The Google Checkout orders page allows you to download the orders data as CSV. There is a checkbox that allows you to specify that the CSV should include extra data (buyer's name and address, product details).
The Google Checkout Order Report API provides a way to get CSV order data programmatically. However, it doesn't seem to be possible to get the data in the extended format. Am I missing something? Is there some way to specify that you want the full data?
The default data is pretty uninformative.
