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.

Connecting your Amazon Store to Shipwire is easy. The sell tool uses the Amazon MWS API connection. NOTE: Your Amazon account must allow for API access (not available for individual accounts, you need a Pro account or better). If you are unsure of your account type, contact Amazon.
