OpenClaw & Feishu Integration

Summary

Successfully integrated OpenClaw agent framework with Feishu (Lark) messaging platform, enabling AI agents to receive and respond to messages through Feishu channels. This establishes a new communication channel alongside existing web chat interfaces.

Key Achievements

Component	Status	Description
Feishu Channel Plugin	✅ Completed	OpenClaw now supports Feishu as a messaging channel
Message Routing	✅ Working	Messages from Feishu properly routed to agent sessions
Bi-directional Communication	✅ Verified	Agent can send replies back to Feishu users
Webhook Integration	✅ Configured	Feishu bot webhooks integrated with OpenClaw gateway

Technical Details

Architecture Flow:

Feishu User → Feishu Bot Webhook → OpenClaw Gateway → Agent Session → AI Response → Feishu User

Configuration:

• Feishu bot configured with event subscriptions
• OpenClaw gateway configured with Feishu channel plugin
• Message parsing and formatting adapted for Feishu platform

Benefits

• Multi-platform Support: Users can now interact with agents via Feishu or web chat
• Mobile Access: Feishu mobile app enables on-the-go agent communication
• Enterprise Integration: Seamless integration with Feishu workspace

Agent Communication Protocol

Summary

Established a secure, standardized bidirectional communication protocol between Benben and Hygge AI agents. This enables real-time collaboration and task delegation between agents via HTTP API with authentication.
