Lark Messenger Management

Overview

The node "Lark Messenger" provides integration with the Lark messaging platform, specifically enabling management and interaction with messenger groups. The "Obtain Group Information" operation under the "Group" resource allows users to retrieve detailed information about a specific group (chat) in Lark Messenger by providing its unique group ID.

This node is beneficial in scenarios where automation workflows need to fetch metadata or status about a group chat, such as verifying group existence, retrieving group details for logging, or integrating group info into other systems.

Example use cases:

  • Automatically fetching group details when a new message arrives to enrich logs or trigger conditional logic.
  • Integrating group information into CRM or project management tools.
  • Monitoring group properties for compliance or auditing purposes.

Properties

Name Meaning
Authentication Method of authenticating API requests. Options: "Tenant Token" (using a tenant-level API token) or "OAuth2" (using OAuth 2.0 authentication flow).
Chat Id The unique identifier of the group (chat) whose information is to be obtained. This is required.
Options Additional optional settings:
• Use Custom Body: Whether to send a custom request body instead of the default one (boolean).

Output

The output JSON contains the detailed information about the specified group chat retrieved from the Lark Messenger API. This typically includes fields such as group name, description, member list, creation time, and other metadata related to the group.

If the node supports binary data output (not indicated here), it would represent any files or media associated with the group, but this operation primarily returns structured JSON data describing the group.

Dependencies

  • Requires an active connection to the Lark Open APIs endpoint (https://open.larksuite.com/open-apis).
  • Requires authentication via either:
    • A tenant-level API token credential.
    • An OAuth2 credential configured for Lark.
  • Proper configuration of credentials within n8n is necessary to authorize API calls.

Troubleshooting

  • Common issues:

    • Invalid or missing Chat Id: The node requires a valid group ID; ensure the ID is correct and accessible.
    • Authentication errors: Ensure that the provided API token or OAuth2 credentials are valid and have sufficient permissions.
    • Network or API endpoint errors: Verify network connectivity and that the Lark API service is operational.

  • Error messages:

    • Unauthorized or 401 errors indicate invalid or expired credentials; reauthenticate or update credentials.
    • 404 Not Found may indicate the group ID does not exist or the authenticated user lacks access.
    • 400 Bad Request could result from malformed input or incorrect parameters; verify the Chat Id format.
