I have a merchant account on Google checkout. I can view all the orders buyers put when I log on to https://checkout.google.com/sell/orders. From there, I can search for a specific order number and view details about it.
I want to do the same programmatically, but after looking through the checkout API I can not find anything related to this issue. Basically my input will be an order number and the output I want will be details regarding that ordre, or at least a boolean indicating whether that order exists or not.
