Hi Eric, Thanks for the reply. I'm still unbale to get this working correctly by changing the RequestHeader namespace.
My updated is: <?xml version='1.0' encoding='utf-8'?> <soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'> <soap:Header> <RequestHeader xmlns='https://adwords.google.com/api/adwords/cm/ v201109'> <authToken>xxxx</authToken> <applicationToken>yyyy</applicationToken> <developerToken>zzzz</developerToken> </RequestHeader> </soap:Header> <soap:Body> <get xmlns='https://adwords.google.com/api/adwords/mcm/v201109'> <selector /> </get> </soap:Body> </soap:Envelope> (Most of this is taken from the Make a raw API call NoClientLibrary guide for .net (http://code.google.com/p/google-api-adwords-dotnet/ wiki/NoClientLibrary#Option_1:_Make_a_raw_API_call) so should be correct? The response is now: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <soap:Fault> <faultcode>soap:Server</faultcode> <faultstring>Unmarshalling Error: unexpected element (uri:"https:// adwords.google.com/api/adwords/cm/v201109", local:"RequestHeader"). Expected elements are <{https://adwords.google.com/api/adwords/mcm/ v201109}ApiExceptionFault>,<{https://adwords.google.com/api/adwords/ mcm/v201109}RequestHeader>,<{https://adwords.google.com/api/adwords/ mcm/v201109}ResponseHeader>,<{https://adwords.google.com/api/adwords/ mcm/v201109}get>,<{https://adwords.google.com/api/adwords/mcm/v201109} getResponse> </faultstring> </soap:Fault> </soap:Body> </soap:Envelope> I'm sure there is something stupid I've missed here, but I'm not sure what that is! Thanks again.
