Teams Auth Bot

Bot Framework v4 bot using Teams authentication

This bot has been created using Bot Framework, it shows how to get started with authentication in a bot for Microsoft Teams.

The focus of this sample is how to use the Bot Framework support for oauth in your bot. Teams behaves slightly differently than other channels in this regard. Specifically an Invoke Activity is sent to the bot rather than the Event Activity used by other channels. This Invoke Activity must be forwarded to the dialog if the OAuthPrompt is being used. This is done by subclassing the ActivityHandler and this sample includes a reusable TeamsActivityHandler. This class is a candidate for future inclusion in the Bot Framework SDK.

The sample uses the bot authentication capabilities in Azure Bot Service, providing features to make it easier to develop a bot that authenticates users to various identity providers such as Azure AD (Azure Active Directory), GitHub, Uber, etc. The OAuth token is then used to make basic Microsoft Graph queries.

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.

Prerequisites

  • Microsoft Teams is installed and you have an account (not a guest account)
  • ngrok or equivalent tunnelling solution

Setup

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

  2. Setup for Bot Create Bot Framework registration resource in Azure

    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 -host-header=rewrite 3978
  4. Setup for code

  • Clone the repository

    git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git
  • In a terminal, navigate to Microsoft-Teams-samples\samples\bot-teams-authentication\python folder

  • Activate your desired virtual environment

  • In the terminal, type pip install -r requirements.txt

  • Run ngrok - point to port 3978

    ngrok http --host-header=rewrite 3978
  • Update the config.py configuration for the bot to use the Microsoft App Id and App Password from the Bot Framework registration. (Note the App Password is referred to as the "client secret" in the azure portal and you can always create a new client secret anytime.)

  1. Setup Manifest for Teams
  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./teams_app_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 teams_app_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 ./teams_app_manifest folder, select the zip folder, and choose Open.
    • Select Add in the pop-up dialog box. Your app is uploaded to Teams.
  • Run your bot with python app.py

Note this manifest.json specified that the bot will be installed in a "personal" scope only. Please refer to Teams documentation for more details.

Running the sample

You can interact with this bot by sending it a message. The bot will respond by requesting you to login to AAD, then making a call to the Graph API on your behalf and returning the results.
