title: Find Instagram media url by ID
body: <p>Thanks to a HTTP call not very official, I find media ID, image URL, and user name of Instagram posts.</p>
  <p>But I need the URL of each post on Instagram, and I don't know how to find it.</p>
  <p>Is there an URL like <code>instagram.com/something/{mediaID}</code> which redirect to <code>instagram.com/p/{mediaSlug}</code>, or another method to find slug by media ID (without using the official API of course!) ?</p>
  <p>For example, I've got :</p>
  <blockquote>
  <p>Unique number : 1238578393243739028_1408429375</p>
  <p>Media ID : 1238578393243739028</p>
  <p>User ID : 1408429375</p>
  </blockquote>
  <p>And I would :</p>
  <blockquote>
  <p><a href="https://www.instagram.com/p/BEwUHyDxGOU/" rel="noreferrer">https://www.instagram.com/p/BEwUHyDxGOU/</a></p>
  </blockquote>
  <p>Thanks for your help !</p>
