Errors

The API uses standard HTTP response codes and all the successful requests will return the status code 200. Because the API works like a proxy for the internal GraphQL API the error of an unsuccessful request can be produced either by the proxy or by the GQL API itself.

Error responses will usually have a status code that's not 200 and the response body will represent an array of errors where each error has a "message" field.
