title: Box API get shared file results in 404
body: <p>Already looked at <a href="https://stackoverflow.com/questions/15004157/how-to-use-box-api-to-get-the-shared-item">How to use box-api to get the Shared item?</a> and Box Developers documentation <a href="https://developers.box.com/docs/#shared-items" rel="nofollow noreferrer">https://developers.box.com/docs/#shared-items</a>.  I have tried doing a request to <a href="https://api.box.com/2.0/shared_items" rel="nofollow noreferrer">https://api.box.com/2.0/shared_items</a> in .NET code, in Firefox Poster and using curl.  They all resulted in 404.  I have verified that my file's shared link is open to anyone with a link.  Here's my curl code (sanitized):</p>
  
  <pre><code>curl https://api.box.com/2.0/shared_items -H "Authorization: Bo
  xAuth api_key=xxxxxxxxxxxxxxxxxxxxx" -H "BoxApi: shared_link=https://
  app.box.com/s/yyyyyyyyyyyyyyyyyyyyyyyyyyyy"
  
  {"type":"error","status":404,"code":"not_found","help_url":"http:\/\/developers.
  box.com\/docs\/#errors","message":"Not Found","request_id":"196207167555469c3017
  14b"}
  </code></pre>
  
  <p>What might be the problem?  I tried a wrong api_key and got back 401 so I know the whole setup is correct.</p>
