    Connect Botkit or BotBuilder to Google Hangouts.

    This package contains an adapter that communicates directly with the Google Hangouts API, and translates messages to and from a standard format used by your bot. This package can be used alongside your favorite bot development framework to build bots that work with Google Hangouts.

    Install Package

    Add this package to your project using npm:

    npm install --save botbuilder-adapter-hangouts

    Import the adapter class into your code:

    const { HangoutsAdapter } = require('botbuilder-adapter-hangouts');

    Get Started

    If you are starting a brand new project, follow these instructions to create a customized application template.

    Use HangoutsAdapter in your App

    HangoutsAdapter provides a translation layer for Botkit and BotBuilder so that bot developers can connect to Google Hangouts and have access to the Google Hangouts's API.

    Botkit Basics

    When used in concert with Botkit, developers need only pass the configured adapter to the Botkit constructor, as seen below. Botkit will automatically create and configure the webhook endpoints and other options necessary for communicating with Google.

    Developers can then bind to Botkit's event emitting system using controller.on and controller.hears to filter and handle incoming events from the messaging platform. Learn more about Botkit's core feature →.

    A full description of the HangoutsAdapter options and example code can be found in the class reference docs.

    const adapter = new HangoutsAdapter({
        token: process.env.GOOGLE_TOKEN,
        google_auth_params: {
            credentials: process.env.GOOGLE_CREDS
    const controller = new Botkit({
        // ...other options
    controller.on('message', async(bot, message) => {
        await bot.reply(message, 'I heard a message!');

    BotBuilder Basics

    Alternately, developers may choose to use HangoutsAdapter with BotBuilder. With BotBuilder, the adapter is used more directly with a webserver, and all incoming events are handled as Activities.

    const adapter = new HangoutsAdapter({
        token: process.env.GOOGLE_TOKEN,
        google_auth_params: {
            credentials: process.env.GOOGLE_CREDS
    const server = restify.createServer();
    server.use(restify.plugins.bodyParser());'/api/messages', (req, res) => {
         adapter.processActivity(req, res, async(context) => {
             await context.sendActivity('I heard a message!');

    Class Reference

    Event List

    Botkit will emit the following events:

    Event Description
    message a message from a user received in a shared channel
    card_clicked a user clicked a button on a card attachment
    direct_message a message from a user received in a private 1:1 with the bot
    bot_room_join the bot joined a new room
    bot_dm_join a new 1:1 with a user has been created
    bot_room_leave the bot has been removed from a room
    bot_dm_leave a 1:1 with a user has been closed

    Calling Google APIs

    This package exposes a pre-configured Google API client for developers who want to use one of the many available API endpoints.

    In Botkit handlers, the bot worker object passed into all handlers will contain a bot.api field that contains the client, preconfigured and ready to use.

    controller.on('message', async(bot, message) {
        // get a list of the members of a room
        let members = await bot.api.spaces.members.get({name:});
        // .. do stuff

    Botkit Extensions

    In Botkit handlers, the bot worker for Hangouts contains all of the base methods as well as the following platform-specific extensions:

    Use cards

    Botkit will automatically construct your outgoing messages according to Google's specifications. Google Hangouts supports card attachments with buttons.

    To use card attachments, add the cards field to the outgoing message object used to create the reply:

    await bot.reply(message, {
        text: 'Pick a card!',
        cards: [
                // card object

    Reply in a new thread

    In Google Hangouts, messages are organized into threads. Botkit provides specialized methods for cases where a bot's reply should create a new thread, or for when a bot should conduct an entire conversation in new/separate thread.

    Respond to card_clicked events

    When a button in an card attachment is clicked, Google sends a special event that requires a special response. Botkit will emit a card_clicked event, which should be responded to using either bot.replyWithUpdate() or bot.replyWithNew().

    See Google doc for interactive cards →.

    Update and remove messages

    Google Hangouts supports updating and deleting messages. Do so with the following convenience methods:
