Integration
You can test your Express Checkout integration in the Sandbox.

values for API operations from these forms. You can use this strategy for your initial testing;

containing actual code.
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.
