Hi,
I'm trying to access Google AdWords Application, but I can't get the Refresh Token. I'm trying with an official MCC account (Token it's pending approval) and a Testing MCC Account. Using .Net Library I get the error "invalid_client" (see attachment). Based on other posts, I tried to create an app in Google Developers Console following this guide:
https://code.google.com/p/google-api-adwords-php/wiki/OAuth2
But, I don't have the "My Registeres Applications" option. You can see in attachment the error that I get trying to access OAuth and where I'm taking the data from (testing account)
Thank you,
