I have a online shop and I am selling art items to customers from all countries. Now, I am integrating my payment gateway into the website. The integration is done perfectly but there is an issue in the currency conversion.
My base shop currency is in AED and bank account in Dubai is in AED currency but I have an option in the website to allow customers select their own local currency and pay in their own local currency but there should be a currency conversion step in the back ground where to send the AED to the payment gateway and USD to paypal instead of any other currencies.
Moreover, I will provide the customers the option to pay via paypal but paypal dont accept AED so we need to convert the AED or any other selected currency by the customer to USD so paypal accept it.
One more thing is that I need to add certain percentage to the checkout order if the customer selected paypal (4%) or credit card via the payment gateway (5%).
Please let me know if you can help in these three points.
