# Tracking

{% hint style="info" %}
If you are using any of Firework e-commerce app/extension/cartridge (like Shopify, Magento, SFCC etc.), you do not need to implement the purchase tracking manually. It is handled by the app/extension/cartridge. Please refer to the purchase tracking section of the e-commerce platform integration doc for more details.
{% endhint %}

Firework provides a way to attribute tracking events, such as "purchase", with additional properties like value and products

### Embed Analytics Script Tag

Make sure the Firework script is injected into `<header>` at all your pages where you want to call the tracking function. Usually, it's the header of the checkout page.

```
<script async type="text/javascript" src="//asset.fwcdn3.com/js/analytics.js"></script>
```

Call the relevant push event whenever it is needed.
