Direct Payment API offers you direct credit card payment processing capability through PayPal. For credit card transactions, customers stay on your website as PayPal processes the payment in the background.

Note: Direct Payment API is not a stand-alone product. You are required to use Direct Payment API and Express Checkout together as part of the Website Payments Pro solution.
