Cancel an Active Calendly Event from an HTTP Request
An external system can send a request to Notis when an event should be cancelled. Notis uses the supplied Calendly event UUID and optional reason.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Cancel event
Permanently cancels an existing, active scheduled event by its `uuid`, optionally providing a `reason`, which may trigger notifications to invitees.
Why this helps
When a meeting must be cancelled, delays between a request and the calendar update can confuse everyone involved.
- Start cancellation from an external HTTP request.
- Use the scheduled event UUID to identify which event to cancel.
- Include an optional cancellation reason.
Setup
Build it in a few focused steps.
- 1Connect Calendly once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to cancel the existing active Calendly event identified by the incoming request and include a reason if appropriate.
- 4Pick the Notis webhook trigger and choose where run reports go.
- 5Test by sending one real example request for a valid scheduled event and check the run report.
