Tracking Code Structure

Thank You Page

On the thank you page, JavaScript is generated that:

1. Loads the Heureka SDK
2. Authenticates using the public key
3. Sets the order ID
4. Adds products (ID, name, price, quantity)
5. Adds shipping and fees
6. Sets the total price and currency
7. Sends the data

Product Page

On the product page (is_product()), only the Heureka SDK is loaded for tracking product views.
