title: Can I obtain Google Checkout Order Id for a purchased Android app from the app itself?
body: <p>We would like to allow our users to activate a service on one of our servers with each app purchased from the Android Market, verifying that the user has really purchased the app.</p>
  
  <p>For this purpose we are evaluating to use Google Checkout's Notification History API, which allows us to query from our server the status of a Checkout Order ID.</p>
  
  <p>Now the problem is that we don't know how to obtain the Checkout Order Id from the app itself.</p>
  
  <p>With the new in-app purchases API we can get Checkout Order Id for each one of the in-app purchases, but not for the app purchase.</p>
