This two-in-one gateway add-on allows you to accept payment through PayPal Payments Proand PayPal Express Checkout. When purchasing downloads through PayPal Pro, users enter their credit card details during the checkout process and never leave your site, resulting in a better experience for the user, and more successful conversions for you. When checking out with PayPal Express, the user experience is very similar to PayPal standard, except it is more secure.
