    <p>I want to build an app which generates a notification (like SMS -> mobile user will get a notification on his or her phone like while reciving a SMS) for a small range of users that are subscribing that notifications.</p> <p>I have build an App and such a Community Page (I'm not very familar with Facebook).</p> <p>Here is my code:</p> <pre class="lang-php prettyprint-override"><code>//PHP SDK require 'include/facebook.php'; //Instant Facebook-Object $facebook = new Facebook(array( 'appId' =&gt; '...', 'secret' =&gt; '...', 'cookie' =&gt; true, )); $user = $facebook-&gt;getUser(); if ($user) { try { // Proceed knowing you have a logged in user who's authenticated. $userData = $facebook-&gt;api('/me'); } catch (FacebookApiException $e) { error_log($e); $user = null; } } // If a user haven't been loged in, so the user have to authorize if (!$user) { $loginUrl = $facebook-&gt;getLoginUrl( array( 'scope' =&gt; 'publish_stream', 'redirect_uri' =&gt; 'http://my-hosting.url/' ) ); header('Location: '.$loginUrl); exit; } try { $publishStream = $facebook-&gt;api("/$testid/feed", 'post', array( 'message' =&gt; 'Hello World', 'link' =&gt; 'http://www.example.org/', 'name' =&gt; 'Test', 'description' =&gt; 'Wohoo some great text.', ) ); } catch (FacebookApiException $e) { var_dump($e); } </code></pre> <p>I'm playing with the <code>$testid</code> it contains e.g. <em>$user</em> or <em>community page ID</em>.</p> <p>In case of the user id I get the message on my wall but without any notification with is sad. If I change that to the <em>community page</em> I'll get an exception with this message:</p> <blockquote> <p>(#210) User not visible</p> </blockquote> <p>That seems that the community page is not allowed to to that. Well before I try to get that permission I would like to ask if this way is possible or if I'm just wasting my time.</p>
