Install app using barcode sample

This sample demos app installation using QR code.

The user can Generate a new QR code (contains app id information) and then use Install action to scan and install the app.

Currently, Microsoft Teams support for QR or barcode scanner capability is only available for mobile clients

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• NodeJS
• ngrok or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

To try this sample

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. Setup for Bot SSO

In Azure portal, create a Bot Framework registration resource.

• Ensure that you've enabled the Teams Channel

Add the following permission in app registration

2. Run your bot sample

1. Clone the repository

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

2. In a terminal, navigate to samples/app-installation-using-qr-code/nodejs

3. Install modules

   npm install

4. Run ngrok - point to port 3978

   ngrok http -host-header=rewrite 3978

5. Update the .env configuration for the bot to use the MicrosoftAppId and MicrosoftAppPassword, connectionName from the Bot Framework registration and BaseUrl with application base url. For e.g., your ngrok url. (Note the MicrosoftAppId is the AppId created in step 1 (Setup for Bot SSO), the MicrosoftAppPassword is referred to as the "client secret" in step 1 (Setup for Bot SSO) and you can always create a new client secret anytime.)

6. Run your app

   npm start

• Manually update the manifest.json

  • 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")

  IMPORTANT: The manifest file in this app adds "token.botframework.com" to the list of validDomains. This must be included in any bot that uses the Bot Framework OAuth flow.
