Chat SDK adds WhatsApp adapter support

Chat SDK now supports WhatsApp, extending its single-codebase approach to Slack, Discord, GitHub, Teams, and Telegram with the new WhatsApp adapter.

Teams can build bots that support messages, reactions, auto-chunking, and read receipts. The adapter handles multi-media downloads (e.g., images, voice messages, stickers) and supports location sharing with Google Maps URLs.

Try the WhatsApp adapter today:

1
import { Chat } from "chat";
2
import { createWhatsAppAdapter } from "@chat-adapter/whatsapp";
3

4
const bot = new Chat({
5
  userName: "mybot",
6
  adapters: {
7
    whatsapp: createWhatsAppAdapter(),
8
  },
9
});
10

11
bot.onNewMention(async (thread, message) => {
12
  await thread.post(`You said: ${message.text}`);
13
});

The adapter does not support message history, editing, or deletion. Cards render as interactive reply buttons with up to three options, and fall back to formatted text. Additionally, WhatsApp enforces a 24-hour messaging window, so bots can only respond within that period.

Read the documentation to get started, browse the directory, or build your own adapter.
