Facebook OAuth: custom callback_uri parameters

I\'d like to have a dynamic redirect URL for my Facebook OAuth2 integration. For example, if my redirect URL is this in my Facebook app:

http://www.mysite.com/oau

You should set your custom state parameter using the login helper as such:

use Facebook\Facebook;
use Illuminate\Support\Str;

$fb = new Facebook([
    'app_id' => env('FB_APP_ID'),
    'app_secret' => env('FB_APP_SECRET'),
    'default_graph_version' => env('FB_APP_VER'),
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = [
    'public_profile',
    'user_link',
    'email',
    'read_insights',
    'pages_show_list',
    'instagram_basic',
    'instagram_manage_insights',
    'manage_pages'
];

$random = Str::random(20);

$OAuth2Client = $fb->getOAuth2Client();

$redirectLoginHelper = $fb->getRedirectLoginHelper();

$persistentDataHandler = $redirectLoginHelper->getPersistentDataHandler();

$persistentDataHandler->set('state', $random);

$loginUrl = $OAuth2Client->getAuthorizationUrl(
        url('/') . '/auth/facebook',
        $random,
        $permissions
    );
