Pass UTMs into OnceHub Scheduling Links

UTM attribution overview

Booking pages are a common leak in attribution. OnceHub 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.

ScheduleOnce/OnceHub bookings accept tracking params on the booking URL.

Steps

1. Append handl_utm to scheduling page URLs

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

When a webhook makes sense

Native fields in OnceHub UTM Tracking Integration often stop at basic UTMs. A webhook lets you push everything UTM Grabber stores without trimming values or losing click IDs.

Thank-you page script

Paste this on your confirmation page. Swap in your Zapier or Make hook URL.

<script>
var qvars = {};
window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m, key, value) {
    qvars[key] = decodeURIComponent(value.replace(/\+/g, ' '));
});
qvars = Object.assign({}, (typeof handl_utm !== 'undefined' ? handl_utm : {}), qvars);
setTimeout(function() {
    var data = new URLSearchParams(qvars).toString();
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open('GET', 'https://hooks.zapier.com/hooks/catch/YOUR_ID/YOUR_KEY/?' + data, true);
    xmlHttp.send(null);
}, 1000);
</script>
