Chat SDK now supports scheduled Slack messages

Chat SDK now supports scheduled messages on Slack, allowing you to deliver a message at a future time.

Use thread.schedule() and pass your message and a postAt date, like:

1
const scheduled = await thread.schedule("Reminder: standup in 5 minutes!", {
2
    postAt: new Date("2026-03-09T08:55:00Z"),
3
});
4

5
// Cancel before delivery
6
await scheduled.cancel();
