Cal.com Booking Notifications for Busy Founders

You're in the middle of deep work when someone books a meeting on your Cal.com calendar. You won't know until you check your email — unless you have HookBell.

Why monitor Cal.com bookings?

If you're a founder, freelancer, or anyone who takes meetings through Cal.com, instant booking awareness is a game-changer. Knowing the moment someone books, cancels, or reschedules lets you prepare faster and avoid no-shows. HookBell sends a push notification to your phone for every Cal.com booking event.

Supported events

  • BOOKING_CREATED — "New booking: John Doe — Jan 15 at 2:00 PM"
  • BOOKING_CANCELLED — "Booking cancelled: Jane Smith — Jan 16"
  • BOOKING_RESCHEDULED — "Rescheduled: John Doe → Jan 17 at 3:00 PM"

Setup walkthrough

  1. 1. Create a connection — In HookBell, create a new connection for Cal.com and copy the webhook URL.
  2. 2. Add the webhook in Cal.com — Go to Settings → Developer → Webhooks in Cal.com. Add a new webhook subscriber and paste the HookBell URL. Select the booking events you want to track.
  3. 3. Stay in the loop — Every booking event triggers a push notification with the attendee name, date, and time.
