Run the Google > OAuth > InitializeOAuth Choreo, specifying the Client ID from the app you registered at Google and at least one of the following Scopes:
Open a new web browser, navigate to the authorization URL returned by the InitializeOAuth Choreo, and click "Accept" to grant the app access to your Google account.
Run the Google > OAuth > FinalizeOAuth Choreo, specifying the callback ID returned earlier by the InitializeOAuth Choreo. This process will return a Refresh Token which can be used along with the Client ID and Client Secret to authenticate with Google.
This short video demonstrates how to use our OAuth Choreos, and it's a good idea to take a break and watch it now before you dive into this step.
