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 using 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 the Selling Partner API, you can:

  • Set up an OAuth authorization workflow that selling partners initiate from the Amazon Partner Network 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 be able to create a SP-API application that can be authorized by a selling partner from any region or marketplace. You need only one set of developer credentials (your AWS access key ID and AWS secret access key) to make calls to any SP-API endpoint, as long as the endpoint is for the same region as the selling partner who authorized your application.
