Ready-made Workflow
Notify Telegram when a Cal.com booking is cancelled
Connect Cal.com using a dedicated API key. FastHook creates a signed account-level webhook when activated and removes owned subscriptions after the last consumer is paused. Team-owned booking links may need their own team/event-type hook. Cal.com sends booking data to the selected destination. No account IDs, resource IDs or secrets are included. Manual reruns can duplicate destination effects. Test with fictional bookings before activation. Choose your Telegram bot and chat before activation. Messages contain the title, booking UID, start time and event time; no email addresses are copied.
