title: How to get Purchases.subscriptions: Details in Android
body: <p>I implemented in-app billing in my mobile app. It uses auto renewing subscription. I want to check the subscription expiry date through the app. I found this link to check the subscription details : <a href="https://developers.google.com/android-publisher/api-ref/purchases/subscriptions/get" rel="noreferrer">Purchases.subscriptions:get</a></p>
  
  <p>The documentation shows that some authorization needed. I have tried but I am not able to get the result. I got client secret.json file but it does not contain client secret Id. So please help me to get the subscription expiry date.</p>
