Adaptive card popup

Brass Contributor



I want to buld an adaptive card with a button in a teams channel.

When user press the butto

A popup window should open with an embed powerapp. 


I think this is more userfriendly than pointing the button to a tab in the channel. 


Is this possible?

Yes, it is possible to build an Adaptive Card with a button in a Teams channel that opens a popup window with an embedded Power App. This can provide a more user-friendly experience compared to pointing the button to a tab in the channel.

To achieve this, you can use Task Modules in Microsoft Teams. Task modules allow you to create modal pop-up experiences in your Teams application. In the pop-up window, you can run your own custom HTML or JavaScript code or display an Adaptive Card.

Here's an example of how you can implement this:

  1. Create an Adaptive Card with a button:
  "type": "AdaptiveCard",
  "body": [
      "type": "TextBlock",
      "text": "Click the button to open the Power App"
  "actions": [
      "type": "Action.Submit",
      "title": "Open Power App",
      "data": {
        "action": "openPowerApp"
  1. In your bot or message extension, handle the openPowerApp action:
protected override async Task<TaskModuleResponse> OnTeamsMessagingExtensionSubmitActionAsync(ITurnContext<IInvokeActivity> turnContext, MessagingExtensionAction action, CancellationToken cancellationToken)
    if (action.CommandId == "openPowerApp")
        var taskModule = new TaskModuleContinueResponse
            Type = "continue",
            Value = new TaskModuleTaskInfo
                Title = "Power App",
                Height = "medium",
                Width = "medium",
                Url = "https://your-power-app-url"

        return taskModule.ToTaskModuleResponse();

    return null;
  1. When the user clicks the "Open Power App" button, the openPowerApp action is triggered. In the bot or message extension code, you can handle this action and return a TaskModuleContinueResponse with the URL of your Power App. This will open the Power App in a popup window.

By using Task Modules and Adaptive Cards, you can create a button in a Teams channel that opens a popup window with an embedded Power App. This provides a more user-friendly experience for your users.

Step 2 confuses me a bit. I think this is aoutside of my knowledge...

All i have done so far is to create the adaptive card.
Add a button and i know how to add the url to the button. But the step of creating a bot/app (message extension) where this code should be... i dont know?
