Reading HTTP response status and error messages

With every HTTP request, the Incremental Feed API returns a response status. This topic lists and describes some status codes and error messages that Sitecore Discover returns in response to POST requests you send to the Incremental Feed API. You can also refer to the complete list of HTTP response codes that Discover can return.

This topic also provides a detailed description of the error object.
