Build on ChronSync with API keys, the REST API, webhooks, and an embeddable booking widget — everything you need to integrate scheduling into your own app.
ChronSync is built to integrate. Use the REST API to read availability and create bookings from your own systems, subscribe to webhooks to react to scheduling events in real time, and embed your booking page directly in your site. Every request is authenticated with an API key scoped to exactly what your integration needs.
If you're new here, create an API key first, then explore the API. The pages below cover each task on its own.
Create an API key
Generate a scoped key in Settings and use it as a Bearer token to authenticate requests.
Set up webhooks
Receive signed event notifications when bookings, plans, payments, and waitlist entries change.
The ChronSync API
Authenticate, find your way around the REST resources, and open the interactive OpenAPI reference.
API scopes
The full list of scopes and preset bundles you can grant an API key.
Analytics and reports
What ChronSync analytics show — KPI cards, bookings over time, popular time slots, cancellation reasons, team performance, and revenue — plus how date range and scope work.
