Cards

Send rich interactive cards with buttons, fields, and images across all platforms.

Cards let you send structured, interactive messages that render natively on each platform — Block Kit on Slack, Adaptive Cards on Teams, and Google Chat Cards.

Setup

Configure your tsconfig.json to use the Chat SDK JSX runtime:

tsconfig.json

{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "chat"
  }
}

Or use a per-file pragma:

lib/bot.tsx

/** @jsxImportSource chat */

Basic card

lib/bot.tsx

import { Card, CardText, Button, Actions } from "chat";

await thread.post(
  <Card title="Order #1234">
    <CardText>Your order has been received!</CardText>
    <Actions>
      <Button id="approve" style="primary">Approve</Button>
      <Button id="reject" style="danger">Reject</Button>
    </Actions>
  </Card>
);

Components

Card

The top-level container. Accepts title and optional subtitle.

lib/bot.tsx

<Card title="My Card" subtitle="Optional subtitle">
  {/* children */}
</Card>

CardText

Renders formatted text. Supports a subset of markdown.

lib/bot.tsx

<CardText>**Bold** and _italic_ text</CardText>
<CardText style="bold">Bold section header</CardText>

Use CardText instead of Text when using JSX to avoid conflicts with React's built-in types.

Section

Groups related content together.

lib/bot.tsx

<Section>
  <CardText>Section content here</CardText>
</Section>

Fields

Renders key-value pairs in a compact layout.

lib/bot.tsx

<Fields>
  <Field label="Name" value="John Doe" />
  <Field label="Role" value="Developer" />
  <Field label="Team" value="Platform" />
</Fields>

Button

An action button that triggers an onAction handler.

lib/bot.tsx

<Button id="approve" style="primary">Approve</Button>
<Button id="reject" style="danger">Reject</Button>
<Button id="details">View Details</Button>

The id maps to your onAction handler. Optional value passes extra data:

lib/bot.tsx

<Button id="report" value="bug">Report Bug</Button>

LinkButton

Opens an external URL. No onAction handler needed.

lib/bot.tsx

<LinkButton url="https://example.com/order/1234">View Order</LinkButton>

Actions

Container for buttons and interactive elements.

lib/bot.tsx

<Actions>
  <Button id="approve" style="primary">Approve</Button>
  <Button id="reject" style="danger">Reject</Button>
  <LinkButton url="https://example.com">View</LinkButton>
</Actions>

Select

Inline dropdown menu.

lib/bot.tsx

<Actions>
  <Select id="priority" label="Priority" placeholder="Select priority">
    <SelectOption label="High" value="high" description="Urgent tasks" />
    <SelectOption label="Medium" value="medium" />
    <SelectOption label="Low" value="low" />
  </Select>
</Actions>

Selection triggers an onAction handler with the id as the actionId and the selected value.

RadioSelect

Radio button group for mutually exclusive choices.

lib/bot.tsx

<Actions>
  <RadioSelect id="status" label="Status">
    <SelectOption label="Open" value="open" />
    <SelectOption label="In Progress" value="in_progress" />
    <SelectOption label="Done" value="done" />
  </RadioSelect>
</Actions>

Image

Embeds an image in the card.

lib/bot.tsx

<Image url="https://example.com/screenshot.png" alt="Screenshot" />

Divider

A visual separator between sections.

lib/bot.tsx

<CardText>Above the line</CardText>
<Divider />
<CardText>Below the line</CardText>

Full example

lib/bot.tsx

import {
  Card, CardText, Button, LinkButton, Actions,
  Section, Fields, Field, Divider, Image,
  Select, SelectOption, RadioSelect,
} from "chat";

        <SelectOption label="Admin" value="admin" />
      </Select>
