# Track UTMs via Thank-You Page Webhook

## UTM attribution overview

Send full HandL UTM Grabber attribution from Easy Appointments UTM Tracking Integration bookings to Zapier, Make, or your CRM using a custom confirmation page and webhook.

Primary setup: [Easy Appointments UTM integration](https://docs.utmgrabber.com/books/easy-appointments-integration/page/easy-appointments-utm-integration)

### Custom confirmation redirect

Point your booking tool at a WordPress thank-you page after the appointment is confirmed. Include the customer email in the redirect URL when the tool supports it.

### Webhook script on thank-you page

Use the merge script from [Triggering Zapier on Thank you Page](https://docs.utmgrabber.com/books/zapier-integration/page/triggering-zapier-on-thank-you-page) to combine URL parameters with `handl_utm` and send the full payload to your webhook.

### Verify the payload

Book a test appointment from a page with `?utm_source=booking-test`. Check that utm\_source, gclid, and email (if passed) arrive in Zapier or Make.
