Api Platform with Swift Mailer

I would know if API Platform is reliable to Swift Mailer. In fact, I woul use Swift Mailer to send a email when a new task has add. It works good when I use my controller, but not working with Postman or Swagger UI.

//mail sending
       $message = (new \Swift_Message('New task has done !'))
           ->setContentType('text/html')
           ->setFrom("fromAdresse@sample.fr")
           ->setTo('sample@email.com')
           ->setBody(
               $this->renderView('email/new.html.twig',
                    ['work' => $work]));
        $mailer->send($message);

I would use the same thing when users pass by the API UI, it's possible to handle the request ? Because controller and API hasn't the same route.

API : /api/works (POST) to add an element

Controller : work/new (POST) to add an element too

How I can use Swift Mailer on the API platform Request ? Or How I can handle the request with custom controller ?

Thx for advice and answers, I'm beginer with both.
