We’d love a supported way to track when a visitor successfully books an inspection through Online Scheduler V3 embedded on our website.

This would help inspection companies understand which advertising campaigns lead to actual bookings. Our immediate use case is OpenAI Ads conversion tracking.

Ideally, ISN could provide:

A documented notification to the website (postMessage callback) or a server-side webhook after a booking is successfully saved and scheduled.

A unique order or event ID to prevent counting the same booking more than once.

An indication that the booking originated from the Online Scheduler.

A supported way to preserve an ad-attribution identifier through the booking process.

The notification should only fire after a successful save—not when someone selects an appointment, clicks a button, abandons the scheduler, or encounters an error. We mean completion of the booking, not completion of the inspection.

The notification should avoid including customer personal information. Documentation and an example integration would be very helpful.

Thanks for considering this! We’d be happy to share more about our setup or help test a supported solution.
