title: In-app purchase 'SKProductsRequest' failing to produce a successful response
body: <p>We've been trying to test in-app purchases in a sandbox environment, but fail to receive any data back from an <code>SKProductsRequest</code>. The callback </p>
  
  <pre><code>- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
  </code></pre>
  
  <p>does get called but the response returns an empty array. Im testing this only for ipad, but both 3.2 and 4+ all seem to not get a response when I try this request.</p>
  
  <p>I have read throughly through all intunes connect documentation so to tie the app on the iTunes connect with its inapp purchase items, and also all apple documentation on the <code>SKProductsRequest</code> object and the <a href="http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/Introduction/Introduction.html" rel="nofollow">In App Purchase Programming Guide</a> for help. I have tried resetting the certificates and starting all from scratch and followed the 'build for distribution' helper in the ios provisioning portal. </p>
  
  <p>I have also built the app in all debug, release and distribution versions onto the device. I have watched and followed the <a href="https://developer.apple.com/videos/wwdc/2010/?id=310" rel="nofollow">WWDC2010 session 310 'App Publishing with iTunes Connect'</a>, but this is old as the enable inapp payments check button is no longer visible when creating app-ids in the provisioning portal site. </p>
  
  <p>I have also made sure that my code signing is correct and the program matches the right app-id to which the requested inapp purchases are signed-off with. (see attached, the bundleid matches the identifier in Xcode.</p>
  
  <p>I have made sure that the ipad has signed out of any iTunes accounts when running the test app, and added test users on the iTunes Connect page to test with. Our iTunes Connect banking information is fully completed.  </p>
  
  <p>I have also checked many forums and this process seems to be a big grey area for many, I have exhausted all thought on this, I just cant seem to get a response back for any product id.</p>
  
  <p>...can anyone help me?!! Thanks people!</p>
