Kik Node API

Getting Started

Use this library to communicate with the Kik API to develop a bot for Kik Messenger. Got to dev.kik.com to learn more and start building a bot.

Install with npm install @kikinteractive/kik

How To

Creating a basic Kik bot is simple:

Import @kikinteractive/kik
Create a bot with the username and API key you got from https://dev.kik.com/
Configure your bot as described in the documentation
Add the bot as middleware to your server with bot.incoming()
Start your web server

You can use any node-style web server to host your Kik bot. Add handlers to your bot by calling bot.onTextMessage(...) and get notified whenever a user messages you. Take action on the messages as they come in and call message.reply(...) to respond to the message within the chat the message was sent from.

Check out the full API documentation for more advanced uses.

Your first echo bot

'use strict';

let util = require('util');
let http = require('http');
let Bot  = require('@kikinteractive/kik');

// Configure the bot API endpoint, details for your bot
let bot = new Bot({
    username: 'echo.bot',
    apiKey: '7b939d69-e840-4d22-aab8-4188c2198f8a',
    baseUrl: 'https://kik-echobot.ngrok.io/'
});

bot.updateBotConfiguration();

bot.onTextMessage((message) => {
    message.reply(message.body);
});

// Set up your server and start listening
let server = http
    .createServer(bot.incoming())
    .listen(process.env.PORT || 8080);

Sending a message to a specific user

You can send a targeted message to a user once they have subscribed to your bot. If you want to send someone a message, just call bot.send(...) with their username. You don't need to specify a chat ID here since you are sending it directly to the user, not within a specific chat.

// To one user (a.username)
bot.send(Bot.Message.text('Hey, nice to meet you!'), 'a.username');

// You can use a shorthand for text messages to keep things a bit cleaner
bot.send('Getting started is super easy!', 'a.username');

Sending a picture message

If you want to send a photo to a user you can send a picture message. The API will download the image you supply and pass it along. You have to set the attribution name and icon for the message so the knows where the content came from even if it's forwarded later.

bot.send(Bot.Message.picture('http://i.imgur.com/oalyVlU.jpg')
    .setAttributionName('Imgur')
    .setAttributionIcon('http://s.imgur.com/images/favicon-96x96.png'),
    'a.username');

Greeting a user by name

Whenever a user subscribes to your bot, your bot will receive a start-chatting message. This message gives you the chance to say hello to the user and let them know what your bot is about.

You might want to greet your new user by name. You can use the bot.getUserProfile(...) method to request information about users who have subscribed to your bot.

bot.onStartChattingMessage((message) => {
    bot.getUserProfile(message.from)
        .then((user) => {
            message.reply(`Hey ${user.firstName}!`);
        });
});

Adding multiple handlers

Separating different states into multiple message handlers can keep your bot logic under control. If you call next from within your handler, you allow the next handler in the chain to run, otherwise, handling of the incoming message will end with the current handler.

bot.onTextMessage((message, next) => {
    const userState = getUserState(message.from);

    if (!userState.inIntroState) {
        // Send the user the intro state
        // ...

        return;
    }

    // Allow the next handler take over
    next();
});

bot.onTextMessage((message) => {
    searchFor(message.body)
        .then((result) => {
            message.reply(result);
        });
});

Setting a static keyboard

You can specify a static keyboard for your bot when a user starts mentioning it in a conversation:

let bot = new Bot({
    username: 'echo.bot',
    apiKey: '7b939d69-e840-4d22-aab8-4188c2198f8a',
    baseUrl: 'https://kik-echobot.ngrok.io/',
    staticKeyboard: new Bot.ResponseKeyboard(['Option 1', 'Option 2'])
});

API Documentation

Bot

Parses user messages sent from Kik's server. Use the .incoming() method to return the middleware in a form of function (req, res, next) {}. The middleware will automatically decode the request, and call the appropriate on functions based on the content type. Additional middleware can be used by calling the .use(handler) method.
