Google Calendar - where does the private key come from?

[Richard238]

Where, within Google, do I create a PRIVATE_KEY for Google calendar basic.ics?
I’ve searched Google, can find mapping APIs and umpteen other tools, but nowhere to create calendar private keys.

Thank you.

Found it:

In Google Calendar, hover over the required calendar, drop-down arrow, calendar settings.

Click the green ICAL button next to ‘Private addresses’

Pop-up gives required URL.
