You can now pause a Workflow run on a Chat SDK card and resume it when someone clicks a button. The same flow works for form submissions. Buttons and modals accept a new callbackUrl prop, and the event payload is sent to that endpoint.
To build a card like this, create a workflow webhook and pass its URL to each button's callbackUrl prop inside your <Card> component:
import { createWebhook } from "workflow";import { Card, CardText, Actions, Button } from "chat";export async function statusReport( thread, content: { title: string; message: string },) {
"use workflow";
using hook = createWebhook<{ action: "approve" | "approve-and-send" | "deny" }>();
await thread.post( <Card title="Status Report Communications"> <CardText>Title: {content.title}</CardText> <CardText>Message: {content.message}</CardText> <Actions> <Button callbackUrl={hook.url} id="approve" style="primary"> Approve </Button> <Button callbackUrl={hook.url} id="approve-and-send" style="primary"> Approve & Send </Button> <Button callbackUrl={hook.url} id="deny" style="danger"> Cancel </Button> </Actions> </Card> );
const { action } = await hook; if (action === "approve" || action === "approve-and-send") { await sendReport(content); }
}Create an approval card to approve or deny a deployment
For the <Modal> component, the form data is in the payload. callbackUrl works for buttons on most platforms with an official adapter, and for modals on Slack and Teams.
