Cancel and refund ALL google play subscriptions
<p>We have an app in the Google Play Store that we will no longer support in the future. </p>

<p>Users were able to buy subscriptions for the app's content. </p>

<p>We want to cancel all running subscriptions and refund the users. </p>

<p>The Google Play Developer Api offers the <a href="https://developers.google.com/android-publisher/api-ref/purchases/subscriptions/revoke" rel="noreferrer">revoke</a> method that expects the details (subscription id, token) for a single subscription and will cancel &amp; refund that subscription. </p>

<p>We would have to do that for a couple of thousands of users (probably via a script). </p>

<p>Is there a better way to revoke all subscriptions? 
Has someone probably faced a similar scenario? </p>
