Term Description
SP-API The Selling Partner API (SP-API) is a suite of REST-based APIs that provides Amazon selling partners with programmatic access to their Amazon Seller Central account data. Among other things, data can be exchanged on listings, orders, payments, reports and more. The data integration with Amazon enables a high level of sales automation, which can help sellers grow their business. Additionally, the SP API can be used to create applications that help sellers manage their Amazon business. We have leveraged this opportunity to increase seller efficiency, reduce workload, and improve response time to customers by using the SP API. We use SP API data to connect to a seller's account in a secure way and import product details (prices, quantity, competitor list, etc.). The Selling Partner API is a modernization of Amazon MWS and includes all functionality previously available from Amazon MWS.
