Hello, About 3 weeks ago we started seeing this error when we refresh the access token for many random accounts, { "error" : "invalid_grant" }. We never had any problems refreshing access tokens up until now. Also, not all accounts are having problems refreshing their tokens; many refresh just fine. To temporarily fix the issue we have been reauthorizing each account, but other accounts start to have the same problem. The only information I could find on the forum is that the refresh token has manually been revoked, which doesn't make sense to me. I've read through the documentation at "https://developers.google.com/adwords/api/docs/guides/authentication"; and it looks like our TokenUrl, AuthUrl and Scope are up to date. Any help is greatly appreciated, thanks.
Get Authorization Code: https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=XXXXXX&scope= https://www.googleapis.com/auth/adwords &response_type=code&access_type=offline&approval_prompt=force"; Below is an example of the url and parameters we are using to retrieve initial access and refresh token: https://www.googleapis.com/oauth2/v3/token?code=XXXXXXXXXXXXX&client_id=XXXXXXXXX&client_secret=XXXXXXXXX&grant_type=authorization_code&redirect_uri=XXXXXXXX Below is an example of the url and parameters we are using to refresh access tokens: https://www.googleapis.com/oauth2/v3/token?refresh_token=XXXXX&client_id=XXXXX&client_secret=XXXXX&grant_type=refresh_token -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ 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.
