Cashback code implementation

http://www.bb-spices.de/ has made a contract with a Cashback Solutions program.
Thisfor I need to implement a specific Code on a Redirect page for gathering the TDUID out of the domain:


Furthermore I need to implement the Tracking-Pixel which contains the TDUID, organizationID, eventID, orderNumber, orderValue and currency:


So how exactly am I able to implement those given codes and how am I able to Access the variables of the shop in order to use them for those codes (orderValue, orderNumber).
I’d be grateful for your help!

Sincerely yours
Tobi
