Does anyone know why I’m getting the above error when trying to Upload Clicks to google ads? got this in the logs:

Request made: ClientCustomerId: xxxxxx-xxxxx.apps.googleusercontent.com, Host: googleads.googleapis.com, Method: /google.ads.googleads.v11.services.ConversionUploadService/UploadClickConversions, RequestId: None, IsFault: True, FaultMessage: Getting metadata from plugin failed with error: ‘GoogleRefreshTokenClient’ object has no attribute ‘before_request’

Answer

It looks as if you’re using the googleads.oauth2.GoogleRefreshTokenClient class, which was the way to create credentials in the googleads package for the Adwords API.

This class is no longer in used for the google-ads (Ads API) package, use google.oauth2.credentials.Credentials instead.

The easiest way is to use the utility function google.ads.googleads.oauth2.get_installed_app_credentials():

credentials = google.ads.googleads.oauth2.get_installed_app_credentials(
    client_id=client_id, 
    client_secret=client_secret,
    refresh_token=login_user.refresh_token
)
