Want to start a website where people can buy items and we will ship them to their address. Want to know how to implement online payments system where people can buy thru credit card , net banking, debit card. People will add items to cart and make the payment by credit card/net banking. website targets customers from india only as of now.
It should be like i take the order details and shipping address and redirect users to the payment gateway and after payment done will show them order confirmation on my website. how this communication between mywebsite and payment gate way works? plz suggest

Thanks in advance
