Express Checkout API

The Express Checkout API is the Website Payments Pro alternative to standard PayPal

shopping cart processing.

IMPORTANT: For a full understanding of the complete details about how to use PayPal

Express Checkout, consult the PayPal Express Checkout Integration Guide.

The Express Checkout API consists of three distinct SOAP requests that you make at the three

integration points during a customer checkout:

1. SetExpressCheckout

2. GetExpressCheckoutDetails

3. DoExpressCheckoutPayment

IMPORTANT: All currency amount fields in the three Express Checkout APIs require that

the currencyID attribute be set to one of the supported currency codes. For

any one particular buyer’s checkout session, do not mix currencies either in

any single SOAP request or across SOAP requests. For example, do not set

currencyID to USD in one request and then to GBP in a later request for

the same buyer.
