Amazon Marketplace Web Service

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.

Amazon MWS Scratchpad

Amazon MWS Scratchpad is an application that enables you to easily submit query requests using any Amazon MWS API section. You can indicate the API section, the operation, and any required and optional parameters from the Amazon MWS Scratchpad user interface.
