Accessing Your MWS Amazon Seller ID & AuthToken

Amazon Marketplace Web Service (Amazon MWS) is a secure environment that uses signatures for authentication to access the Amazon MWS API. Providing Synccentric with MWS keys allows Synccentric to make API requests on the sellers behalf for customized and quicker solutions. To be eligible to register for Amazon MWS, you must have an active Amazon Professional selling plan.
