Zcal

Zcal is a free scheduling platform for booking meetings via shareable scheduling links, meeting polls, and team pages (round-robin and collective). Zcal does not publish a general-purpose public REST API; programmatic integration is delivered through outbound webhooks (event.created, event.rescheduled, event.cancelled) and no-code connectors such as Zapier and Make, plus native integrations including Zoom, Stripe, Google Analytics, and Meta Pixel.

  description: 'Zcal does not publish a general-purpose public REST API. The only documented programmatic surface is outbound
    webhooks: Zcal POSTs a JSON payload to a subscriber URL you configure when a booking is created, rescheduled, or cancelled.
    The single item below is documentation-only and represents the shape of that outbound webhook payload for reference; it
    is NOT a Zcal-hosted endpoint you can call. Replace the URL with your own webhook receiver to test delivery.'
