Data integration with Amazon MWS API enables third-party tools to help sellers scale their presence on Amazon and improve customer response time. This integration enables them to programmatically retrieve business reports, make changes to product listings, and more. All sellers need to do to facilitate this is provide access to the third-party tool.

This is easily done for fully integrated third-party tools such as Intentwise. Sellers simply need to enter their login credentials to allow the tool to obtain API authentication.

Where there is only partial integration between the platform and the Seller Central for Amazon MWS API access, you will need to do the following.

Steps to Provide Amazon MWS Access to Partially Integrated Third-Party Tools

Login to Seller Central with Amazon credentials  and navigate to “User Permissions” under “Settings”

MWS login










In the “Third-party developer and apps” section click on “Visit Manage Your Apps”

MWS developers and apps

Now click on “Authorize new developer”

MWS API authorization







When you reach the screen below,  Put the Developer’s Name as “Intentwise” and Developer ID as 952779673474

Once you have entered the details click on the “Next” button.
