Pro Sites payment gateway support for ZAR currency

I am using Pro Sites, can I use it for users to activate their packages with the coupon instead of the payment. Because the payment gateways that are on Pro Sites does not support my currency (ZAR)

Please see attached. I have this payment gateway. I can add the code to manual payment. but where do I get those two URL's. Is there any workaround for this payment gateway to work with Pro Sites.
