title: How to set expiry time to shortened URLs
body: <p>I searched the web, which told me that the shortened URLs we get from different URL shortener websites are valid forever. But I want to make such a shortened URL with the help of those sites, which will be expired after some specific time, say 80 hours.</p>
  
  <p>Can someone please suggest how to achieve this?</p>
  
  <p>Thanks in Advance.</p>
