Am new to Facebook sdk and i want to use it in my project (blackberry app) has the developer i tried writing to my timeline with the code blow through a web service and i was able to write to my timeline, my question is this must i create an action and object that must be submitted for approval before other users can use my app to write to their timeline? because permission are not granted when users try to write to their timeline.

$ret_obj = $facebook->api('/me/feed', 'POST',array('link' => 'www.****.com','message' => $user_profile["name"].' just downloaded W1'));
    echo '<pre>Post ID: ' . $ret_obj['id'] . '</pre>';
