Hi, Do you get this error when you run the curl command that was shared or when you run the client library examples <https://github.com/googleads/googleads-dotnet-lib>? Could you try opening a new incognito window, then generate the client id and secret using a valid AdWords user login. Also, please make sure you are using the correct scope which is: "https://www.googleapis.com/auth/adwords". After that, please generate the refresh token using the OAuthTokenGenerator.exe <https://github.com/googleads/googleads-dotnet-lib/wiki/API-access-on-behalf-of-your-clients-(web-flow)#step-2---setting-up-the-client-library>. Then, please use those credentials to run GetCampaigns.cs <https://github.com/googleads/googleads-dotnet-lib/blob/master/examples/AdWords/CSharp/v201802/BasicOperations/GetCampaigns.cs> or GetCampaigns.vb <https://github.com/googleads/googleads-dotnet-lib/blob/master/examples/AdWords/Vb/v201802/BasicOperations/GetCampaigns.vb> and let me know if you still get errors.
