How to calculate discount amount for different currencies.
I have to know currency exchange api in hikashop and discounted price calculation base on currency.
Pls discuss for this topic.

Hello,
I don't think that you you'll be able to restrict your products regarding the currency of your shop, but you can set the value of that discount on a currency, and that value will be converted regarding your shop current currency.
