The service uses standard HTTP return codes - as follows:
- 200 OK - the request has succeeded.
- 400 Bad Request - The server will not process the request due to XML-schema validation error.
- 401 Unauthorized - The request has not been applied because it lacks valid authentication credentials.
- 403 Forbidden - The access is permanently forbidden and tied to the application logic, such as insufficient rights to a resource.
- 405 Method Not Allowed - The request method is known by the server but is not supported by the target resource (we only support HTTP POST).
- 500 Internal Server Error - The server encountered an unexpected condition that prevented it from fulfilling the request.
- 503 Service Unavailable - The server is not ready to handle the request. Common causes are a server that is down for maintenance or that is overloaded.
