How do I connect SmartPrice to Amazon MWS?

To start repricing, you must authorize eComEngine's Seller Central developer account to access your Amazon seller account through MWS: a secure API connection.

This authorization is easy to set up and ensures that you can easily control tool access to your Amazon data.

How do I connect?

When you first create your SmartPrice account, you will be required to connect to Amazon MWS. There are two possibilities:

  • You already have an eComEngine account with current MWS authorization: if so, just select your store from the drop-down. We will use your existing connection!

  • You do not already have an eComEngine account, or your current MWS authorization has expired: follow the steps below to connect to MWS.


  1. Enter your store name and click "Connect to Amazon"smartprice_signup_step_3
  2. A new window will open and direct you to log into Amazon. Log in, making sure you are using the correct Amazon account and have sufficient user permissions to make changes.smartprice_connect_to_mws_edited
