E-commerce fraud script


The objective of this project is to enhance an existing open e-commerce platform to implement our customized fraud detection rules. The input to the new e-commerce app (NEA) will be an http post from an existing Order taking App (OTA) which will contain customer and product information as well as a cookie. The NEA process the order by saving the customer and product info into a MySQL database, execute a script that processes the fraud rules (described below), submit the transaction to a payment gateway when appropriate, and then pass the transaction back to the OTA with a result code.

Existing Order Taking App -> New E-Commerce Script with Fraud Rules -> Existing Order Taking App
