Versions
See the documentation for product versioning. We also recommend reading the section about error handling.
Errors and return values
Sometimes things don't go as planned. The API will return a (hopefully)
explanatory message, formatted as HTML (if using a browser or sending an
Accept: text/html request header), otherwise as plain text.
For more information, see the HTTP status codes documentation. In addition you can also check the HTTP status code and the X-ErrorClass response header when using an automated client.
ErrorClass header
In addition to the HTTP Status Code the API also returns an X-ErrorClass response header which might explain further the cause of the error. The following codes are currently used:
