title: Accessing public Instagram content via Instagram API without expiring accesstoken
body: <p>i want to show public contents from instagram related to a specific hashtag (everything works fine with that) but i can't to renew the <code>access_token</code> everytime it expires.</p>
  
  <blockquote>
    <p>("do not assume your access_token is valid forever." -
    <a href="https://www.instagram.com/developer/authentication/" rel="noreferrer">https://www.instagram.com/developer/authentication/</a>)</p>
  </blockquote>
  
  <p>To renew it manually is not an option i have to make sure there is a valid <code>access_token</code> at ANY time without re-authenticating. </p>
  
  <p>Any ideas or questions? :)</p>
