Handle clear WhatsApp cancellation requests
Start a Notis webhook workflow when a request arrives, then have Notis verify the chat context and matching Cal booking before cancelling it.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Cancel booking via uid
Cancels an existing and active cal.com booking using its unique identifier (uid).
Why this helps
Cancellation requests can sit in chat while the active booking remains on the calendar.
- Reduce delay between a cancellation request and calendar update.
- Check the conversation against current booking records.
- Route uncertain requests to a report instead of guessing.
Setup
Build it in a few focused steps.
- 1Connect 2chat and Cal once in the Notis portal.
- 2Create an automation and name it for cancellation requests.
- 3Tell Notis to verify a clear cancellation request in 2chat, find the matching active Cal booking, and cancel it only when the booking identity is unambiguous.
- 4Pick the Notis webhook trigger and choose where run reports should go.
- 5Test with one real example and review the result before relying on it.
Questions about this workflow
Will it cancel based on any mention of cancelling?
The instruction should require a clear request and an unambiguous booking match. Uncertain cases should be reported for review.
Can a cancelled booking be restored by this action?
The listed action cancels an active booking. The workflow should treat cancellation as consequential and avoid acting on unclear requests.
