Facebook passes in your data as part of the signed_Request data. Here is how you would retrieve it using PHP:

 $app_id,
        'secret' => $app_secret,
        'cookie' => true
));


// THE MAGIC SAUCE
$signed_request = $facebook->getSignedRequest();

$page_id = $signed_request["page"]["id"];
$like_status = $signed_request["page"]["liked"];
// HERE IS A STRING OF YOUR APP DATA.
$app_data = $signed_request["app_data"];

echo '$app_data = '.$app_data;
?>

This example requires the Facebook PHP api and will write your app_data into the browser window where you can marvel in all its glory.
