Create and send dialogs

You can create a modal dialog (referred as task module in TeamsJS v1.x) using an Adaptive Card or an embedded web view. To create a dialog, you must perform the process called the initial invoke request. This document covers the initial invoke request, payload activity properties when a dialog is invoked from 1:1 chat, group chat, channel (new post), channel (reply to thread), and command box.

The initial invoke request

In the process of the initial invoke request, your service receives an Activity object of type composeExtensions/fetchTask, and you must respond with a task object containing either an Adaptive Card or a URL to the embedded web view. Along with the standard bot activity properties, the initial invoke payload contains the following request metadata:

Example

The code for the initial invoke request is given in the following example:

Initial invoke request from a message

When your bot is invoked from a message, the value object in the initial invoke request must contain the details of the message that your message extension is invoked from. The reactions and mentions arrays are optional, and they are not present if there are no reactions or mentions in the original message. The following section is an example of the value object:

protected override async Task<MessagingExtensionActionResponse> OnTeamsMessagingExtensionFetchTaskAsync(ITurnContext<IInvokeActivity> turnContext, MessagingExtensionAction action, CancellationToken cancellationToken)

  var messageText = action.MessagePayload.Body.Content;
  var fromId = action.MessagePayload.From.User.Id;

Respond to the fetchTask

Respond to the invoke request with a task object that contains either a taskInfo object with the Adaptive Card or web URL, or a simple string message.

The schema for the taskInfo object is:

Respond to the fetchTask with an Adaptive Card

When using an Adaptive Card, you must respond with a task object with the value object containing an Adaptive Card.

Example

The following code section is an example to fetchTask response with an Adaptive Card:

protected override async Task<MessagingExtensionActionResponse> OnTeamsMessagingExtensionFetchTaskAsync(ITurnContext<IInvokeActivity> turnContext, MessagingExtensionAction action, CancellationToken cancellationToken)

      var fromId = action.MessagePayload.From.User.Id;
      placeholder = "Invoked from message";
  }

  var response = new MessagingExtensionActionResponse()
  {
    Task = new TaskModuleContinueResponse()
    {
      Value = new TaskModuleTaskInfo()
      {
        Height = "small",
        Width = "small",

Create a dialog with an embedded web view

When using an embedded web view, you must respond with a task object with the value object containing the URL to the web form that you want to load. The domains of any URL you want to load must be included in the validDomains array in your app's manifest. For more information on building your embedded web view, see the dialog documentation.

protected override async Task<MessagingExtensionActionResponse> OnTeamsMessagingExtensionFetchTaskAsync(ITurnContext<IInvokeActivity> turnContext, MessagingExtensionAction action, CancellationToken cancellationToken)
{
  string placeholder = "Not invoked from message";

  if (action.MessagePayload != null)
  {
      var messageText = action.MessagePayload.Body.Content;
      var fromId = action.MessagePayload.From.User.Id;
      placeholder = "Invoked from message";
  }

  var response = new MessagingExtensionActionResponse()
  {
    Task = new TaskModuleContinueResponse()
    {
      Value = new TaskModuleTaskInfo()
      {
        Height = "small",
        Width = "small",
        Title = "Example dialog",
        Url = "https://contoso.com/msteams/taskmodules/newcustomer",
        },
      },
    },
  };
  return response;
}

class TeamsMessagingExtensionsActionPreview extends TeamsActivityHandler {
  handleTeamsMessagingExtensionFetchTask(context, action) {
    return {
      task: {
        type: 'continue',
        value: {
          width: 500,
          height: 450,
          title: 'Task Module Fetch Example',
          url: 'https://contoso.com/msteams/taskmodules/newcustomer',
          fallbackUrl: 'https://contoso.com/msteams/taskmodules/newcustomer'
        }
      }
    };
  }
}

{
  "task": {
    "type": "continue",
    "value": {
      "title": "Dialog title",
      "height": 500,
      "width": "medium",
      "url": "https://contoso.com/msteams/taskmodules/newcustomer",
      "fallbackUrl": "https://contoso.com/msteams/taskmodules/newcustomer"
    }

Request to install your conversational bot

If the app contains a conversational bot, install the bot in the conversation and then load the dialog. The bot is useful to get additional context for the dialog. An example for this scenario is to fetch the roster to populate a people picker control or the list of channels in a team.

When the message extension receives the composeExtensions/fetchTask invoke, check if the bot is installed in the current context to facilitate the flow. For example, check the flow with a get roster call. If the bot is not installed, return an Adaptive Card with an action that requests the user to install the bot. The user must have the permission to install the apps in that location for checking. If the app installation is unsuccessful, the user receives a message to contact the administrator.

Example

The following code section is an example of the response:

{
  "type": "AdaptiveCard",
  "body": [
    {
      "type": "TextBlock",
      "text": "Looks like you haven't used Disco in this team/chat"
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "Continue",
      "data": {
        "msteams": {
          "justInTimeInstall": true
        }
      }
    }
  ],
  "version": "1.0"
}

After the installation of conversational bot, it receives another invoke message with name = composeExtensions/submitAction, and value.data.msteams.justInTimeInstall = true.

Example

The following code section is an example of the task response to the invoke:

{
  "value": {
    "commandId": "giveKudos",
    "commandContext": "compose",
    "context": {
      "theme": "default"
    },
    "data": {
      "msteams": {
        "justInTimeInstall": true
      }
    }
  },
  "conversation": {
    "id": "19:7705841b240044b297123ad7f9c99217@thread.skype"
  },
  "name": "composeExtension/submitAction",
  "imdisplayname": "Bob Smith"
}

The task response to the invoke must be similar to that of the installed bot.

Example

The following code section is an example of just-in time installation of app with Adaptive card:

private static Attachment GetAdaptiveCardAttachmentFromFile(string fileName)
  {
      //Read the card json and create attachment.
         string[] paths = { ".", "Resources", fileName };
         var adaptiveCardJson = File.ReadAllText(Path.Combine(paths));
         var adaptiveCardAttachment = new Attachment()
            {
                ContentType = "application/vnd.microsoft.card.adaptive",
                Content = JsonConvert.DeserializeObject(adaptiveCardJson),
            };
            return adaptiveCardAttachment;
        }
