unauthorized(401) error in jquery laravel

i developed the API in Laravel for authentication and authorization. while user user authentication at api side (through postman) is working fine, as i login from the API from front side it giving unauthorized error

below is my code where i am getting it wrong. or am I using wrong approach at frontend side?

   $(function () {
            $.ajaxSetup({
                    headers: {
                            'X-XSRF-TOKEN': $('meta[name="_token"]').attr('content')
                    }
            });
    });
    
  $('#ajaxcall').on('click', function(e) {
      
       
          e.preventDefault();
                var email = $('#email').val();
                var password = $('#password').val();
                var token = $('input[name="_token"').val();
                $.ajax({
                    url: '{{url("api/login")}}',
                    type: "post",
                    data: {
                        '_token': token,
                        'email': email,
                        'password': password
                    },
                    success: function(res) {
                        console.log(res)
                        if (res.error) {
                            $('#loginerror').text(res.error)
                        }
                        if (res.success) {
                            window.location.href = '/home';
                        }
                    }
                })
          
   });
