What is Amazon MWS?
Amazon Market Web Services (MWS) is an integrated web API that gives access to information on Amazon Seller Central. This API grants access to various bits of information associated with a Seller Central account and updates based on activity on the same account.
Connecting to the Amazon MWS is crucial to automate processes with your Amazon Seller Central Account. Much of the manual work done on a seller account can be automated if the API and subsequent communication (or other) systems involved are configured to automate the process for you.
