Track UTMs in Bookly Appointments

UTM attribution overview

Booking pages are a common leak in attribution. Bookly UTM Tracking Integration needs UTMs on the booking URL when the appointment is confirmed. UTM Grabber already captured them on your WordPress site. Here is how to carry them over.

Bookly runs inside WordPress, which is a good fit for UTM Grabber. Attribution still needs hidden fields on the booking form so the values save with the appointment.

Steps

Setup

1. Use Bookly custom fields or a small code snippet to add hidden inputs for utm_source, utm_campaign, gclid, etc.
2. UTM Grabber populates them when the customer opens your booking page
3. Check the appointment in Bookly admin to confirm fields saved

Add utm-out to any button or link that opens your Bookly UTM Tracking Integration scheduler. utm-out class guide.
