Communication
Send a Lark Group Message
Send a configured text message to a Lark group as an app.
Download workflow
Send a configured text message to a Lark group as an app.
Setup and use
Create a Lark app with permission to send messages and add it to the target chat. Obtain a tenant access token and chat ID. In Open Flow set the chat ID and text in Prepare the message, then bind the tenant token to a secret Variable in Send to Lark. In n8n set the chat ID and text in Input and configure Header Auth with Authorization: Bearer YOUR_TENANT_TOKEN. Tenant access tokens expire; refresh the credential before it expires.
Behavior
A manual run sends one text message as the app to the configured group. The example message is the source author’s website URL. A successful response confirms acceptance by Lark, not that every member read it. If the result is unknown, inspect the chat before retrying to avoid a duplicate.

Changes to the source
- Replace source account data with configuration and use Lark’s current IM v1 endpoint. The source fetched a tenant token but did not connect it to the send node; both formats use an explicitly configured tenant token.
- Check Lark’s response code and message ID.
