I have a CRELoaded website (CRE Loaded PCI CE v6.4.1a at revision:2486, MySQL 5.0.77) Currently I am using the Amazon Checkout for OS Commerce Cart Plug-in Version 2.3.1. The checkout is just another option on the checkout page. However, the integration is not complete. I am currently getting duplicate orders, IOPN creates a second order) and I am not able to manage my Amazon paid orders from my CRE loaded Admin panel. When the order ships the status on the Amazon payments is not modified and tracking number is not posted on the Amazon side. I need to have the integration of the Amazon Checkout completed.
If you are not familiar of how Amazon checkout works and you haven't done this please DO NOT BID on this project. Only folks who have done this before should bid. If you have questions please ask.
