SKU

1/ Sorry, I meant at the script level. So at this point, the SKU is correctly integrated into the cart page script.

2/ For this variable product, once the product is added to the cart and on the cart page, the SKU is properly populated:

<script type="text/javascript" id="tracktastic-matomo-cart-tracking-js-extra">/* <![CDATA[ */var tracktasticCartData = {"items":[{"sku":"121248","name":"\u062f\u0648\u0686\u0631\u062e\u0647 \u06a9\u0648\u0647\u0633\u062a\u0627\u0646 SCOTT Scale 965 2024","category":"","price":"129000000","quantity":1}],"cartTotal":"128970000"};/* ]]> */</script>

=> On the product page, the SKU is empty because it is not generally assigned; it is only populated variation by variation at the cart stage.

3/ For the “Order Confirmation” page, it is normal that no script is present; these scripts are included on the following pages: product page, product category page, cart, and once the order is confirmed.

4/ In your report “E-commerce > Products > Product Code,” are SKUs showing up correctly? On my end, the test I just repeated was successful (with a variable product).

Ok, so the extension script seems to be correctly in place; however, the SKUs are not showing up in the Matomo interface.

Could you please check your browser console? I see the following error:
“Refused to load the script ‘https://<MATOMO INSTANCE>/matomo.js ‘ because it violates the following Content Security Policy directive: “default-src ‘self’ ‘unsafe-inline’ ‘unsafe-eval'”. Note that ‘script-src-elem’ was not explicitly set, so ‘default-src’ is used as a fallback.”
