}

window.addEventListener('message', event => {

if (event.data.handl) {

	merged = event.data

	for (v of vars){

		if (merged[v] != undefined){

			console.log(v, merged[v])

Send OptimizeLeads UTMs via Zapier or Webhook
UTM attribution overview This walkthrough covers sending full UTM Grabber data from OptimizeLeads 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 OptimizeLeads guide . When a webhook makes sense Native fields in OptimizeLeads 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);
