title: Facebook JSDK posting on user's friends wall
body: <p>I'm trying to post on the user's friends wall trough javascript SDK. The basic function is that the user creates a team and invites his/her friends to join it.</p>
  
  <p>Let's say I got an appropriate access token with all the needed permissions.</p>
  
  <p>Now after the user selected a friend (for the sake of simplicity now this is one user with id 12345678), I call this:</p>
  
  <pre><code>FB.api('/12345678/feed', 'post', {
          name: 'Test post',
          caption: 'Test caption',
          link: 'https://my.example.com/invite/',
          description: 'Join my awesome team',
          message: 'Join my awesome team'
      },function(response) {console.log(response);});
  </code></pre>
  
  <p>My problem is that even though I get back a post ID successfully, nothing is shown on the selected user's wall. If I post to the user's feed with the SAME access token trough the Graph API explorer manually, it works.</p>
  
  <p>What do I do wrong? How come I can't send this trough my app, yet I can use the Graph API to send a message? Both are unapproved apps by the 'friend' I try to send a message to? </p>
  
  <p>Thanks</p>
