I'm trying to integrate with Google Oauth 2.0 and have got as far as getting the authorization token. When trying to fetch for the access and refresh tokens I keep getting an error about my app not complying with validation rules. My app is still in testing mode, and I have valid redirect urls configured. Any one know what I might have misconfigured?
{ "error": "invalid_request", "error_description": "You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure. You can let the app developer know that this app doesn't comply with one or more Google validation rules." }
Appreciate any help! Thanks!
