Responding with a Card from an API Callback

[srozga]

It is unclear how to response with a card from a callback. App.ts refers to BB.Activity, but that type isn't available in that namespace. Tried returning the result of calling BB.CardFactory.heroCard but nothing was sent back to the emulator.
Thanks

Might be easiest to just share an example. Here is an API callback that renders a carousel of cocktail cards:

cl.AddAPICallback("ShowCocktails", async (memoryManager: ClientMemoryManager) => {

let cocktails = memoryManager.EntityValueAsList("cocktails")

let attachments = []

for (let id of cocktails) {
    let cocktail = await getCocktailById(id)
    if (cocktail) {
        let card = renderDrink(cocktail);
        attachments.push(BB.CardFactory.adaptiveCard(card))
    }
}

const message = BB.MessageFactory.list(attachments)
message.text = undefined
message.attachmentLayout = "carousel"

return message

})

export function renderDrink(drink: IDrink) {

let facts = [];
if (drink.strIngredient1) {
    facts.push({
        title: drink.strIngredient1,
        value: drink.strMeasure1
    })
}
if (drink.strIngredient2) {
    facts.push({
        title: drink.strIngredient2,
        value: drink.strMeasure2
    })
}
if (drink.strIngredient3) {
    facts.push({
        title: drink.strIngredient3,
        value: drink.strMeasure3
    })
}
if (drink.strIngredient4) {
    facts.push({
        title: drink.strIngredient4,
        value: drink.strMeasure4
    })
}
if (drink.strIngredient5) {
    facts.push({
        title: drink.strIngredient5,
        value: drink.strMeasure5
    })
}
let factSet = {
    type: "FactSet",
    facts: facts
}

let items = [];
items.push(
    {
        type: "TextBlock",
        text: drink.strDrink,
        weight: "bolder",
        size: "extraLarge",
        spacing: "none"
});
items.push({
    type: "TextBlock",
    text: drink.strGlass,
    size: "small",
    wrap: true
})

let column1 = {
    type: "Column",
    width: 1,
    items: items
}

let column2 = {
    type: "Column",
    width: 1,
    items: [
        {
            type: "Image",
            url: drink.strDrinkThumb
        }
    ]
}

let body = [];
body.push({
    type: "ColumnSet",
    columns: [column1, column2]
})
body.push({
    type: "TextBlock",
    text: drink.strInstructions,
    size: "small",
    wrap: true
})
body.push(factSet)

let actions = [];
actions.push({
    type: "Action.Submit",
    title: "Make It!",
    data: { submit: "Make It" }
})
actions.push({
    type: "Action.Submit",
    title: "Something Else",
    data: { submit: "Something Else" }
})

let acard = {
    $schema: "http://adaptivecards.io/schemas/adaptive-card.json",
    type: "AdaptiveCard",
    version: "1.0",
    body: body,
    actions: actions
}
return acard;

}

Got it! MessageFactory is what I was looking for. Thanks!
