: the token lacks the scope, or the action needs a browser session rather than an app token

- `500`: Internal server error
