When creating an affiliate link you will be able to change the link type to “Amazon Product”, which will allow you to search through Amazon products directly for your affiliate links.
Setting up your Amazon PA-API Keys
If you have access to the Amazon Product Advertising API (which you get for free once you generate a few sales) you can add your API keys on the Affiliate Links > Settings > Amazon page to enable this feature:
Make sure to select the correct store country and set your Amazon Store ID (as found in the top right of the Amazon Associates Central). On the Product Advertising API page you can create your credentials (if eligible) and add the Access and Secret Key that Amazon provides to our settings.
Take note that if you’ve only just created the credentials, they might not work immediately. If the integration doesn’t work yet, give it about 24-48 hours.
