Steps

1. Zapier/n8n: form submit to Slack with UTM fields in message body

Slack Webhook Notifications with Full UTMs

UTM attribution overview

This walkthrough covers sending full UTM Grabber data from Slack UTM Tracking Integration to Zapier, Make, or your own webhook. Handy when you need gclid, fbclid, first-touch fields, or custom params alongside the lead or order.

Start with the main Slack UTM Tracking Integration setup guide if you have not wired hidden fields or checkout links yet.

When a webhook makes sense

Native fields in Slack 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>

Quick Zapier / Make checklist

1. Create a Catch Hook trigger and copy the URL
2. Run a test conversion with UTMs in the landing URL
3. Confirm gclid, utm_source, and email (if present) show up in the payload
4. Map fields into your CRM or spreadsheet
