Use SiteManager with Amazon MWS

Amazon Marketplace Web Service (Amazon MWS) is an integrated web service API that helps Amazon sellers to programmatically exchange data on listings, orders, payments, reports, and more. Data integration with Amazon enables high levels of selling automation, which can help sellers grow their business. By using Amazon MWS, sellers can increase selling efficiency, reduce labor requirements, and improve response time to customers. There are no fees associated with Amazon MWS, but to use the Amazon MWS API you must have an Amazon MWS-eligible seller account and you must register to use Amazon MWS.
