# MemberMouse UTM Tracking Integration

Track UTM parameters and campaign attribution with MemberMouse UTM Tracking Integration and HandL UTM Grabber on WordPress.

# Track UTMs on MemberMouse Checkout

## UTM attribution overview

HandL UTM Grabber stores campaign data in the browser. This guide shows how to get that data into MemberMouse UTM Tracking Integration using hidden fields on your WordPress forms.

### MemberMouse UTM Tracking Integration and UTMs

Membership checkout should carry campaign source. Hidden fields on MM checkout forms.

### Steps

1. Add custom fields in MemberMouse
2. Map to UTM Grabber param names

### Prefill hidden fields

UTM Grabber fills inputs whose `name` matches a tracked parameter. Field names must line up exactly. List of params: [Native WP Shortcodes](https://docs.utmgrabber.com/books/102-getting-started-for-handl-utm-grabber-v3/page/native-wp-shortcodes).

```
<script>
jQuery(document).ready(function() {
    if (typeof handl_utm === 'undefined') return;
    handl_utm_all_params.forEach(function(param) {
        var val = handl_utm[param] || (typeof Cookies !== 'undefined' ? Cookies.get(param) : '');
        if (val) jQuery('input[name="' + param + '"]').val(val).change();
    });
});
</script>
```

# Send MemberMouse UTMs via Webhook

## UTM attribution overview

This walkthrough covers sending full UTM Grabber data from MemberMouse 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 MemberMouse UTM Tracking Integration setup guide](https://docs.utmgrabber.com/books/membermouse-integration/page/rack-s-on-ember-ouse-heckout) if you have not wired hidden fields or checkout links yet.

### When a webhook makes sense

Native fields in MemberMouse 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
