Upgrading your client library to v22.0.0,.AdSoap Client Error.

[Saritha Gangareddy]

When I upgraded from Google Adwords V201705 to V201708 & V201710 I am getting error like 

"Could not find default endpoint element that references contract 'Google.Api.Ads.AdWords.v201710.AccountLabelServiceInterface' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."

Please can any one help me out of this issue.

Hi Saritha, 

Could you confirm if you are trying to upgrade to V201710 version of the API and using the Ads API .NET Client Library - v22.0.0? If so, this .NET library version only supports until V201708. Please check the library link for more details. My suggestion is to upgrade the .NET library to the latest available version, which is Ads API .NET Client Library - v23.1.0. It is also recommended to skip v201710 and migrate directly to v201802. Please check this blog post for more resources that will help you with the migration.

Please let me know if you have any additional questions.

Thanks,

Thank You Sreelakshmi,

First I tried to upgrade the V201802 only then I got the same exception. Then I tried with V201710 even though I am getting same exception.

For both versions I am getting the above error.

Hi Saritha, 

A given library version might not support all versions of the API. If you are using the latest version of the .NET client library, which is Ads API .NET Client Library - v23.1.0, you should be able to make API calls against the V201710 and V201802 version of the AdWords API. If you are using the correct version of the client library, could you please share the complete error logs so that we can troubleshoot the issue? You could share the logs using reply privately to author option.
