Why I might need to know my Amazon Merchant Token?
Keeping your MWS auth token updated and connected to your tool4seller account is very important. If your MWS auth token expired or even revoked, in order to make sure you can use the tool4seller’s tools properly, you will need to re-establish the access to authorization. Then you will need the Amazon MWS Auth Token ID.
