Get the Google Calendar Pro add-on here. Setting up an Google OAuth client is almost as easy as obtaining a Google API key as used by the default settings in the core Simple Calendar plugin. Here are step-by-step instructions to configure a Google OAuth client for Google Calendar Pro: 1. Navigate to the Google Developers Console. 2.
1 Open your Google Calendar app page using your Google account. 2 Navigate to your subscribed/available Google calendars list (usually bottom left side). 3 To get to your calendar settings, hover over the calendar you wish to work on and click the three vertical dots that appear to the right – this will bring up a dropdown menu, click Settings and sharing.
You can use CalendarList() with a GET request as shown in the Google Calendar API here. I tested this by retrieving my own calendar id by passing in the "primary" keyword as described in the documentation linked above.
