Status Codes and Error Responses

Each request returns a status code or error response to indicate whether the request was successful.

When an error occurs or when a response is successful, the response header contains an HTTP code, and the response body usually contains:

HTTP response code	Description
2xx	Query successfully executed and response data returned.
400	(BAD_REQUEST) The argument or parameter you supplied in the request isn’t valid.
403	The request was refused because the data source isn’t connected to Customer 360 Data Manager or doesn’t allow data to be queried.
404	The job, file, or data source included in your query can’t be found.
429	Too many requests being processed at the same time. Try again.
500	An error has occurred, so the request couldn’t be completed. Try again or contact Salesforce Customer Support.
503	Either your data source is unavailable or the connection to it timed out.
