Connect Botkit or BotBuilder to Twilio SMS.

This package contains an adapter that communicates directly with the Twilio 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 Twilio SMS.

Install Package

Add this package to your project using npm:

npm install --save botbuilder-adapter-twilio-sms

Import the adapter class into your code:

const { TwilioAdapter } = require('botbuilder-adapter-twilio-sms');

Get Started

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

Use TwilioAdapter in your App

TwilioAdapter provides a translation layer for Botkit and BotBuilder so that bot developers can connect to Twilio SMS and have access to the Twilio 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 Twilio.

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 TwilioAdapter options and example code can be found in the class reference docs.

const adapter = new TwilioAdapter({
    twilio_number: process.env.TWILIO_NUMBER,
    account_sid: process.env.TWILIO_ACCOUNT_SID,
    auth_token: process.env.TWILIO_AUTH_TOKEN,

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 TwilioAdapter with BotBuilder. With BotBuilder, the adapter is used more directly with a webserver, and all incoming events are handled as Activities.

const adapter = new TwilioAdapter({
    twilio_number: process.env.TWILIO_NUMBER,
    account_sid: process.env.TWILIO_ACCOUNT_SID,
    auth_token: process.env.TWILIO_AUTH_TOKEN,

const server = restify.createServer();
server.post('/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
picture_message a message with a picture attached

Calling Twilio APIs

This package exposes a pre-configured Twilio 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) {

    // create a message using the API directly
    let res = await bot.api.messages.create(my_message_object);


Botkit Extensions

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


Use this method to initiate a conversation with a user. After calling this method, any further actions carried out by the bot worker will happen with the specified user.

This can be used to create or resume conversations with users that are not in direct response to an incoming message, like those sent on a schedule or in response to external events.
