Teams Messaging Extensions Action Preview

Bot Framework v4 Teams Messaging Extension Action Preview sample.

This Messaging Extension has been created using Bot Framework.

  • It shows how to create a simple card based on parameters entered by the user from a Task Module.
  • It also displays the scenario where a Bot sends messages on behalf of a User. Attributing the message to that user can help with engagement and showcase a more natural interaction flow.

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

Prerequisites

  • Java 1.8+
  • Install Maven
  • An account on Azure if you want to deploy to Azure.
  • Microsoft Teams is installed and you have an account
  • ngrok or equivalent tunnelling solution

To try this sample

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.

  • Run ngrok - point to port 3978

    ngrok http -host-header=rewrite 3978

  • Create Bot Framework registration resource in Azure

  • Update the resources/application.properties 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.)

  • 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)
    • Zip up the contents of the teamsAppManifest folder to create a manifest.zip
    • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

  • From the root of this project folder:

    • Build the sample using mvn package
    • Unless done previously, install the packages in the local cache by using mvn install
    • Run it by using java -jar .\target\bot-teams-messaging-extensions-action-preview-sample.jar

Interacting with the bot in Teams

Note the manifest.json specifies that this bot will be available in "personal", "team" and "groupchat" scopes and the command will be available in the "commandBox", "compose" and "message" context.

Click the Messaging Extension icon in the Compose Box's Messaging Extension menu.

Deploy the bot to Azure
