You can create your Amazon Product Advertising API directly on the Amazon Associates Program website. However, affiliates must have generated up to 3 sales before they can create credentials. Follow the steps below to create your Amazon API credentials:

Click on “Tools.”

Select “Amazon Product API” from the drop-down menu.

If you do not have credentials already, click on “Add Credentials.”

Click on ”Download Credentials.” Make sure you download the credentials while you are still on the page because you can not view the credentials again after leaving the page.
