Cal.com events, straight into Airtable
Every new booking, cancellation, or reschedule — posted to Airtable the moment it happens. No Airtable app to install, no monthly automation subscription.
The gap this fills: Cal.com doesn't ship an official Airtable app. If you want new booking, cancellation, or reschedule to show up in Airtable the moment it happens, the usual options are a paid third-party bot, custom code, or routing everything through a $20–50/month automation platform just to move one webhook from one URL to another. ZestyGlue does exactly that one thing for $9/month.
What it looks like
ZestyGlue
Cal.com — Booking Created
A real Cal.com event, shown as ZestyGlue formats it for Airtable.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new Cal.com → Airtable connector. You'll get a unique webhook URL right away.
- Point Cal.com at it. Go to Settings → Developer → Webhooks → add a webhook, paste in your ZestyGlue webhook URL, and select the trigger events you want.
- (Optional) set a secret. Cal.com can sign its payloads if you set a secret on the webhook — enter the same value into ZestyGlue for extra verification, though it isn't required to get started.
- Point Airtable at ZestyGlue. Create a token at airtable.com/create/tokens scoped to your base, copy the Base ID from its URL, and make sure the target table has two single-line-text fields named “Title” and “Details”.
Tip: Cal.com lets you scope webhooks per event type — enable just BOOKING_CREATED if you only want new bookings, or add the others to track changes too.
Events you can forward
BOOKING_CREATED
BOOKING_CANCELLED
BOOKING_RESCHEDULED
Questions
Is my Cal.com Webhook Secret safe with ZestyGlue?
It's encrypted at rest with Fernet symmetric encryption before it ever touches disk, it's never logged, and it's never displayed again in the dashboard after you enter it — only a masked placeholder is shown.
Is this the same as Cal.com's built-in notifications?
No — Cal.com's own notifications are typically personal booking confirmations. This is a webhook-level feed you can route to a shared team channel in any of ZestyGlue's 8 destinations.
Does self-hosted Cal.com work the same way?
Yes, as long as your self-hosted instance can reach zestyglue.com over the internet to deliver the webhook.
Which Airtable plan do I need?
Airtable's free plan includes API access and is enough for ZestyGlue to create records — no paid plan required.
What happens if my ZestyGlue subscription lapses?
Events are silently dropped rather than causing errors on Cal.com's side — Cal.com never sees a failure response, so it won't retry aggressively or flag your webhook as broken. Your dashboard will simply stop showing new events until you resubscribe.
