For anyone who would find this helpful, I was losing sleep and wrecking my brain for days trying to get this to work;

FB.api('/me/permissions', 'DELETE', function(response) {
    if (response == true) {
        window.top.location = 'logout-facebook.php';
    } else {
        alert('Error revoking app');
    }
});

I finally got this to work when I observed that the "response" being returned was not a boolean but a JSON object.

The JSON object being returned was either;

{
    success: "true"
}

OR

{
    success: "false"
}

Following that, the correct code was;

FB.api('/me/permissions', 'DELETE', function(response) {
    if (response.success == true) {
        window.top.location = 'logout-facebook.php';
    } else {
        alert('Error revoking app');
    }
});   

Hope this helps someone!
