We're currently moving our shopping platform from Yahoo (terrible) to CS-Cart (yippee!)
We are using FirstData Linkpoint as our payment processor.
At checkout, we noticed that it takes the user to an external page at FirstData to process the credit card information. Is there anyway that this can just be integrated within CS-Cart so it keeps the customer on our site? It just seems a little bothersome.
This wasn't the case on yahoo, everything was integrated and went through smoothly.
In order not to redirect a customer to external site, you should use LinkPoint API payment method in CS-Cart.
