Getting Started With Express Checkout

Implementing the Simplest Express Checkout Integration

The following diagram shows the Express Checkout execution flow, which uses the Sandbox

as the API server. The pages on the left represent your site.

The following steps match the circled numbers in the diagram. Perform the actions in each

step to test Express Checkout.

1. Invoke a form on your site that calls the SetExpressCheckout API on the Sandbox.

To invoke the API, set form fields whose names match the NVP names of the fields you want

to set, specify their corresponding values, and then post the form to a PayPal Sandbox server,

such as https://api-3t.sandbox.paypal.com/nvp, as shown in the following

example:
