Once a customer places an order, you might want to know if such order contains a given product ID. you can use this for tracking purposes, redirect to a custom thank you page or run your custom functions.

Either way, checking this is quite simple thanks to the “woocommerce_thankyou” hook which runs on the order received page. Enjoy!
