How to write on route to receive request from external laravel project

$client = new Client();
$response = 
$client->GET('http://ift.tt/2k8SDG6',
[
 'json' => ['foo' => 'bar']
]);

This is how i'm sending a request to external LARAVEL api. I just want to know what do i need to write in laravel api router to get something return when i send this request. Currently i have the following code on laravel api router

Route::GET('module/url', 'Nameof Controller@NameOfMethhod');

And in controller looks like:

public function GetApplicationModuleList()
{
  echo 'something';
  //i want to print the parameter value which i just sent by above mention request.
}
