This article explains the various status codes and error messages you might receive when using the Paazl REST API. The information is grouped by endpoint.

Status codes are returned in the the API call's response header, and, where relevant, error messages are returned in the the API call's response body.

Note

The REST error codes you might receive could be a standard HTTP error code or one we have customized for the Paazl REST API. This article only explains those error codes and messages that we have modified specially for the Paazl REST API.
