How to modifi order total

[martinmolero]

I'm just arrived to prestashop development and I need some help.

 

I'm working whit a bank payment module and I need to modify the total amount of the order before sendding the payment to the bank platform (make a discount for this payment method).

 

My module is working (the bank is charging the disared amount) but this amount dont match with the order total cause I dont Know how to modify it from the module.

 

So, when the bank api response is sent to the shop I see an error payment cause the order total is 86.50 €, for example, and the paid amount is said to be 84,34 €.

 

Some one can help me, please?

a workaround would be to recalculate the value after the api response, or use a unregistered variable to send the regular price

Suppose the discount is 1%, and the order is 100eur

-send 99eur total to the api

-when you get the response, add the 1% (actually 1/99) back and compare that to the cart total

 

or b.

use a dummy variable in your request, most apis support that

api.php?token=xxxx&orderId=12&price=99&actualPrice=100

and in the response compare the actualPrice variable instead of the price one

This was what I made

How to make this one?

It doesn't work... the problem remain the same.
