I've just downloaded the REST API Modular Input, and I have some doubts about its configurations using OAUTH2.
Here are two fields I'm in doubt in:
OAUTH 2 Token Refresh URL -> what URL should I put here? Assuming that I'll work with Google APIs;
OAUTH 2 Token Refresh Properties -> what properties should I put here?
I believe that with these fields correctly configured, I can achieve my goal.
Your token refresh URL should be : https://www.googleapis.com/oauth2/v3/token
Your token refresh properties should be : grant_type=refresh_token
