Receive Channel messages with RSC permissions: Manifest

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

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

2. Setup for Bot

• Register a AAD aap registration in Azure portal.
• Also, register a bot with Azure Bot Service, following the instructions here.
• Ensure that you've enabled the Teams Channel
• While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint.

3. Setup Ngrok

• 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

4. Setup for code

• Clone the repository

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

• Modify the /appsettings.json and fill in the following details:

  • {{BOT-ID}} - Generated from Step 1 while doing AAd app registration in Azure portal.
  • {{BOT-PASSWORD}} -Generated from Step 1, also referred to as Client secret

• Run in Visual Studio

  • Launch Visual Studio
  • File -> Open -> Project/Solution
  • Navigate to ReceiveMessagesWithRSC folder
  • Select ReceiveMessagesWithRSC.csproj file
  • Press F5 to run the project

5. 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 bot earlier) everywhere you see the place holder string <<YOUR-MICROSOFT-APP-ID>> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json) also update the <<DOMAIN-NAME>> with the tunnel URL`

   • Edit the manifest.json for <<MANIFEST-ID>> replace it with any GUID using guid generator.

   • Edit the manifest.json for webApplicationInfo resource "api://botid-{{MicrosoftAppId}}" with MicrosoftAppId. E.g. "api://botid-{{MicrosoftAppId}}".

   • Zip up the contents of the AppManifest folder to create a manifest.zip

   • Sideload in a team to test

     • Select or create a team
     • Select the ellipses ... from the left pane. The drop-down menu appears.
     • Select Manage Team, then select Apps
     • Then select Upload a custom app from the lower right corner.
     • Then select the manifest.zip file from AppManifest, and then select Add to add the bot to your selected team.

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