Bots/Messaging Extension

Bots allow users to interact with your web service through text, interactive cards, and task modules. Messaging extensions allow users to interact with your web service through buttons and forms in the Microsoft Teams client. They can search, or initiate actions, in an external system from the compose message area, the command box, or directly from a message.

Included Features

  • Bots
  • Message Extensions
  • Action Commands

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Messaging Extension: Manifest

Prerequisites

Dependencies

Setup

  1. Register a new application in the Azure Active Directory – App Registrations portal.

  2. Setup for Bot

    • Also, register a bot with Azure Bot Service, following the instructions here.
    • Ensure that you've enabled the Teams Channel
    • While registering the bot, use https://<your_ngrok_url>/api/messages as the messaging endpoint.

    NOTE: When you create your app registration, you will create an App ID and App password - make sure you keep these for later.

  3. Setup NGROK

  • Run ngrok - point to port 3978

    ngrok http 3978 --host-header="localhost:3978"
  1. Setup for code

  • Clone the repository

    git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

-In a terminal, navigate to samples/msgext-action-quickstart/js

  • Build npm install

  • Update the .env configuration for the bot to use the MicrosoftAppId and MicrosoftAppPassword. (Note the MicrosoftAppId is the AppId created in step 1 (Setup for Bot), the MicrosoftAppPassword is referred to as the "client secret" in step 1 (Setup for Bot) and you can always create a new client secret anytime.)

  1. Run your app

    npm start

  2. Setup Manifest for Teams

  • This step is specific to Teams.
    • Edit the manifest.json contained in the appPackage/ folder to replace with your MicrosoftAppId (that was created in step1.1 and is the same value of MicrosoftAppId in .env file) everywhere you see the place holder string {MicrosoftAppId} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Zip up the contents of the appPackage/ folder to create a manifest.zip
    • Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Upload a custom app")

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.
