Our webhook subscription will inform you when invitees book, cancel, or reschedule events. While the process is completely manual, you can use the values within the webhook payload to trigger follow up actions in the internal or custom-built apps you or your team use. If you want to trigger automations without any development work, learn more about our integration with Zapier, which connects Calendly to apps you use daily.
  • When an event is scheduled, the invitee.created webhook is triggered.
  • When an event is canceled, the invitee.canceled webhook is triggered.
  • When an event is rescheduled, both the invitee.created and invitee.canceled webhooks are triggered.
To learn more about creating a webhook subscription, see receive scheduled event data in real time with webhook subscriptions.

Webhook payload values

To create your own follow up actions, use the values located within the webhook payload. Some that may be helpful include:

  • "``event``": "``invitee.canceled``" is triggered when an event is canceled

​
The status value

The status value identifies if the invitee is attending or not attending the scheduled event
  • "``status``": "``active``" indicates that the invitee will attend the scheduled event
  • "``status``": "``canceled``" indicates that the invitee will not attend the scheduled event

​
The canceled value

The canceled value identifies if the event was canceled
  • "``canceled``": ``false indicates that the event has not been canceled
