DESCRIPTION

    LINE::Bot::API is a client library to easily use the LINE BOT API. You
    can create a bot which will run on the LINE App by registering your bot
    account. Your BOT API Trial account can be created from LINE BUSINESS
    CENTER <https://business.line.me/>.

    You can find the Channel ID, Channel Secret and MID on the Basic
    information page at LINE developers <https://developers.line.me/>.

    Please use this POD and LINE developers site's online documentation to
    enjoy your bot development work!

METHODS

 new()

    Create a new LINE::Bot::API instance.

        my $bot = LINE::Bot::API->new(
            channel_id     => 'YOUR LINE BOT Channel ID',
            channel_secret => 'YOUR LINE BOT Channel Secret',
            channel_mid    => 'YOUR LINE BOT MID',
        );

 Sending messages

    The to_mid parameter for the Sending message API.

        $bot->send_text(
            to_mid = $mid,
        );

    When you use a SCALAR value in the to_mid, this method sends message to
    one person. Although if you use ARRAY ref in the to_mid, this sends
    message to all mids in the ARRAY.

        $bot->send_text(
            to_mid = [ $mid1, $mid2, $mid3, ... ],
        );

    See also a online documentation.

    ## Receiving messages/operation

    The following utility methods allow you to easily process messages sent
    from the BOT API platform via a Callback URL.

  validate_signature()

        my $req = Plack::Request->new( ... );
        unless ($bot->validate_signature($req->content, $req->header('X-LINE-ChannelSignature'))) {
            die 'failed to signature validation';
        }

  create_receives_from_json()

        my $req = Plack::Request->new( ... );
        my $receives = $bot->create_receives_from_json($req->content);

    See also LINE::Bot::Receive.

 Getting message content

    You can retreive the binary contents (image files and video files)
    which was sent from the user to your bot's account.

        my $receives = $bot->create_receives_from_json($req->content);
        for my $receive (@{ $receives }) {
            next unless $receive->is_message && ($receive->is_image || $receive->is_video);
            if ($receive->is_image) {
                my($temp) = $bot->get_message_content($receive->content_id);
                my $original_image = $temp->filename;
            } elsif ($receive->is_video) {
                my($temp) = $bot->get_message_content($receive->content_id);
                my $original_video = $temp->filename;
            }
            my($temp) = $bot->get_preview_message_content($receive->content_id);
            my $preview_image = $temp->filename;
        }

    See also a online documentation.
    https://developers.line.me/bot-api/api-reference#getting_message_content

  get_message_content()

    Get the original file which was sent by user.

  get_preview_message_content()

    Get the preview image file which was sent by user.

 Getting user profile information

    You can retrieve the user profile information by specifying the mid.

    See also a online document.
    https://developers.line.me/bot-api/api-reference#getting_user_profile_information

        my $res = $bot->get_user_profile(@mids);
        say $res->{contacts}[0]{displayName};
        say $res->{contacts}[0]{mid};
        say $res->{contacts}[0]{pictureUrl};
        say $res->{contacts}[0]{statusMessage};
