Hi

I need to integrate google checkout on my website. I have successfully implemented the order placing and others stuff and using the sandbox I have tested that users can successfully add items to cart and and pay thereafter. I am using my own customized shopping cart written in php mysql.

The last thing I need to do is pass the new order id to google checkout and receive notifications with the new order id as well as other data google sends. I know I have to setup a path to the handler script in my accounts. I did it in my sandbox account as well. But can't find a simple pice of code to get it done.

Even if I use sample code from google, just cant figure out the format of the returned data in new order notification and also how to send custom data to the cart, which would come back with new order notifications?

I am just lost on this. Please help!
