Using Custom API bot can't post action card in Microsoft Teams channel using Bot framework

Question

I have to send actionable card from bot when I call my API then that API will push action card throught Bot in microsoft teams channel where I will pass channel ID and service URL

Currently I am successfully able to send Simple message into Microsoft teams channel using custom API ie working for send simple messages. But while sending action card it gives exception such as,

{"Activity resulted into multiple skype activities"}

As mentioned here in documentation :

Teams does not support SuggestedActions

So I update my code Its works now :)

    public async Task<HttpResponseMessage> PostClause(ClauseRequest clauseRequest)
    {
        try
        {
            var channelId = "19:cf4306bb3aff4996.......@thread.skype";
            var serviceURL = "https://smba.trafficmanager.net/apac-client-ss.msg/";
            var connector = new ConnectorClient(new Uri(serviceURL));
            var channelData = new Dictionary<string, string>();
            channelData["teamsChannelId"] = channelId;
            IMessageActivity newMessage = Activity.CreateMessageActivity();
            newMessage.Type = ActivityTypes.Message;


            var good = new CardAction("invoke", "Good", null, "{\"invokeValue\": \"Good\"}");
            var bad = new CardAction("invoke", "Bad", null, "{\"invokeValue\": \"Bad\"}");
            var card = new HeroCard("How are you today?", null, null, null, new List<CardAction> { good, bad }).ToAttachment();


            newMessage.Attachments.Add(card);

            ConversationParameters conversationParams = new ConversationParameters(
                isGroup: true,
                bot: null,
                members: null,
                topicName: "Test Conversation",
                activity: (Activity)newMessage,
                channelData: channelData);
            MicrosoftAppCredentials.TrustServiceUrl(serviceURL, DateTime.MaxValue);
            await connector.Conversations.CreateConversationAsync(conversationParams);
            var response = Request.CreateResponse(HttpStatusCode.OK);
            return response;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

I think this would have worked as well:

new CardAction(){ Title = "Approve", Type="ImBack", Value="Approve" },  
new CardAction(){ Title = "Decline", Type="ImBack", Value="Decline" }

according to this snippet in this example

CardAction plButton = new CardAction()
{
Value = $"https://en.wikipedia.org/wiki/{cardContent.Key}",
Type = "openUrl",
Title = "WikiPedia Page"
};
