A2S Simple Store with Request Signing in PHP

This is a simple PHP 5 application demonstrating the basics of how to interact with Amazon Associates Web Service (A2S, formerly known as ECS).

This sample is based on the Amazon A2S Simple Store PHP script, which stopped working when Amazon started requiring cryptographic signatures on Amazon API requests.

About This Sample

• This application is meant to demonstrate the ItemSearch, ItemLookup, CartCreate, CartAdd, and CartModify operations. It is not intended to be be comprehensive example of how to build an e-commerce store. For example, on an ItemSearch by Keywords, this sample only returns items that are for sale by Amazon (as opposed to other Merchants).
• This sample was tested on PHP 5.1.4.

What's New

• 2007-04-06: This sample now presents a "See Cart Contents" link when items are in the shoppers cart. Previously, a shopper could only see cart contents upon adding an item to the cart.
• 2016-04-06: (Franklin Veaux) This sample has been updated to include code signatures, hardened against security exploits, and other bugs have been fixed. Additional debugging is available in the code; see code comments for more.
