title: Cloud Endpoints: Control who can execute API through API Explorer
body: <p>Everyone who successfully authenticates through Google account would be able to execute the API through the API Explorer.</p>
  
  <p>I would like to limit the ability to execute the API through API Explorer only to some users. But at the same time have the API accessible for all users of my Android and iOS apps. </p>
  
  <p>Security in the case of at least Android App is facilitated through the Android Client Id and SHA fingerprint. So, the scope here is to NOT include the App access security. </p>
