What is Express Checkout?
Express Checkout provides a seamless checkout experience via an API-based integration for
buyers who want to use their PayPal accounts or Credit Cards (even without logging into a
PayPal account). Buyers select their payment methods and shipping information on PayPal,
then return to your website to finalize their purchases. Express Checkout allows your buyers
to complete transactions in very few steps. It eliminates one of the major causes of
checkout abandonment by giving buyers all the transaction details at once, including order
details, shipping options and tax totals. Use Express Checkout to complement your existing
payment solutions and to do the following:
 Accept payments from buyers using credit cards or from any PayPal account.
 Reduce checkout abandonment by eliminating the need for customers to
reenter personal information, including shipping, billing and payment
information.
 Keep customers on your site after they complete their transactions.
How Express Checkout Works
Buyers use Express Checkout to pay you on PayPal's secure site and return to your site to
complete the transaction. When buyers complete their purchases, your website makes an
API call (unseen by the customer) to PayPal to request payment. The payment transaction
is initiated and PayPal sends buyers email receipts for the payments.
