# Track UTMs on Drip Forms

## UTM attribution overview

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

### Drip UTM Tracking Integration and UTMs

Drip supports custom fields on subscribers. Capture at signup.

### Steps

1. Map hidden fields to Drip custom fields via form action or API

### 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>
```
