Python Google Checkout Notification API

I am attempting to work with Google Checkout on Google App Engine. Currently, I am writing everything in Python and have the checkout process working. I am having some difficulty getting the notifications of processed orders functioning. I've been sear开发者_Python百科ching for Python examples, but thus far have been unsuccessful. Programming directly off of the documentation provided by Google, I have not been able to get my notifications working either. Would anyone happen to have a framework/demo Google Checkout Notification example in Python?

The chippyshop source has a nice example of a python Google Checkout implementation that should get you moving in the right direction.

UPDATE: I actually ended up needing to do this myself so I extended the example linked above and turned it into a reusable RequestHandler for use on GAE.

You can find the source and examples on github which should serve as a good starting point for any others following this path.
