    text
    copied!<p>NOTE: When the user accepts my permissions to use my app. I ask them to accept <code>manage_notifications</code></p> <p>I am so confused. I research this on the web and it seems I get a mix of deprecated and wrong information and I am trying to send a notification to the user using my facebook canvas app using facebook graph. the following is how I do it and its not working.</p> <pre><code>public function getAccessToken() { $app_id = $this-&gt;settings['app_id']; $app_secrete = $this-&gt;settings['app_secrete']; $url = "https://graph.facebook.com/oauth/access_token?". "client_id={$app_id}". "&amp;client_secret={$app_secrete}". "&amp;grant_type=client_credentials"; $c = curl_init($url); // necessary so CURL doesn't dump the results on your page curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($c); $result = explode("=", $result); curl_close ($c); return $result[1]; } </code></pre> <p>The result passes something like this <code>access_token=523216317ewwer235|K4A1XugBpajwrweu1K2k12jzckdU</code> . so that is why i explode the <code>=</code> sign within the code. I call this function every time the user enters my app. I take the access code and pass it as <code>$token</code> in the following code.</p> <pre><code>public function alertUser($userid,$token,$message="You have a notification") { $inviteMessage = $message; $inviteMessage = urlencode($inviteMessage); $url = "https://graph.facebook.com/{$userid}/notifications?access_token={$token}&amp;". "template={$inviteMessage}&amp;ref=notify"; $c = curl_init($url); // necessary so CURL doesn't dump the results on your page curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($c); curl_close ($c); $r = json_decode($result); } </code></pre> <p>and I get the following response</p> <pre><code>object(stdClass) { error =&gt; object(stdClass) { message =&gt; 'A user access token is required to request this resource.' type =&gt; 'OAuthException' code =&gt; (int) 102 } } </code></pre>
