HTTP response codes

The HTTP response code tells your application whether the API could process your request.

The codes are grouped into ranges. For a simple error handling strategy it's often sufficient to only test the first character.

  • 200-299: Success. The server has done what the client requested.
  • 400-499: Client Errors. Generally the client must ammend the request.
  • 500-599: Server Errors. The server has a problem that is not related to the request.
