I tried searching on the net for an example but all I come across are confusing info, scripts that no longer work, or really complex stand alone scripts that work alone. I simply want a php example that works with my current site. I can do all of the php editing, but do not know the Google Checkout API end for it to send data back for approved purchases. Thanks.

I wrote a Paypal and 2Checkout class. I'll try if I can work on Google Checkout.

If you have experience with PHP, it shouldn't be hard to implement their API - they must have some sort of documentation and implementation samples.

Peace,

Thanks, any updates?

They do, signup with google if you dont have an account, its under google checkout, info and forums on api

Are you talking about the call back url setting or IPN notification setting in Google API ??
