API – Application Programming Interface
Amazon’s MWS uses an API to allow communication between its sellers and their product data. It’s the software that makes Amazon data accessible to you about your own Amazon products via the Internet.
For example, when you want to create a product listing and add keywords into Amazon’s server that Amazon then uses in its SEO, you are working through Amazon’s MWS API. When you use Helium 10’s tools, you are also using an API, but it includes information made available by Amazon on more than one seller’s products.
