# Track UTMs on Tally Forms

## UTM attribution overview

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

### Tally UTM Tracking Integration and UTMs

Tally accepts hidden fields and URL parameters. Embed on WordPress with UTM Grabber active.

### Steps

1. Add hidden fields in Tally
2. Prefill via URL or JS from handl\_utm

### 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>
```
