Botmaster-messenger

Build Status Coverage Status npm-version license

This is the FB messenger integration for botmaster. It allows you to use your botmaster bot on FB Messenger

Botmaster is a lightweight chatbot framework. Its purpose is to integrate your existing chatbot into a variety of messaging channels - currently Facebook Messenger, Twitter DM and Telegram.

Documentation

Find the whole documentation for the Botmaster framework on: http://botmasterai.com/documentation/latest

Installing

yarn add botmaster-messenger

or

npm install --save botmaster-messenger

Getting your Credentials

If you don't already have these, follow the steps 1-4 on the Facebook Messenger guide: https://developers.facebook.com/docs/messenger-platform/guides/quick-start

In step 2, where you setup your webhook, no need to code anything. Just specify the webhook, enter any secure string you want as a verify token(verifyToken) and copy that value in the settings object. Also, click on whichever message [those are "update"s using botmaster semantics] type you want to receive from Messenger (message_deliveries, messages, message_postbacks etc...).

To find your Facebook App Secret (fbAppSecret), navigate to your apps dashboard and under App Secret click show, enter your password if prompted and then there it is.

Code

Example code using a single page for a bot. When using a single page, botmaster can be used as expected.

const Botmaster = require('botmaster');
const MessengerBot = require('botmaster-messenger');
const botmaster = new Botmaster();

const messengerSettings = {
  credentials: {
    verifyToken: 'YOUR verifyToken',
    pageToken: 'YOUR pageToken',
    fbAppSecret: 'YOUR fbAppSecret',
  },
  webhookEndpoint: 'webhook1234',
};

const messengerBot = new MessengerBot(messengerSettings);

botmaster.addBot(messengerBot);

botmaster.use({
  type: 'incoming',
  name: 'my-middleware',
  controller: (bot, update) => {
    return bot.reply(update, 'Hello world!');
  }
});

multi-page bot example

const Botmaster = require('botmaster');
const MessengerBot = require('botmaster-messenger');
const botmaster = new Botmaster();

const messengerSettings = {
  credentials: {
    verifyToken: 'YOUR_VERIFY_TOKEN',
    fbAppSecret: 'YOUR_FB_APP_SECRET',
    pages: {
      'YOUR_PAGE_ID_1': {
        pageToken: 'YOUR_PAGE_TOKEN_1',
      },
      'YOUR_PAGE_ID_2': {
        pageToken: 'YOUR_PAGE_TOKEN_2',
      },
    },
  },
  webhookEndpoint: 'webhook1234',
};

const messengerBot = new MessengerBot(messengerSettings);

botmaster.addBot(messengerBot);

botmaster.use({
  type: 'incoming',
  name: 'my-middleware',
  controller: (bot, update) => {
    // 1) if you simply want to respond as the page that received the update.
    bot.reply(update, 'Hello World');
    // 2) or if you want to specify another page to response as, you can always set
    // the messageToSend.sender.id param as some other pageId as such.
    const messageToSend = bot.createOutgoingMessageFor(update.sender.id); // or any other page-scoped userId you know is using your page
    messageToSend.addText('Hello World');
    messageToSend.sender = {
      id: 'SOME_PAGE_ID', // update.sender.id would be this page. But you can set it to something else.
    };
    return bot.sendMessage(messageToSend);
  }
});

Contributing

In order to contribute, you will need to make sure the tests run on your local machine. To do so, follow these steps:

  1. Create a ./tests/_config.js file that looks like this:
'use strict';

const config = {
  messengerCredentials: () => ({
    verifyToken: 'YOUR_VERIFY_TOKEN',
    pageToken: 'YOUR_PAGE_TOKEN',
    fbAppSecret: 'YOUR_FB_APP_SECRET',

    },
  }),

  messengerUserId: () => 'YOUR_USER_ID_FOR_THIS_PAGE', // who to send messages to in tests (most probably one of your accounts)
  messengerBotId: () => 'YOUR_BOT_ID', // the id of the bot (as sent in message updates). I.E. your page id
};

module.exports = config;
