Hello Jeff
I think I have the same problem as adchased, I've -
- downloaded and built the google-api-adwords-dotnet project & added a
reference to the dll
- added AdWordsUser.cs to my ASP.NET web project
- amended the web.config so it includes the custom configuration
'adwordsHeaders' section
- added login details that have worked in other test scripts
but when I try and make a call to CampaignService I get the following
null
System.ArgumentNullException: Value cannot be null. Parameter name:
type at System.Activator.CreateInstance(Type type, Boolean nonPublic)
at com.google.api.adwords.lib.AdWordsUser.getService(String name) at
CampaignServiceFuncs.AddCampaign()
How can I switch to WSDL?
Thanks
JN
