Send task request using Universal Adaptive Cards in a group chat

This sample shows a feature where:

  1. Requester : Can request for any task approval from manager by initiating a request in group chat using bot command request and only requester can edit the request card.
  2. Manager : Can see the request raised by user in the same group chat with an option of approve or reject.
  3. Others: Other members in the group chat can see the request details only.

Prerequisites

  • .NET Core SDK version 6.0

    determine dotnet version

    dotnet --version

  • Ngrok (For local environment testing) Latest (any other tunneling software can also be used)

    run ngrok locally

    ngrok http -host-header=localhost 3978

  • Teams Microsoft Teams is installed and you have an account

Setup

Setup for Bot

  • In Azure portal, create a Azure Bot resource.

    • For bot handle, make up a name.
    • Select "Use existing app registration" (Create the app registration in Azure Active Directory beforehand.)
    • If you don't have an Azure account create an Azure free account here

  • While registering the bot, use https://<your_ngrok_url>/api/messages as the messaging endpoint.

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

Register your Teams Auth SSO with Azure AD

  1. Register your app with Microsoft identity platform via the Azure AD portal

  2. Clone the repository

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

  3. Open the code in Visual Studio

    • File -> Open -> Project/Solution
    • Navigate to folder where repository is cloned then samples/bot-request-approval/csharp/BotRequestApproval.sln

  4. Run ngrok - point to port 3978

    # ngrok http -host-header=rewrite 3978

  5. Setup and run the bot from Visual Studio: Modify the appsettings.json and fill in the following details:

    • MicrosoftAppId - Generated from Step 1 (Application (client) ID)is the application app id
    • MicrosoftAppPassword - Generated from Step 1, also referred to as Client secret
    • Press F5 to run the project

  6. Setup Manifest for Teams

  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./AppPackage 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 AppPackage 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 ./AppPackage folder, select the zip folder, and choose Open.
    • Select Add in the pop-up dialog box. Your app is uploaded to Teams.
