CFWebstore includes two different types of PayPal integration: PayPal Standard which is the original PayPal transaction method which redirects the customer to the PayPal site at the end of the checkout process, completes the payment on their site and uses IPN behind the scenes to finish the order. The newer PayPal checkout is PayPal Pro. This includes a PayPal transaction method that behaves similar to a normal gateway where the customer stays on your site and completes a credit card order from your checkout area. However, PayPal also requires that merchants that use PayPal Pro include PayPal Express integration. This is a payment method where the customer leaves your site at the beginning of the checkout process, selects their address and payment method at PayPal, and then returns to your site to complete the order. Both have their advantages and disadvantages both for the user and for the merchant. Customers that are regular PayPal users like not having to re-enter their address and payment information, but it may be confusing to some customers to leave and then return to the site. For merchants, it has the disadvantage of hiding all the billing address information, but Express has shown to be more reliable for most as it does not have the same possibility of a payment at PayPal completing, but nothing returning to your site. So many merchants that use Standard have considered switching to using Express for the better experience for the customer and greater reliability. So in this article, I'll show you how you can do this on version 6 of CFWebstore.
