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 Hook Bell.

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. Hook Bell 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"
