Microsoft Bot Framework Connector for Node.js

Within the Bot Framework, the Bot Connector service enables your bot to exchange messages with users on channels that are configured in the Bot Framework Portal.


  • Node.js version: 6.x.x or higher

How to Install

npm install botframework-connector

How to Use


Your bot communicates with the Bot Connector service using HTTP over a secured channel (SSL/TLS). When your bot sends a request to the Connector service, it must include information that the Connector service can use to verify its identity.

To authenticate the requests, you'll need configure the Connector with the App ID and password that you obtained for your bot during registration and the Connector will handle the rest.

More information:


Client creation (with authentication), conversation initialization and activity send to user.

var { ConnectorClient, MicrosoftAppCredentials } = require('botframework-connector');

async function connectToSlack() {
    var credentials = new MicrosoftAppCredentials('<your-app-id>', '<your-app-password>');

    var botId = '<bot-id>';
    var recipientId = '<user-id>';

    var client = new ConnectorClient(credentials, { baseUri: '' });

    var conversationResponse = await client.conversations.createConversation({
        bot: { id: botId },
        members: [
            { id: recipientId }
        isGroup: false

    var activityResponse = await client.conversations.sendToConversation(, {
        type: 'message',
        from: { id: botId },
        recipient: { id: recipientId },
        text: 'This a message from Bot Connector Client (NodeJS)'

    console.log('Sent reply with ActivityId:',;

Simple EchoBot Example (source code)

EchoBot is a minimal bot that receives message activities and replies with the same content. The sample shows how to use restify/express for listening to activities and the ConnectorClient for sending activities.
