# Track UTMs on Podia Checkout

## UTM attribution overview

Podia UTM Tracking Integration only records UTMs that land on the checkout URL at purchase time. UTM Grabber keeps them in cookies on your site. This page explains how to pass that data through before the customer pays.

### What to expect

Creator checkout links accept URL parameters.

### Steps

1. utm-out to Podia product URLs

### Append UTMs with utm-out

```
<a href="https://your-checkout-url.example/product" class="utm-out">Buy now</a>
```

UTM Grabber rewrites the link with cookie values. Details: [utm-out class guide](https://docs.utmgrabber.com/books/102-getting-started-for-handl-utm-grabber-v3/page/appending-utms-to-the-buttons-using-class-name-attributes-selectively).
