title: Get the transaction history from Android Pay via API?
body: <p>Our application (an expenses manager) would like to extract the <strong>transaction history</strong> from <em>Android Pay</em> in order to make it easier for the user to enter their purchase history. Is this possible - either through an <strong>Android app</strong> on the same phone where the purchases were made or through an <strong>external API</strong>?</p>
  
  <p>I've found plenty of information on how to integrate <em>Android Pay</em> payments from within the app, but nothing on how to access the previous transactions.</p>
