title: Google Play refunds on in-app consumables fraud?
body: <p>One of my Android apps has an in-app item that is essentially a token which people can buy and use at a later time.</p>
  <p>I see that some people buy it and then refund it later. While implementing purchases I used the standard guide from Java section of the docs that Google provides on the topic, plus I do verify the purchases on my backend server.</p>
  <p>All that said, I'm still not sure that it can't potentially lead to some kind of fraud. Generally speaking, is it possible for the user to buy this &quot;token&quot; use it and then refund it in a matter of few minutes? I didn't look into it yet, but it doesn't seem that Google would bother to send a refund callback to my backend..</p>
  <p>Basically, how to handle these things correctly to prevent fraud?</p>
  <p>Edit: to be more clear, I do the acknowledgePurchase() and I get valid sales that don't get refunded, not after a while, not ever. I just wonder how is it so happens that from time to time I see a purchase made, then after some time (which differs in length) it does become &quot;refunded&quot; (but not all of them, only some).</p>
