    This package contains an adapter that communicates directly with the Vonage Messages 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 Vonage Messages API.

    Before you Begin

    You'll neeed to have a Vonage API account, a Vonage Virtual Number, install then run NGROK and setup webhooks for the Messages API with the NGROK URL. You can find clear instructions here.

    Use VonageAdapter

    VonageAdapter provides a translation layer to the Microsoft Bot Framework, so that bot developers can connect to Vonage Messages API via using the Vonage Server SDk Client.

    Node.js Module

    This is a npm module in TypeScript, which is "importable" in JavaScript and TypeScript

    Install Package

    Most npm modules come without a Type definition, so TypeScript developers will have to run an additional npm i @types/<module_name> -D command to be able to use the npm module

    Add this package to your project using npm:

    npm install --save botbuilder-adapter-vonage

    Import the adapter class into your code:

    const { VonageAdapter } = require("botbuilder-adapter-vonage");

    Quick start Demo

    Before proceeding, you'll have to complete the steps at Before you Begin, if not then please complete that. The code snippet below has the code to run the Demo. You can learn more by following the instructions to create a customized application template.

    Use the VonageAdapter to connect to the Microsoft Bot Framework via either Botkit or BotBuilder. Using BotBuilder with the VonageAdapter, would allow the adapter to be used more directly with a webserver, and all incoming events are handled as Activities.

    Example 1: VonageAdapter use with BotKit.

    // webhook-server.js
    "use strict";
    const express = require("express");
    const bodyParser = require("body-parser");
    const app = express();
    const port = 3000;
    app.use(bodyParser.urlencoded({ extended: true }));
    const { VonageAdapter } = require("botbuilder-adapter-vonage");
    const { Botkit } = require("botkit");
    const TO_NUMBER = process.env.TO_NUMBER;
    const FROM_NUMBER = process.env.FROM_NUMBER;
    const VONAGE_API_KEY = process.env.VONAGE_API_KEY;
    const VONAGE_API_SECRET = process.env.VONAGE_API_SECRET;
    const adapter = new VonageAdapter({
      to_number: TO_NUMBER,
      from_number: FROM_NUMBER,
      apiKey: VONAGE_API_KEY,
      apiSecret: VONAGE_API_SECRET,
      applicationId: VONAGE_APPLICATION_ID,
    const controller = new Botkit({
      webhook_uri: '/webhooks/inbound-message',
    controller.hears(".*", "message", async (bot, message) => {
      await bot.reply(message, "I heard: " + message.text);
    controller.on("event", async (bot, message) => {
      await bot.reply(message, "I received an event of type " + message.type);
    });"/webhooks/message-status", (req, res) => {
    });"/webhooks/dir", (req, res) => {
    app.listen(port, () => {
      console.log(`🌏 Server running at http://localhost:${port}`);

    Run ngrok, then set the new ngrok URL to your Vonage SMS settings, Virtual number and Vonage Application.

    ngrok http 3000

    Start the webhook server, then from your phone send a text to your Virtual Number. You should get a reply "I heard msg-you-sent!"

    nodemon webhook-server.js

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

    const adapter = new VonageAdapter({
      to_number: process.env.TO_NUMBER,
      from_number: process.env.FROM_NUMBER,
      apiKey: process.env.API_KEY,
      apiSecret: process.env.API_SECRET,
      applicationId: process.env.APP_ID,
      privateKey: process.env.PRIVATE_KEY_PATH,
    const controller = new Botkit({
      webhook_uri: '/webhooks/inbound-message',
    controller.on("message", async (bot, message) => {
      await bot.reply(message, "I heard a message!");

    BotBuilder Basics

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

    Example 2: VonageAdapter used with Botbuilder

    const adapter = new VonageAdapter({
      to_number: process.env.TO_NUMBER,
      from_number: process.env.FROM_NUMBER,
      apiKey: process.env.API_KEY,
      apiSecret: process.env.API_SECRET,
      applicationId: process.env.APP_ID,
      privateKey: process.env.PRIVATE_KEY_PATH,
    const server = restify.createServer();
    server.use(restify.plugins.bodyParser());"/webhooks/inbound-message", (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

    Calling Vonage Message APIs

    This package exposes a pre-configured Vonage Server 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

    Botkit Extensions

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

    Use attachments, quick replies and other rich message features

    Botkit will automatically construct your outgoing messages according to Vonage's specifications. To use attachments, quick replies or other features, add them to the message object used to create the reply:


    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.
