title: Chrome Webstore Extension In App Purchase INTERNAL_SERVER_ERROR
body: <p>Partial success with the Chrome InApp purchase flow within a Chrome extension. I have included the buy.js file and implemented the flow as listed on the Chrome walkthrough here:</p>
  
  <p><a href="https://developer.chrome.com/webstore/payments-iap" rel="nofollow">https://developer.chrome.com/webstore/payments-iap</a></p>
  
  <p>Using my live extension, I have run through the flow and it works just fine. My credit card is charged and the callback returns successful, I deliver the item. When I check the google.payments.inapp.getPurchases call I can see the item listed as ACTIVE.</p>
  
  <p>However, when I install the production/live extension on any other test computer (a friend's), and try to launch the google.payments.inapp.buy  flow, I get one of two results:</p>
  
  <p>1) A grayed out graphic with the text "In-App Payments is currently unavailable. The transaction could not be completed. Please try again later"</p>
  
  <p>2) A blank window opens, then closes immediately.</p>
  
  <p>The "failure" callback comes back with the error "INTERNAL_SERVER_ERROR." </p>
  
  <p>Again, the purchase flow works fine on my own Google account, but cannot be completed successfully on any other account. My own internal tracking is showing that 0% of users are completing purchases successfully and this leads me to believe the error is widespread. I know users are trying to make purchases due to internal tracking I have set up, but the only revenue in my Chrome dashboard is from my own test purchases. Something smells funny.</p>
  
  <p>Do any Chrome Webstore Devs have experience with successful in-app payments purchases on live extensions? Help!</p>
