# Chat SDK adds Lark and Feishu support

By Steven Van · 2026-05-31

The adapter runs over Lark's WebSocket transport, so bots need no public webhook endpoint to post or edit messages.

A new vendor-official adapter adds Lark and Feishu support to [Vercel](<https://creatorstoolbox.com/tools/vercel>)'s Chat SDK.

- Bots can post, edit, and delete messages, and react with emojis across both platforms.

- Replies can stream through Lark's native cardkit typewriter API.

- Bots can send interactive cards and respond to @-mentions.

The adapter connects over Lark's WebSocket transport, so bots run from any long-running Node process without exposing an HTTP webhook endpoint. [Read the announcement](<https://vercel.com/changelog/chat-sdk-adds-lark-feishu-support>) for links to the Lark and Feishu documentation.
