Notify Slack about new Cal.com bookings

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 Slack channel before activation. Messages contain the title, booking UID, start time and event time; no email addresses are copied.

Questions

Template FAQ

Does the template copy someone else's credentials?

No. FastHook creates a disconnected Draft. Connect your own Calcom, Slack accounts before activation.

Can I change the Steps and mappings?

Yes. The copied Workflow is an editable Draft. Review every Step, input, mapping, and route before you activate it.

What is copied into my workspace?

FastHook recreates the Trigger configuration, Action Steps, routes, and mappings with new IDs. Provider accounts, credentials, and secrets are never copied.

When does the Workflow start running?

Only after you connect the required accounts, finish the configuration, and explicitly activate the Draft.
