I'll see if I can get enough detail in here. Please hit me with questions if I leave something out. I'm trying to move an application from using the ClientLogin to OAuth.
No matter what I do, I always get this error back from the service. <soap:Fault> <faultcode>soap:Server</faultcode> <faultstring>[AuthenticationError.OAUTH_TOKEN_INVALID @ ; trigger:'<null>']</faultstring> <detail> <ns2:ApiExceptionFault xmlns="https://adwords.google.com/api/adwords/cm/v201502" xmlns:ns2="https://adwords.google.com/api/adwords/mcm/v201502"> <message>[AuthenticationError.OAUTH_TOKEN_INVALID @ ; trigger:'<null>']</message> <ApplicationException.Type>ApiException</ApplicationException.Type> <errors xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AuthenticationError"> <fieldPath/> <trigger><null></trigger> <errorString>AuthenticationError.OAUTH_TOKEN_INVALID</errorString> <ApiError.Type>AuthenticationError</ApiError.Type> <reason>OAUTH_TOKEN_INVALID</reason> </errors> </ns2:ApiExceptionFault> </detail> </soap:Fault> Code wise, all I'm doing is this. Even this I snagged from the example code, just because I wanted to see if something in my existing app was messing with things. var user = new AdWordsUser(); AdsOAuthProviderForApplications oAuth2Provider = (user.OAuthProvider as AdsOAuthProviderForApplications); oAuth2Provider.RefreshAccessToken(); ManagedCustomerService managedCustomerService = (ManagedCustomerService)user.GetService(AdWordsService.v201502.ManagedCustomerService); Selector selector = new Selector(); selector.fields = new String[] { "CustomerId", "Name" }; ManagedCustomerPage page = managedCustomerService.get(selector); Configuration wise, I'm set like this. I know it doesn't make much sense, given that I had to blank out so much: <add key="DeveloperToken" value="xxxxxxxxxxxxxxxxxxxxxx" /> <add key="ClientCustomerId" value="111-111-1111" /> <add key="OAuth2Scope" value="https://www.googleapis.com/auth/adwords" /> <add key='AuthorizationMethod' value='OAuth2' /> <add key='OAuth2ClientId' value='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com' /> <add key='OAuth2ClientSecret' value='xxxxxxxxxxxxxxxxxxxxxxxx' /> <add key='OAuth2RefreshToken' value='1/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' /> <add key="OAuth2Mode" value="APPLICATION" /> I used the OAuthTokenGenerator to generate the info using the email address for the MCC. -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
