Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• dev tunnel or Ngrok (For local environment testing) latest version (any other tunneling software can also be used)

• 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 Microsoft Entra ID beforehand.)
  • If you don't have an Azure account create an Azure free account here

• While registering the bot, use https://<your_tunnel_domain>/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

   • Your app must be registered in the Azure AD portal. See Register an application with the Microsoft identity platform.

   • Ensure that you've enabled the Teams Channel

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 3978 --host-header="localhost:3978"

   Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

   devtunnel host -p 3978 --allow-anonymous

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 ./AppManifest 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-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
  • Zip up the contents of the AppManifest 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 ./AppManifest folder, select the zip folder, and choose Open.
  • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.
