NVP/SOAP Integration

Important: This integration method is Deprecated as of January 1, 2017. For new integrations, see the PayPal Express Checkout Integration Guide.

Express Checkout minimizes the number of steps customers must complete when they check out. It's designed for merchants who don't have an Internet Merchant Account for processing credit and debit card payments. With Express Checkout, your buyers can pay with PayPal or credit and debit cards.

The In-Context PayPal Express Checkout helps improve conversion rates with an easier way to pay online. The simplified design speeds buyers through payment in as few as one or two clicks — without leaving your website — for a secure and seamless check out. A consistent experience for computers, tablets, and smart phones gives customers a trusted way to pay across different devices.

Note: On Macs and PCs, the In-Context Checkout window keeps the merchant website in view while providing customers with a streamlined and tightly-integrated checkout experience.

Smart phones and tablets display an optimized full-page checkout window

You can see a demo of In-Context Checkout on the PayPal Demo.

The In-Context Checkout flow
