namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Notifier\ChatterInterface;
use Symfony\Component\Notifier\Message\ChatMessage;
use Symfony\Component\Routing\Annotation\Route;

class CheckoutController extends AbstractController
{
    /**

     */
    public function thankyou(ChatterInterface $chatter)
    {
        $message = (new ChatMessage('You got a new invoice for 15 EUR.'))
            // if not set explicitly, the message is send to the
            // default transport (the first one configured)
            ->transport('slack');

        $chatter->send($message);

        // ...
    }
}
