About Selling Partner API (SP-API)

• The Selling Partner API (SP-API) is a modern suite of REST APIs that uses the standards that today’s developers expect while making migration from our legacy Amazon Marketplace Web Service (Amazon MWS) API as simple as possible.
• The SP-API includes all the functionality available in Amazon MWS plus many new APIs; including vendor APIs. The SP-API is available to all registered developers worldwide.
• Applications using SP-API can help sales partners grow their business by increasing sales productivity, reducing labor requirements, and improving response time to customers.

Selling Partner API (SP-API) Key Features

Using the Seller API, you can:

• Set up an OAuth authorization workflow that is initiated by a selling partner from the selling partner app store detail page or from your own website.
• Generates an SDK that helps you with LWA token exchange and authentication.
• Test your application by invoking a sandbox environment.

Global Applications

You only need to register as a developer once in the region and market of your choice, and you can create SP-API applications that can be authorized by sales partners in any region or market. You only need one set of developer credentials (your AWS Access Key ID and AWS Secret Access Key) to call any SP-API endpoint as long as the endpoint is in the same region as the sales partner who authorized your application.
