Laravel route how to return response immediately (push and forget)

I am using Laravel 5.2. I have an api endpoint that receives calls from another server.

The other server doesn't need to wait to the response from my app. It is suppose to work in a way that the other server 'push' info to my app in a non-blocking way as much as possible.

I know that in regular php it can be achieved by sending:

header("HTTP/1.1 200 OK");
header('Connection: close');

At the beginning of the response.

Is there a way in the laravel controller to achieve the same thing?
