Get Google API key
Follow the instructions from step 1 in the Browser Quickstart tutorial.
Restrict the API key
Set application and API restrictions.
Make your calendar public
Refer to the following help topic: Create & manage a public Google calendar.
Get the calendar ID
Open Google Calendar settings, choose the calendar to be integrated, and copy its ID from the Integrate calendar section.
