Introduction

This project is about using Perl to interact with the Google Checkout payment system. It provides a set of Perl modules which allows you to checkout, send commands, wait and process notifications.

Details

The code is written entirely in Perl which means no compiler is required for installation. The interface is in OO and the objective is to hide all the complexcity of the checkout flow from the users. There are ~43 modules in the whole code base but you will only need to use just a few. Please refer to the 'examples' directory for examples to post a cart, send command as well as process notifications. The structure of the code base tree is base on the following:

lib/
  Google/
    Checkout/
      Command/          <--- Modules related to command process
      General/          <--- General modules to interact with Checkout
      Notification/     <--- Modules related to process notification
      XML/              <--- XML reader / writer and constants
