We've been downloading AdWords reports using a server app over OAuth2 for a while, now. We're using the Google AdWords NuGet library (
https://github.com/googleads/googleads-dotnet-lib/) to handle the raw interface, and it works fine, though updating API versions are very painful. We started getting the dreaded error again:
You are accessing an AdWords API version v201609
that has been discontinued.
I installed the latest version of the NuGet library and updated our refresh token using adwords_dotnet_lib_v22.2.0 version of OAuthTokenGenerator. This is using the same client ID and secret that's been working for a year, but suddenly I'm getting permission denied errors with the new library.
How do I get reports to download again? Our marketing department relies on this data to do their jobs.
