Mobile Express Checkout

Important: The information in this topic is Discontinued because Express Checkout now supports mobile devices by default. You no longer need to perform any additional integration steps or programming to take advantage of Express Checkout's mobile checkout flow. For more information, see the Express Checkout Integration Guide.

Mobile Express Checkout enables merchants to simplify checkout for customers using mobile devices. PayPal Mobile Express Checkout optimizes the pages for smaller mobile screens and mobile keyboards. If the merchant has already integrated Express Checkout, they can add Mobile Express Checkout to their website with minimal programming changes.

How it works

  1. On a mobile device, the customer selects an item and chooses to pay with a PayPal account or a debit or credit card.
  2. The customer logs in to their PayPal account and clicks Checkout with PayPal from the shopping cart, reviews payment and shipping details on a mobile PayPal page, and commits to the payment.
  3. To pay with a debit or credit card, the customer clicks the pay with card link on the PayPal log in page and enters payment and shipping information.
  4. The order confirmation appears on the merchant’s mobile site.

Why use Mobile Express Checkout

Implementing Mobile Express Checkout enables merchants and developers to:

  • Provide payment pages to customers optimized for faster checkout using mobile devices like the iPad, iPhone, and Android devices.
  • Eliminate the need for customers to enter personal details including shipping, billing, or payment information.
  • Provide a streamlined checkout experience for mobile browsers.
  • Process customers’ payments on PayPal’s secure site.
  • Offer guest checkout to customers. Customers can pay using a debit or credit card on the merchant’s mobile website without logging in to PayPal or creating an account.
  • Accept recurring payments. These allow customers to give pre-approval for future payments and to make subscription-based payments for fixed or variable amounts.
  • Add Mobile Express Checkout to current implementations of Express Checkout with minimal effort.
  • Automatically return customers to the merchant’s website to complete the order.

Supported devices and browsers

Mobile Express Checkout supports most mobile devices in use today. If we cannot support a device, we fall back on the standard PayPal experience.
