Calendar Event Sync

Generates and returns a persistent sync identifier for the authenticated user's calendar.

The sync identifier can be used to construct a public iCal feed URL that external calendar applications (e.g. Apple Calendar, Google Calendar) can subscribe to. The identifier is stable across calls — repeated requests return the same identifier unless it has been regenerated.

Use the returned sync_id with GET /api/calendar/v4/calendar/sync/{sync_id} to retrieve the iCal feed. The ical_export setting must be enabled for the organization for iCal export to be available to users.
