Response Codes

Content API uses standard HTTP response codes to indicate the success or failure of a request. In general, codes in the 2xx range indicate success, codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a search request was malformed, etc.), and codes in the 5xx range indicate an error with the Content API servers.

A complete list of possible response codes is as follows:

200	Success	The request completed successfully and content was returned. Nothing to see here, please move along.
204	Success	The request completed successfully against a valid resource but no content was required to be returned.
