title: Integrate Zoho rest API's
body: <p>I am trying to integrate <strong>Zoho rest API's</strong> to achieve below list of tasks.</p>
  <p><strong>Task List:</strong></p>
  <p>a) To get Project List
  b) To get Projects's Users list
  c) To get List of Task for the projects
  d) To Create new task</p>
  <p>I have successfully generated access token by following <a href="https://www.zoho.com/projects/help/rest-api/get-tickets-api.html#useAPI" rel="nofollow noreferrer">this</a>.</p>
  <p>AccessToken and refresh token:</p>
  <pre><code>{
      &quot;access_token&quot;: &quot;1000.53ea059005781cfc.ff08c750c671f7d1267e6de1e&quot;,
      &quot;refresh_token&quot;: &quot;1000.2a5ddc41fb6faccb42.b6c01194764f259049187f&quot;,
      &quot;api_domain&quot;: &quot;https://www.zohoapis.com&quot;,
      &quot;token_type&quot;: &quot;Bearer&quot;,
      &quot;expires_in&quot;: 3600
  }
  </code></pre>
  <p>When i try <a href="https://www.zoho.com/projects/help/rest-api/get-tickets-api.html" rel="nofollow noreferrer">get all portals operation</a>, it gives me error like &quot;Invalid OAuth access token.&quot; in the Postman.</p>
  <p><a href="https://i.stack.imgur.com/XQXP2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XQXP2.png" alt="Postman" /></a></p>
  <p>In <a href="https://www.zoho.com/projects/help/rest-api/portals-api.html" rel="nofollow noreferrer">Documentation</a> not much more details like what is request, what is URL etc given.</p>
  <p>How can I send a correct request to Project List or Projects's Users list?</p>
  <p>Any help would be highly appreciated.</p>
