+# Google Chat Integration
+
+## Overview
+
+This documentation covers setting up OpenClaw's Google Chat integration via the Chat API with webhook support for direct messages and spaces.
+
+## Setup Steps
+
+### 1. Google Cloud Project
+
+Enable the Chat API and create service account credentials, downloading a JSON key file for authentication.
+
+### 2. Chat App Configuration
+
+Register the app in Google Cloud Console with basic info (name, avatar, description), enable interactive features, and configure an HTTP endpoint.
+
+### 3. Webhook Configuration
+
+Set the endpoint to your gateway's public URL with "/googlechat" path and establish visibility restrictions to specific users.
+
+### 4. App Status Activation
+
+After saving, refresh and change app status to "Live" for user availability.
+
+### 5. OpenClaw Configuration
+
+Configure the service account file path and webhook audience settings via environment variables or config files.
+
+### 6. Adding to Chat
+
+Users can find the private app by searching its name in Google Chat and start conversations.
+
+## Security Architecture
+
+Only expose the `/googlechat` path to the internet. Three recommended approaches:
+
+### Tailscale Funnel
+
+Combines private dashboard access via Serve with public webhook exposure via Funnel.
+
+### Reverse Proxy (Caddy)
+
+Routes only the specific webhook path while blocking other requests.
+
+### Cloudflare Tunnel
+
+Configures ingress rules limiting access to the webhook endpoint.
+
+## Message Routing
+
+Messages are processed through space-based routing using session keys that differentiate between direct messages and group spaces.
+
+- **Direct messages** employ pairing by default requiring approval codes
+- **Group spaces** require @-mentions unless configured otherwise
+
+## Configuration Options
+
+The system supports:
+
+- Service account authentication
+- Optional bot user identification
+- Group allowlisting
+- Reaction handling
+- Typing indicators
+- Media attachments up to a configurable size limit
