App Installation

This sample app demonstarte the installation lifecycle for Teams Apps which includes create, update delete Apps

Interaction with app

Prerequisites

  • Microsoft Teams is installed and you have an account (not a guest account)
  • To test locally, NodeJS must be installed on your development machine (version 16.14.2 or higher)
  • ngrok or equivalent tunneling solution
  • M365 developer account or access to a Teams account with the

Setup

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

    • Your app must be registered in the Azure AD portal to integrate with the Microsoft identity platform and call Microsoft Graph APIs. See Register an application with the Microsoft identity platform.
    • You need to add following permissions mentioned in the below screenshots to call respective Graph API

  2. Setup for Bot

  • In Azure portal, create a Azure Bot resource.
  • 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 app registration, you will create an App ID and App password - make sure you keep these for later.

  1. Setup NGROK

    • Run ngrok - point to port 3978
    ngrok http -host-header=rewrite 3978

  2. Setup for code

  • Clone the repository

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

  • Update the .env configuration for the bot to use the ClientID and ClientSecret. (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.)

  • In a terminal, navigate to `samples/graph-app-installation-lifecycle/nodejs

  • Install modules

    npm install

  • Run your bot at the command line:

    npm start
  1. Setup Manifest for Teams

  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./Manifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok.io then your domain-name will be 1234.ngrok.io.
    • Zip up the contents of the Manifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

  • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

    • Go to Microsoft Teams. From the lower left corner, select Apps
    • From the lower left corner, choose Upload a custom App
    • Go to your project directory, the ./Manifest folder, select the zip folder, and choose Open.
    • Select Add in the pop-up dialog box. Your app is uploaded to Teams.
