title: integrating paypal check without leaving your site
body: <p>I want to integrate paypal in my website. But my requirement is, I dont want my customers to go into paypal site for payment. (I know it is not a secure way, but it is my requirements) Is there a way such that I can do credit card checks in backend using paypal APIs ?  If so, which method to be used? I want it for "singapore" country and SGD as currency.</p>
