• delete_ical_subscription Delete an external iCal feed subscription. Events previously synced from the feed are no longer refreshed.
• sync_ical_subscription Start an immediate fetch of an external iCal feed instead of waiting for the next scheduled poll. Returns {"status":"syncing"} as soon as the fetch has started;
