=head1 SYNOPSIS

Castle detects and mitigates account takeover in web and mobile apps. This is a third party API client built for the Castle.io API.


=head1 CONFIGURATION

    use WebService::CastleIO;

    my $castle = WebService::CastleIO->new(
        api_secret => 'sRq3Zmzpxwu6eDXiYCFB3xyfi4ZnVjnn',
        cookie_id  => 'abcd',
        ip_address => '24.61.128.172',
        headers    => JSON->new->allow_nonref->utf8->encode({'User-Agent' => 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0'}),
        source     => 'backend',
        debug      => 1
     );


=head1 SUBROUTINES/METHODS


=head2 track

Track lets you record security-related actions your users perform. Events are processed
asynchronously to return as quickly as possible.

    my $event_result = $castle->track(
        data => {user_id => 'dummy', name => '$login.succeeded', properties => {threat => 'Large', whatever => 'made up'}}
    );

=cut

sub track {
  my ($self, %params) = validated_hash(
    \@_,
    data    => {isa => 'Maybe[HashRef]'},
  );

  say '[track] Create new event' if $self->debug;

  $self->_call(endpoint => 'track', args => \%params, method => 'POST');
}



=head2 authenticate

Authenticate is processed synchronous and returns returns an action of the types approve, challenge or deny.

    my $auth_result = $castle->authenticate(
        data => {user_id => 'dummywriter', name => '$login.succeeded'},
    );


=cut

sub authenticate {
  my ($self, %params) = validated_hash(
    \@_,
    data => {isa => 'Maybe[HashRef]'},
  );

  say '[authenticate] Authenticate user' if $self->debug;

  $self->_call(endpoint => 'authenticate', args => \%params, method => 'POST');
}




=head2 identify

User updates are processed asynchronously to return as quickly as possible.

    my $identify_result = $castle->identify(
        data => {user_id => 'dummywriter', traits => {'foo' => 'bar'}},
    );

=cut

sub identify {
  my ($self, %params) = validated_hash(
    \@_,
    data => {isa => 'Maybe[HashRef]'},
  );

  say '[identify] Identify user' if $self->debug;

  $self->_call(endpoint => 'identify', args => \%params, method => 'POST');
}



=head2 review

Reviews lets you fetch the context for a user to review anomalous account activity.

    my $reviews_result = $castle->review(review_id => 12356789);

=cut

sub review {
  my ($self, %params) = validated_hash(
    \@_,
    review_id => {isa => 'Int'}
  );

  say '[review] Review user activity' if $self->debug;

  $self->_call(endpoint => "reviews/$params{review_id}", args => \%params, method => 'GET');
}



=head2 _call

Private method that makes call to API web service.

=cut

sub _call {
  my ($self, %params) = validated_hash(
    \@_,
    endpoint => {isa => 'Str'},
    args     => {isa => 'Maybe[HashRef]'},
    method   => {isa => enum([qw(POST GET)])}
  );

  my $headers = {
      'X-Castle-Ip'                => $self->ip_address,
      'X-Castle-Source'            => $self->source,
      'X-Castle-Cookie-Id'         => $self->cookie_id,
      'X-Castle-Headers'           => $self->headers,
      'X-Castle-Client-User-Agent' => $self->_client_user_agent,
      'Content-Type'               => 'application/json',
      'User-Agent'                 => 'Castle API Client ' . $VERSION
  };

  my $url = $self->api_url . '/' . $params{endpoint} . '.' . $self->format;

  my $client = REST::Client->new();
  $client->addHeader("Authorization", "Basic " . encode_base64(':' . $self->api_secret, ''));

  for ($params{method}) {
    when ('GET')  {
      say "[_call]: Making call GET $url" if $self->debug;
      my $url_args  = defined $params{args}{data} ? '?' . join('&', map {"$_=$params{args}{data}{$_}"} keys %{$params{args}{data}}) : '';
      $url .= $url_args;
      $client->GET($url);
    }
    when ('POST') {
      my $json_args = JSON->new->allow_nonref->utf8->encode($params{args}{data});
      say "[_call]: Making call POST $url" if $self->debug;
      $client->POST($url, $json_args, $headers)
    }
  }

  $client->responseCode();
}



=head2 _client_user_agent

Private method to return user agent.

=cut

sub _client_user_agent {
    JSON->new->allow_nonref->utf8->encode({
      bindings_version => $VERSION,
      lang             => 'perl',
      publisher        => 'castle',
      uname            => `uname -a`
    });
}



=head2 _json_to_object

Private method that converts JSON result to object

=cut

sub _json_to_object {
  my $self = shift;
