What is the Selling Partner API?

The Selling Partner API (SP-API) is a REST-based API that helps Amazon selling partners programmatically access their data on orders, shipments, payments, and much more.

Applications that use the SP-API can increase selling efficiency, reduce labor requirements, and improve response time to customers, helping selling partners grow their businesses.

Key features

With SP-API, you can:

• Set up an OAuth authorization workflow that selling partners initiate from the Selling Partner Appstore detail page or from your own website.

• Generate an SDK that can help you with LWA token exchange and authentication.

• Test your applications by making calls to a sandbox environment.

Global applications

You only need to register as a developer once, in the region and marketplace of your choice, to create an SP-API application that can be authorized by a selling partner from any region or marketplace.
