Getting started with webhooks

Calendly has an open API that supports webhooks. With the v2 API, you can build a webhook to receive real-time Calendly meeting data at a specified URL, when an event is scheduled or canceled. 

Specifically, you can subscribe to:

  • Invitee Created Events to receive notifications when a new Calendly event is scheduled
  • Invitee Canceled Events to receive notifications when a Calendly event is canceled
  • Routing Form Submissions to receive notifications when a user submits a Calendly routing form (whether an event is scheduled or not)

How to create a webhook

To create a webhook subscription, you will need to authenticate with either a personal access token or an OAuth application. For more ways to use the Calendly API, view Calendly's API Use Cases

For more information on how to create a webhook subscription, please visit our Developer Portal

Once you've created a webhook

Once you've created a webhook, event data will be received at the endpoint you've specified. For sample payload data, view Webhook Payload.

How to delete a webhook

To delete a webhook subscription, refer to Delete Webhook Subscription


If an admin within your organization creates webhooks and later has their role demoted, or is removed from the organization, those webhooks remain active. You will need to delete them if necessary.
