Adaptive Card button should return "MessagingExtensionActionResponse"

[maheshkumargunasekaran]

Hi All,

Our application used to send notification to MS Teams users via bot. The application has been developed through C#. We have created a button with the below code.

Actions =
{
new AdaptiveSubmitAction()
{
Type = AdaptiveSubmitAction.TypeName,
Title = "Click Here",
},
},

By default, it invoked OnMessageActivityAsync(). Later we have added below piece of code in the button property.

Data = new TaskModuleDetail<string>() { Data = "SignIn", CommandId = "SignIn" },

In the class file of TaskModuleDetail, we have defined the Type as below.

public object Type { get; set; } = JsonConvert.DeserializeObject("{\"type\": \"task/fetch\" }");

Hence it is redirecting to OnTeamsTaskModuleFetchAsync().

But am expecting the click event of button should hit OnTeamsMessagingExtensionFetchTaskAsync() which returns MessagingExtensionActionResponse as i need to do launch an URL and perform authentication. 

Could someone help me to fix it?

Hi, I don't think you can can trigger OnTeamsMessagingExtensionFetchTaskAsync() on submit of adaptive card button. This method is invoked when we try to trigger messaging extension. https://docs.microsoft.com/en-us/dotnet/api/microsoft.bot.builder.teams.teamsactivityhandler.onteams...

Messaging extension can only be triggered from compose box, search bar or message actions. You can refer below document.
