title: How to consume the subscription type in app product purchase
body: <p>I have implemented the subscription type in-app products in my app like 1 month or 2 months package, once a user subscribe to the product I let the server know and deal with him/her accordingly and it is working very fine. </p>
  
  <p>According to Google at completion of subscription period:</p>
  
  <blockquote>
    <p>Google auto-cut the credit and renew the package.</p>
  </blockquote>
  
  <p><strong>My problem:</strong> How do I get to know the user who have paid for next the month or not?</p>
