The API uses HTTP status codes to indicate an error has occurred while processing a request.

401	The request could not be authenticated
403	The user is not authorized to access the requested resource
404	Either the request was made to an incorrect endpoint, or the requested resource doesn't exist
415	API Request Error is displayed because you need to transcode the media you are trying to upload.
429	We've received too many API requests from this account over the last hour
