what are the variables for the amount and transaction in Prestashop 1.4.8.2?

[cft100]

Hi,

 

I'm trying integrate Pshop with third party affiliate software and need to be able to identify two variables in Pshop to do this; the amount (of the sale) and the transaction (I guess this would be an ID of some sort).

 

I use Paypal to process credit card transactions, and therefore need to be able to identify the amount and transaction id of a sale that was referred by an affiliate.

 

I think this is a simple question (not a developer myself), can someone please help?

 

For ref, the Pshop site is xede.fr/store

 

Many thanks.
