Calendly Webhook API is one of 14 APIs that [Calendly](https://apis.io/providers/calendly/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include Event, Notification, Scheduling, and Webhook. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

The Calendly Webhook API enables developers to receive real-time notifications when scheduling events occur in Calendly. By creating webhook subscriptions, applications can automatically receive data whenever invitees schedule, cancel, or reschedule meetings. This eliminates the need for polling the API and allows for event-driven integrations that respond immediately to changes in scheduling activity.
