Content-Type	header/body	String	If the operation fails, this value is the MIME type of the error text in the response body.
X-Trans-Id	header/body	String	A unique transaction ID for this request. Your service provider might need this value if you report a problem.
Date	header/body	DateTime	The transaction date and time. The date and time stamp format is ISO 8601: `CCYY-MM-DDThh:mm:ss-hh:mm`. For example, `2015-08-27T09:49:58-05:00`.
