Regarding PayPal

Question

Hi,

I hope you all are doing well.

We are using paypal system as payment gateway in our site and we have only single product so we mentioned item price in paypal itself.

So My Question is: How we can change that item price through our code using asp.net with c#. We do't want to go in paypal system again and again if we want to change the price. Please reply ASAP. Thanks

Regards
