  1. Get Google API key
    Follow the instructions from step 1 in the Browser Quickstart tutorial.

  2. Restrict the API key
    Set application and API restrictions.

  3. Make your calendar public
    Refer to the following help topic: Create & manage a public Google calendar.

  4. Get the calendar ID
    Open Google Calendar settings, choose the calendar to be integrated, and copy its ID from the Integrate calendar section.

  5. Set up the JavaScript Scheduler
    Configure the CustomStore to load data from Google Calendar as shown in this demo. If a timeZone is specified in the JavaScript Scheduler, ensure it is the same as in Google Calendar.
