Customer Currency not passing to Payment Gateway

Dear All,

I am integrated PayU payment gateway in the Nop3.9, and in my website there are 8 currencies enabled and INR is the primary currency.

The problem, I have facing is, while going to PayU payment gateway its showing the primary currency and amount instead of customer selected currency and amount.

Please help me to solve this issue and let me know where I went wrong.

Payments are always processed in the primary currency. What you want to do would require customization work.
