RESTful responds and cookies

Is there a way when responding with $this->respond() (RESTful API), to both send a json array and also send a cookie?
For example, if I use $this->response(), I can do

PHP Code:

$this->response->setJSON(['var' => 'value']);

$this->response->setCookie($cookie);

return $this->response; 


is it possible somehow or I can't use RESTful Resource Handling in such cases, I can't find anything about it
