title: LinkedIn API 401 Unauthorised when using Field Selectors
body: <p>I am attempting to get specific information from the user's profile via the LinkedIn API.</p>
  
  <p>The URL I am using for the GET call is the following:</p>
  
  <p><a href="http://api.linkedin.com/v1/people/~:(id,first-name,last-name,industry,headline,public-profile-url" rel="nofollow">http://api.linkedin.com/v1/people/~:(id,first-name,last-name,industry,headline,public-profile-url</a>)</p>
  
  <p>When attempting this I get a "401 Unauthorized" response from the server. However, when I do a GET to <a href="http://api.linkedin.com/v1/people/~" rel="nofollow">http://api.linkedin.com/v1/people/~</a> within the same function with the same auth keys, etc. it works just fine.</p>
  
  <p>The error presented in the response is as follows:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
  &lt;error&gt;
    &lt;status&gt;401&lt;/status&gt;
    &lt;timestamp&gt;1316082986700&lt;/timestamp&gt;
    &lt;request-id&gt;SVWTG5ARQM&lt;/request-id&gt;
    &lt;error-code&gt;0&lt;/error-code&gt;
    &lt;message&gt;[unauthorized].&lt;/message&gt;
  &lt;/error&gt;
  </code></pre>
  
  <p>Any ideas of why this might be happening? Anything would be greatly appreciated.</p>
