# Add Privatus Analytics to WooCommerce

> Add cookieless analytics to a WooCommerce store, then track each purchase with its total and currency from the thank you page without order details.

WooCommerce runs on WordPress, so you add the snippet the WordPress way.
[WordPress](/docs/install/wordpress) lists the options, including a
child theme hook and the WordPress plugin.

```html
<script defer src="https://privatusstats.com/js/pa.js" data-site="pa_YOURSITEID" data-modules="engage,auto,vitals,clicks,ask"></script>
```

The WordPress plugin tracks WooCommerce purchases for you. It is free in
the WordPress plugin directory. See
[WordPress](/docs/install/wordpress#with-the-plugin) for how to install it.

## Purchases without the plugin

WooCommerce runs the [`woocommerce_thankyou`](https://woocommerce.github.io/code-reference/hooks/hooks.html)
action on the order received page and passes it the order id. In a child
theme's `functions.php`, use the order only to read its total and currency:

```php
add_action( 'woocommerce_thankyou', function ( $order_id ) {
    $order = wc_get_order( $order_id );
    if ( ! $order || $order->get_meta( '_privatus_tracked' ) ) {
        return; // count each order once, even if the page reloads
    }
    $order->update_meta_data( '_privatus_tracked', '1' );
    $order->save();
    printf(
        '<script>window.addEventListener("load",function(){privatus.track("purchase",{revenue:%s,currency:%s});});</script>',
        wp_json_encode( (float) $order->get_total() ),
        wp_json_encode( $order->get_currency() )
    );
} );
```

`revenue` and `currency` are read as the event's revenue. See
[Revenue](/docs/events/revenue). Never send the order id, names or email
addresses as properties.

## Caching plugins

Exclude `pa.js` from "combine", "defer JS" and "delay JS" features. See
[Caching plugins](/docs/troubleshooting/caching).
