error 403 for friend invitation

[Gavino]

I'm using the following php code to send a friend request 

    $apiCall = 'https://api.fitbit.com/1';
    
     $client = new Client($apiCall);
      
      $oauth = new OauthPlugin(array(
      'consumer_key'    => $conskey,
      'consumer_secret' => $conssec,
      'token'           => $apis->getToken(),
      'token_secret'    => $apis->getTokenSecret()
      ));

   
    $result=$client->addSubscriber($oauth); 
    
 // /1/user/-/friends/invitations.xml
    $send=$result->post('user/-/friends/invitations.xml',null , array('invitedUserId' => $friendid));
    
     $data = $send->send();

 but I get the error - 

Client error response
[status code] 403

@Gavino: Could you please post the actual HTTP request that you're making? If your HTTP client doesn't have verbose logging, you could use a tool like http://requestb.in/
