Zcal Integrations and Webhooks is one of 3 APIs that [Zcal](https://apis.io/providers/zcal/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Webhook, Integration, and Automation. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

Outbound webhooks POST a JSON payload to a subscriber URL when a booking is created, rescheduled, or cancelled. Payloads can be verified with an optional HMAC SHA-256 signature via the x-zcal-webhook-signature header. Connectors such as Zapier and Make, plus native Zoom, Stripe, Google Analytics, and Meta Pixel integrations, extend automation without a public REST API.
