AdaptiveCards with PostBack button - bots

Question

I am trying to replace a HeroCard that has multiple CardAction buttons. I would like to use AdaptiveCards, however, I don't see any documentation that states how to enable postBack from an AdaptiveCard button. I see open browser, and what not, but no postBack.
Is this supported yet?
var cardButtons = new List<CardAction>();
var yesAction = new CardAction()
{
Value = "Yes",
Type = "postBack",
Title = "Yes"
};
cardButtons.Add(yesAction);
var noAction = new CardAction()
{
Value = "Nope",
Type = "postBack",
Title = "No, I'll try it"
};
cardButtons.Add(noAction);
var plCard = new HeroCard()
{
Title = $"Are you sure?",
Buttons = cardButtons
};

Answer 1

Have you tried SubmitAction?
var noAction = new CardAction()
{
Value = "Nope",
Type = SubmitAction.TYPE,
Title = "No, I'll try it"
};

This code renders correctly, even seems to send information back to the bot. But still cannot figure out how to read the data back on the resuming function:
var card = new AdaptiveCard();
card.Body.Add(
new ColumnSet() {
Columns = new List<Column>() {
new Column() {
SelectAction = new SubmitAction() { Data = 3, Title = "Good" },
Items = new List<CardElement>() { new Image() { Url = GeneralStrings.Feedback03 } }
},
new Column() {
SelectAction = new SubmitAction() { Data = 2, Title = "Average" },
Items = new List<CardElement>() { new Image() { Url = GeneralStrings.Feedback02 } }
},
new Column() {
SelectAction = new SubmitAction() { Data = 1, Title = "Bad" },
Items = new List<CardElement>() { new Image() { Url = GeneralStrings.Feedback01 } }
}
}
});
var attachemnt = new Attachment() { ContentType = AdaptiveCard.ContentType, Content = card };
var message = context.MakeMessage();
message.Attachments.Add(attachemnt);
await context.PostAsync(message);
context.Wait<Activity>(this.AfterAskFeedback);
