Most marketplaces disclose their APIs so that eCommerce applications and software solutions can access e-store data. Businesses, for their part, must integrate with APIs in order to gain access to the previously mentioned store data. APIs serve as a link between your system and the databases of the marketplace. As a result, marketplace integration is a must for gaining access to the client’s store data.
Selling Partner API (SP-API) is a modernized set of REST APIs that adhere to the standards that today’s developers expect while making the migration from their legacy Amazon Marketplace Web Service (Amazon MWS) APIs as painless as possible. This suite will include all of the features found in Amazon MWS, as well as over a dozen brand new APIs, including vendor APIs. All registered developers in the world can now use the SP-API.
