Which product should I choose?
The Quick Answer: API
When should I choose the Factory product?
Only our Factory supports the ability to add Amazon products in your store. However, through the use of other 3rd party plugins such as the WooCommerce Amazon Affiliate plugin, Amazon products can be added to your WooCommerce store if you are using the API product.
Additionally, you can display Amazon products using the API Product along with the Datafeedr Comparison Sets plugin.
