Track UTMs via Checkout Success Page Webhook

UTM attribution overview

Send full HandL UTM Grabber attribution from Stripe UTM Tracking Integration to Zapier, Make, or any webhook, including click IDs, first-touch fields, and custom parameters.

For the primary integration setup, see the main Stripe UTM Tracking Integration guide.

When to use webhooks

Use this when you need to send all UTM Grabber parameters to a CRM, spreadsheet, or ad platform. That includes gclid, fbclid, msclkid, first-touch fields, and custom parameters that may not fit into native Stripe UTM Tracking Integration fields.

Thank-you page webhook script

On your thank-you or confirmation page, merge URL parameters with handl_utm and POST/GET to your webhook:

<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>

See Triggering Zapier on Thank you Page for the full walkthrough.

1. Create a Catch Hook trigger in Zapier or a Custom Webhook in Make
2. Paste the webhook URL into the script above
