History of APIs - Amazon E-Commerce

Amazon.com Web Services (AWS) allowed third party sites to search and display products from Amazon.com. Product data was made accessible using XML and SOAP.

From day one the API was integrated with the Amazon.com Affiliate Program, allowing developers to monetize their sites through purchases made at Amazon.com via links from their web sites.

Internet visionary Tim O'Reilly was quoted in original Amazon Web Services press release saying, "This is a significant leap forward in the next-generation programmable internet."

APIs and Amazon both have roots in e-commerce, but APIs were quickly applied to other areas resulting in the social media, cloud computing and now the mobile technology movements.
