Teams Conversation Bot

This sample app demonstrates how to handle various bot conversation events in Microsoft Teams, including read receipts and adaptive card interactions. It showcases capabilities such as immersive reader support and message update tracking, making it ideal for personal, group, and team chat scopes.

Bot Framework v4 Conversation Bot sample for Teams (Messages in bot conversations).

This bot has been created using Bot Framework. This sample shows how to incorporate basic conversational flow into a Teams application. It also illustrates a few of the Teams specific calls you can make from your bot.

This sample is a Spring Boot app and uses the Azure CLI and azure-webapp Maven plugin to deploy to Azure.

Included Features

• Bots
• Adaptive Cards
• Teams Conversation Events
• Immersive Reading Support for Cards

Interaction with bot

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Teams Conversation Bot: Manifest

Prerequisites

• Intall Java 1.8+ Java
• Install Maven
• Setup for Java and Maven Setup
• An account on Azure if you want to deploy to Azure.
• Microsoft Teams is installed and you have an account
• dev tunnel or ngrok latest version 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. 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

2. 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

   In the new Azure Bot resource in the Portal,

   • Ensure that you've enabled the Teams Channel
   • In Settings/Configuration/Messaging endpoint, enter the current https URL you were given by running the tunneling application. Append with the path /api/messages

3. Clone the repository

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

4. Update the resources/application.properties file configuration in your project, 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.)

5. From the root of this project folder: (samples/bot-conversation/java)

   • Open a terminal and build the sample using mvn package command
   • Install the packages in the local cache by using mvn install command in a terminal
   • Run it by using java -jar .\target\bot-teams-conversation-sample.jar command in a terminal

6. This step is specific to Teams.

   • Edit the manifest.json contained in the teamsAppManifest 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)
   • Edit the manifest.json for validDomains with base Url 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 TeamsAppManifest 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 Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)
   • Add the app to personal/team/groupChat scope (Supported scopes)

Running the sample

You can interact with this bot by sending it a message, or selecting a command from the command list. The bot will respond to the following strings.

1. Show Welcome

• Result: The bot will send the welcome card for you to interact with
• Valid Scopes: personal, group chat, team chat

2. MentionMe

• Result: The bot will respond to the message and mention the user
• Valid Scopes: personal, group chat, team chat

3. MessageAllMembers

• Result: The bot will send a 1-on-1 message to each member in the current conversation (aka on the conversation's roster).
• Valid Scopes: personal, group chat, team chat

You can select an option from the command list by typing @TeamsConversationBot into the compose message area and What can I do? text above the compose area.

Avoiding Permission-Related Errors

You may encounter permission-related errors when sending a proactive message. This can often be mitigated by using MicrosoftAppCredentials.TrustServiceUrl(). See the documentation for more information.
