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.
