Laravel postman request returns Unauthenticated

I'm new to laravel and sorry for the silly question I've posted a request via postman with two parameters,In my routes api.php file,

Route::post('/mail', 'TripsController@mail');

with header,

   Accept:application/json

And exclude the token verify in VerifyCSRKToken as,

protected $except = ['api/*',
      ];

and my url:

http://localhost/Movecabadmin/api/mail

It returns the message as {"message":"Unauthenticated."}

Question 1:Is I need to pass any authentication value with the request?If it is then How?

Question 2:How to get the passed parameters in my controller?
