ICS Calendar Subscription

Certain calendar services cannot be connected via two-way APIs, but publish subscription feeds in iCalendar (.ics) format. LockMyCal can subscribe to these feeds and incorporate their events into your availability calculations.

Common Sources:

  • Private secret Google Calendar iCal URLs,
  • Published Outlook web calendars,
  • Apple shared calendars,
  • Room reservation exports and third-party booking systems.

How Subscriptions Work

  • Read-Only: Events from subscribed feeds block busy slots and display in your dashboard calendar. LockMyCal never writes to subscription feeds, so they cannot be selected as destination calendars for new bookings.
  • Automatic Refresh: The feed file is refreshed in the background at regular intervals.
  • Calendar Limits: In the LockMyCal cloud, subscriptions count toward your connected calendar quota (Free: 2, Pro: 6).

Connection Steps

  1. In your dashboard, open Integrations → Calendars → Connect a calendar and select Calendar Subscription.
  2. In Feed URL, paste the direct .ics link.
  3. Name the integration and save.

Tip

If a feed URL changes or is revoked, LockMyCal will notify you to update the subscription address.
