title: Postman - Not able to send request with client_credentials grant_type
body: <p><a href="https://i.stack.imgur.com/PgVGk.png" rel="noreferrer"><img src="https://i.stack.imgur.com/PgVGk.png" alt="Image"></a>I am trying to get an accessToken from Microsoft Graph API using Postman tool. I am trying it in Authorization tab with Type=oauth2.0, so that I can use this accessToken for subsequent Get,Post requests.</p>
  
  <p>Everything works fine, if the grant_type is "Authorization Code". But when the grant_type is <strong>client_credentials</strong>, postman throws the below error </p>
  
  <blockquote>
    <p>error getting access token from client_credentials flow. Could not
    send request</p>
  </blockquote>
  
  <p>I have looked at the Network tab in DeveloperTools, it does not submit  Client_Id, Client_Secret for client_credentials flow. </p>
  
  <p><strong>Question:</strong>  How can I get Postman work for <strong>client_credentials</strong> grant_type scenario?</p>
  
  <p>Am I missing any step here? Please guide me..</p>
  
  <p>Thanks</p>
