laravel automatically generates csrf "token" each active user session managed application. token used verify authenticated user 1 making requests application.

anytime define html form in application, should include hidden csrf token field in form csrf protection middleware can validate request. may use csrf_field helper generate token field:

<form method="post" action="/profile">     {{ csrf_field() }}     ... </form> 

in addition checking csrf token post parameter, verifycsrftoken middleware check x-csrf-token request header. could, example, store token in html meta tag:

<meta name="csrf-token" content="{{ csrf_token() }}"> 

then, once have created meta tag, can instruct library jquery automatically add token request headers. provides simple, convenient csrf protection ajax based applications:

$.ajaxsetup({     headers: {         'x-csrf-token': $('meta[name="csrf-token"]').attr('content')     } });
