Amazon API to pull item specific data from Amazon.com(repost)(repost)

Amazon recently implemented some changes and thus you need to be familiar with the recent changes using Amazon APIs. For this project you should be familiar with [login to view URL] and the APIs that are available to pull data from Amazon. You need to have your Amazon credentials when you are creating the software. Once the work is done and I have fully tested the software for accuracy and completion, you will need to show me how I can put in my API credentials from a text file on my PC. I will not share my API credentials with you. I am looking for an automated program that will accomplish the following for me. Take an input text file and look up certain data on [login to view URL] and put the looked up data into an output text file. The input file will contain four columns. However, the only column you really need to look up the data is column c (the UPC code). The input source file can be any number of records so the software must work on any number of records. The data in the records will change each time I run the software. Please refer to the example input file. The output file will contain all the data as provided in the input file plus the following information (please refer to the included output file). You must review the complete attached word file and input and output files prior to bidding.
