Hi @carloskris,
First of all sorry for the inconvenience caused to you. I assure you that you’ll receive the best solution from us.
If I understood you correctly, do you want that if multiple products in the cart and the discount should be applied just once?
If a payment gateway-based discount is set using our plugin(not the coupon code) in multiple products and if these products are added to the cart together the discounts set for each product will get added to the cart: https://prnt.sc/9n4Kt4vTNauR
Do you want that this discount should be applied once? If yes, I’ll ask our development team to find out the solution for this problem.
Kindly confirm the case.
