The GFS Amazon Connector requires you to create an Amazon Marketplace Web Service (MWS) credential. You can sign up or manage your Amazon MWS by using the following links (varies by region, some examples are below). https://developer.amazonservices.co.uk (for Amazon UK) https://developer.amazonservices.com (for Amazon US).
You must have a valid Amazon Seller Professional Account to sign up to this service. After signing in with your seller account credentials, you must choose the option “I want to access my own Amazon seller account with MWS.” Once you accept the license agreement, a page will be displayed where you can copy your developer credentials (Access Key ID, Secret Access Key, Seller ID).
An example of the page that has this information is below.
You need to provide this information to the GFS IT Support team to configure the Connector to download and update your orders, as well as ensure that this is working prior to your go-live date with the Connector.
