Conversion track for Woocommerce

Hi,

We were asked by client to add conversion pixel code on the backend for them to track sales and marketing return on ads investment.

They sent this link: https://www.facebook.com/business/help/262326191335941

However, I have no idea what to replace the value of final_price_without_currency see: https://prnt.sc/v7932w

They said the dynamic value depends on the platform we’ve used which is Woocommerce.

Do you any idea for this as I already searched the net but there’s no correct example what to set on the dynamic value.

Thank you.
