Testing

In a sandbox environment, emails use the fake provider, so nobody's mailed, and nothing's charged. Everything else works as it does live, including the double-booking guarantee and hosted pages.

Simulated calendars

Connect a calendar nobody hosts, and set its busy times yourself:

await coss.scheduling.calendars.connect("doctor_482", { provider: "simulated" });

await coss.scheduling.calendars.setSimulatedBusy("doctor_482", {
  intervals: [{ start: "2027-01-04T15:00:00Z", end: "2027-01-04T16:00:00Z" }],
});

You can also connect real calendars in a sandbox, to see the consent flow.

Webhooks

Test your handlers with coss trigger scheduling.booking.confirmed, or coss.webhookEvents.test({ type: "scheduling.booking.confirmed" }).
