title: HP ALM 12.50 Rest API Sign-in returns forbidden using Postman
body: <p>I'm trying to sign in to HP ALM via its Rest API using Postman.</p>
  
  <p>Following the reference for 12.50 version (<a href="https://almsyngenta.saas.hpe.com/qcbin/Help/doc_library/api_refs/REST/webframe.htm#sign_in.htm" rel="nofollow noreferrer">https://almsyngenta.saas.hpe.com/qcbin/Help/doc_library/api_refs/REST/webframe.htm#sign_in.htm</a>), I'm sending a POST request to:</p>
  
  <pre><code>https://almalm1250saastrial.saas.hpe.com/qcbin/api/authentication/sign-in
  </code></pre>
  
  <p>Using the header:</p>
  
  <pre><code>Authorization: Basic &lt;Base64-encoded username:password&gt;
  </code></pre>
  
  <p>And the response i'm getting is:</p>
  
  <pre><code>HTTP Error 403 - Problem accessing /qcbin/api/authentication/sign-in. Reason: Forbidden
  </code></pre>
  
  <p>Does anyone know what's wrong with my request? I'm just following the reference I linked above.</p>
  
  <p>NOTE: The account used for the sign in process is a trial account and I can sign in with any problems from a browser.</p>
