Send Mailchimp for WordPress UTMs via Zapier or Webhook

UTM attribution overview

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

For the primary setup, see the main Mailchimp for WordPress guide.

When a webhook makes sense

Native fields in Mailchimp for WordPress 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>

Full pattern explained in Triggering Zapier on Thank you Page.

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
