+# OpenClaw Webhooks
+
+## When to Use This Skill
+
+- Receiving webhook calls from an OpenClaw Gateway
+- Verifying `Authorization: Bearer <token>` or `x-openclaw-token` headers
+- Handling `/hooks/agent` and `/hooks/wake` event payloads
+- Building external services that react to OpenClaw agent activity
+
+## Essential Code (USE THIS)
+
+### OpenClaw Token Verification (JavaScript)
+
+```javascript
+const crypto = require('crypto');
+
+function verifyOpenClawWebhook(authHeader, xTokenHeader, secret) {
+  // OpenClaw sends the token in one of two headers:
+  //   Authorization: Bearer <token>
+  //   x-openclaw-token: <token>
+  const token = extractToken(authHeader, xTokenHeader);
+  if (!token || !secret) return false;
+
+  try {
+    return crypto.timingSafeEqual(
+      Buffer.from(token),
+      Buffer.from(secret)
+    );
+  } catch {
+    return false;
+  }
+}
+
+function extractToken(authHeader, xTokenHeader) {
+  if (xTokenHeader) return xTokenHeader;
+  if (authHeader && authHeader.startsWith('Bearer '))
+    return authHeader.slice(7);
+  return null;
+}
+```
+
+### Express Webhook Handler
+
+```javascript
+const express = require('express');
+const app = express();
+
+app.post('/webhooks/openclaw',
+  express.json(),
+  (req, res) => {
+    const authHeader = req.headers['authorization'];
+    const xToken = req.headers['x-openclaw-token'];
+
+    if (!verifyOpenClawWebhook(authHeader, xToken, process.env.OPENCLAW_HOOK_TOKEN)) {
+      console.error('OpenClaw token verification failed');
+      return res.status(401).send('Invalid token');
+    }
+
+    const { message, name, wakeMode, agentId, sessionKey } = req.body;
+
+    console.log(`[${name || 'OpenClaw'}] ${message}`);
+
+    // Respond quickly - OpenClaw expects 200 or 202
+    res.status(200).json({ received: true });
+  }
+);
+```
+
+### Python Token Verification (FastAPI)
+
+```python
+import hmac
+
+def verify_openclaw_webhook(auth_header: str | None, x_token: str | None, secret: str) -> bool:
+    token = x_token
+    if not token and auth_header and auth_header.startswith("Bearer "):
+        token = auth_header[7:]
+    if not token or not secret:
+        return False
+    return hmac.compare_digest(token, secret)
+```
+

+> - [examples/express/](examples/express/) - Full Express implementation
+> - [examples/nextjs/](examples/nextjs/) - Next.js App Router implementation
+> - [examples/fastapi/](examples/fastapi/) - Python FastAPI implementation
+
+## Webhook Endpoints
+
+OpenClaw Gateway exposes two webhook endpoints. Your external service receives POSTs from the Gateway (or a relay like Hookdeck) on a URL you choose.
+
+| Endpoint | Purpose | Response |
+|----------|---------|----------|
+| `POST /hooks/agent` | Trigger an isolated agent turn | `202 Accepted` |
+| `POST /hooks/wake` | Enqueue a system event | `200 OK` |
+
+## Agent Hook Payload
+
+```json
+{
+  "message": "Summarize inbox",
+  "name": "Email",
+  "agentId": "hooks",
+  "sessionKey": "hook:email:msg-123",
+  "wakeMode": "now",
+  "deliver": true,
+  "channel": "last",
+  "to": "+15551234567",
+  "model": "openai/gpt-5.2-mini",
+  "thinking": "low",
+  "timeoutSeconds": 120
+}
+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `message` | Yes | Prompt or message for the agent |
+| `name` | No | Human-readable hook name (e.g. "GitHub", "Email") |
+| `agentId` | No | Route to a specific agent; falls back to default |
+| `sessionKey` | No | Session key (disabled by default) |
+| `wakeMode` | No | `now` (default) or `next-heartbeat` |
+| `deliver` | No | Send agent response to messaging channel (default `true`) |
+| `channel` | No | `last`, `whatsapp`, `telegram`, `discord`, `slack`, `signal`, `msteams` |
+| `to` | No | Recipient identifier for the channel |
+| `model` | No | Model override for this run |
+| `thinking` | No | Thinking level: `low`, `medium`, `high` |
+| `timeoutSeconds` | No | Max duration for the agent run |
+
+## Wake Hook Payload
+
+```json
+{
+  "text": "New email received",
+  "mode": "now"
+}
+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `text` | Yes | Description of the event |
+| `mode` | No | `now` (default) or `next-heartbeat` |
+
+## Authentication Headers
+
+OpenClaw supports two header styles. Pick one:
+
+| Header | Format |
+|--------|--------|
+| `Authorization` | `Bearer <token>` (recommended) |
+| `x-openclaw-token` | `<token>` |
+
+Query-string tokens (`?token=...`) are rejected with `400`.
+
+## Response Codes
+
+| Code | Meaning |
+|------|---------|
+| `200` | Wake event accepted |
+| `202` | Agent hook accepted (async run started) |
+| `400` | Invalid payload or query-string token |
+| `401` | Authentication failed |
+| `413` | Payload too large |
+| `429` | Rate-limited (check `Retry-After` header) |
+
+## Environment Variables
+
+```bash
+OPENCLAW_HOOK_TOKEN=your_shared_secret   # Must match hooks.token in Gateway config
+```
+
+## Local Development
+
+```bash
+# Install Hookdeck CLI for local webhook testing
+brew install hookdeck/hookdeck/hookdeck
+
+# Start tunnel (no account needed)
+hookdeck listen 3000 --path /webhooks/openclaw
+```

+## Recommended: webhook-handler-patterns
+
+We recommend installing the [webhook-handler-patterns](https://github.com/hookdeck/webhook-skills/tree/main/skills/webhook-handler-patterns) skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):
+
+- [Handler sequence](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/handler-sequence.md) - Verify first, parse second, handle idempotently third
+- [Idempotency](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/idempotency.md) - Prevent duplicate processing
+- [Error handling](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/error-handling.md) - Return codes, logging, dead letter queues

+# OpenClaw Webhooks - Express Example
+
+Minimal example of receiving OpenClaw Gateway webhooks with token verification.
+
+## Prerequisites
+
+- Node.js 18+
+- An OpenClaw Gateway with webhooks enabled
+
+## Setup
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Copy environment variables:
+   ```bash
+   cp .env.example .env
+   ```
+
+3. Add your OpenClaw hook token to `.env`
+
+## Run
+
+```bash
+npm start
+```
+
+Server runs on http://localhost:3000
+
+## Test
+
+### Using Hookdeck CLI
+
+```bash
+# Install Hookdeck CLI
+brew install hookdeck/hookdeck/hookdeck
+
+# Forward webhooks to localhost
+hookdeck listen 3000 --path /webhooks/openclaw
+```
+
+Configure the Hookdeck URL in your external service or use it directly with `curl`.
+
+### Manual Test
+
+```bash
+curl -X POST http://localhost:3000/webhooks/openclaw \
+  -H 'Authorization: Bearer your_hook_token_here' \
+  -H 'Content-Type: application/json' \
+  -d '{"message": "Hello from test", "name": "Test"}'
+```
+
+## Endpoints
+
+- `POST /webhooks/openclaw` - Receives agent hook events
+- `POST /webhooks/openclaw/wake` - Receives wake events
+- `GET /health` - Health check
