Error: Code 879: Your HTTP header is invalid or inconsistent with your XML input or old format HTTP header input.

This error is returned if a mismatch is detected between the values in the HTTP headers and the body of the XML request. For example, if this HTTP header is passed in:
X-EBAY-API-DETAIL-LEVEL: 16 but the XML contains:
0, then this error will occur.
