Callbacks & Events

How the widget notifies your page about bookings, errors, and closes.

The widget exposes three callbacks via init() (and open()):

  • onSuccess(data) — a booking completed successfully.
  • onError(error) — something recoverable went wrong.
  • onClose() — the modal was closed (modal mode only).

Each has its own page with the exact payload shape and common patterns.

onSuccess

What you get, and how it differs by system type.

onError

Error shape and when it fires.

onClose

Detecting when the patient dismissed the modal.

Analytics recipes

Tracking conversions with Google Analytics, GTM, or Mixpanel.

Auto-detection fallback chain

How the widget decides which system type to render.

onSuccess

Fired when a booking completes. The payload shape depends on the system type.
