Setting Up Your Amazon Integration


Detailed below is an overview of the process for setting up integration between Gateway OMS and the Amazon Marketplace

To get started you will need

1. Amazon Seller Account - register below if you do not have an account 

2. Amazon MWS Key / Token

An MWS token is needed to be able to interact with Amazon. The user token represents an authorization for OMS to access Amazon data on behalf of an Amazon User. 

  • Go to
  • Click the Sign up for MWS button.
  • Log into your Amazon seller account.
  • On the MWS registration page, click the button for I want to give a developer access to my Amazon seller account with MWS.
  • In the Developer's Name text box, type Custom Gateway. This doesn't need to be the exact name; it is merely for your reference in the future.
  • In the Developer Account Number text box type: 9133-2972-0047
  • Click the Next button.
  • Accept the Amazon MWS Licence Agreements and click the Next button.
  • Copy your account identifiers (Seller ID, MWS Authorization Token and Marketplace ID) as your third-party developer needs them in order to programmatically access your Amazon seller account.
  • Paste your account identifiers into an e-mail and send it to your project manager. It is also a good practice to print this page and save it in a safe place.

3. Confirm sales regions
