Express Checkout User Interface

Requirements

Your Express Checkout integration must conform to PayPal’s requirements for button use and

placement. You must use only buttons hosted on PayPal and place them on your checkout and

payment pages.

Express Checkout Flow

To implement Express Checkout, you must offer it both as a checkout option and as a payment

method. Typically, you initiate the Express Checkout flow on your shopping cart page and on

your payment options page.

You add Express Checkout to your existing flow by placing the Checkout with PayPal button

on your Shopping Cart page and by placing the PayPal mark on your Payment Methods

page. The following diagram shows the complete flow:
