Setting up PayPal Express Checkout

PayPal is a popular payment system worldwide that offers online shoppers an alternative checkout option called PayPal Express Checkout. Using this option, customers can add items to their shopping carts, check out on a secure PayPal payment page, and automatically return back to the store.

In order to enable a PayPal Express Checkout button in your online store and make it work to accept payments from your customers, follow our instructions provided below. Remember that only customers who have a personal PayPal account will be able to use this checkout option.

When that button is clicked on, information about products added to the cart is passed to PayPal, and customer is redirected to the PayPal website to pay for the order.
