Hi!

I hope that someone could help me with the following issue.

I’m trying to pass information at checkout/thankyou page using a script.Getting all values except product_name.
basically its for affiliates.

script is :

These are the variables :-
adv_sub1={{billing_address.city}}
order_id={{checkout.order_name}}
product_name=???
sale_amount={{checkout.total_price | money}}

How to get product_name using this script?

Any idea or alternative solution to pass this value? I’ll really appreciate any advice.

Thank you very much!
