Google analytics can be used for tracking e-commerce transactions as well, more info here: [login to view URL] What I will like to do is use this open source project to track ecommerce transactions via calling the google analytics URL on server side rather than using javascript code on the thank you page: [login to view URL] What I am looking for: 1.) a php script that uses the above library and can track an ecommerce transaction 2.) Whatever values are required for tracking an ecommerce transaction through google analytics can be passed to the php script you develop as "POST" parameters. The list of parameters are: "OrderID, affiliation, total, sku, product name, siteID(this will be mapped to the google analytics account like UA-XXXX-X) SiteID passed will be numeric like 34562, and the php script needs to have a mapping for 34562 to google account like UA-XXXX-X 3.) Also, I want to use "utmtst" parameter within google analytics that can be passed to the php script you develop as part of the POST 4.) Details instructions on how to set this php script on my server, and how to test the script you develop
