title: Get all posts base on Hashtag search Instagram API
body: <p>I want a API, to get all the posts, search by hashtag in Instagram.</p>
  <p>As per my research, I can use Graph API to do the same. But I did not get a proper tutorial from scratch.</p>
  <p>Can someone suggest me proper guidelines for it.</p>
  <p>Currently I am using following api.</p>
  <p><strong><a href="https://api.instagram.com/v1/tags" rel="nofollow noreferrer">https://api.instagram.com/v1/tags</a></strong></p>
  <p>And I am getting following error, even I am passing valid access_token.</p>
  <pre><code>{
  &quot;meta&quot;: {
      &quot;code&quot;: 400,
      &quot;error_type&quot;: &quot;OAuthAccessTokenException&quot;,
      &quot;error_message&quot;: &quot;The access_token provided is invalid.&quot;
  }
  }
  </code></pre>
