Teams Tab SSO Authentication

Tabs are Teams-aware webpages embedded in Microsoft Teams. Personal tabs are scoped to a single user. They can be pinned to the left navigation bar for easy access.

Prerequisites

ngrok

Teams needs to access your tab from a publically accessible URL. If you are running your app in localhost, you will need to use a tunneling service like ngrok.

  • Run ngrok and point it to localhost:
  • ngrok http https://localhost:3000

Note: It may be worth purchasing a basic subscription to ngrok so you can get a fixed subdomain ( see the --subdomain ngrok parameter)

IMPORTANT: If you don't have a paid subscription to ngrok, you will need to update your Azure AD app registration application ID URI and redirect URL ( See steps 5 and 13 here ) everytime you restart ngrok.

Build and Run

In the root directory, execute:

npm install

npm start

Deploy to Teams

Start debugging the project by hitting the F5 key or click the debug icon in Visual Studio Code and click the Start Debugging green arrow button.

NOTE: First time debug step

On the first time running and debugging your app you need allow the localhost certificate. After starting debugging when Chrome is launched and you have installed your app it will fail to load.

  • Open a new tab in the same browser window that was opened
  • Navigate to https://localhost:3000/tab
  • Click the Advanced button
  • Select the Continue to localhost
  • You may also need to enable popups in the browser to see the auth consent page.

NOTE: Debugging

Ensure you have the Debugger for Chrome/Edge extension installed for Visual Studio Code from the marketplace.
