title: Get Token for Microsoft Graph API in Angular2
body: <p>Im using this <a href="https://github.com/benbaran/adal-angular4-example" rel="nofollow noreferrer">https://github.com/benbaran/adal-angular4-example</a> in my Angular app.</p>
  
  <p>When I use the token from this to access Microsoft Graph API I get the following response </p>
  
  <pre><code>{
  "error": {
      "code": "InvalidAuthenticationToken",
      "message": "Access token validation failure.",
      "innerError": {
          "request-id": "129e0d25-9553-4d9c-9075-5f82611e1847",
          "date": "2017-08-28T09:44:03"
      }
  }
  </code></pre>
  
  <p>What are the alternate ways to access Graph API in my Angular app. Libraries or SDK will also help. Thanks in advance.</p>
