Webhooks

TradeClaw can push signal and price events to any URL — signals fire on the 5-minute cron, price events stream within seconds for crypto and ≤60s for FX/metals/stocks. Each delivery is signed with HMAC-SHA256 so your receiver can verify the payload came from your instance — not a third party.

Setup via the UI

Navigate to Settings → Webhooks in the dashboard. Click Add Webhook, enter your endpoint URL, optionally provide a secret, and save. You can test delivery immediately from the same panel.

Enter URL

HTTPS endpoint that accepts POST requests

Set Secret

Optional. Used to sign and verify payloads

Test Delivery

Send a sample payload to confirm connectivity

Or create via API

curl -X POST https://your-instance.com/api/webhooks \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://your-app.com/webhooks/tradeclaw",
    "name": "My Signal Receiver",
    "secret": "whsec_your_secret_here"
  }'

# Response
{
  "id": "wh_abc123",
  "url": "https://your-app.com/webhooks/tradeclaw",
  "name": "My Signal Receiver",
  "enabled": true,
  "createdAt": "2026-03-27T12:00:00Z"
}

HMAC-SHA256 Signing

Every delivery includes an X-TradeClaw-Signature header. The value is the HMAC-SHA256 of the raw request body using your webhook secret as the key, encoded as a hex string prefixed with sha256=.

Header: X-TradeClaw-Signature

Value: sha256=<hex(HMAC-SHA256(secret, rawBody))>

Also includes: X-TradeClaw-Delivery (unique delivery ID)

Also includes: X-TradeClaw-Event (event type string)

Important: Always verify the signature before processing the payload. Use a constant-time comparison to prevent timing attacks.

Node.js — signature verification

const crypto = require('crypto');

function verifySignature(secret, rawBody, signatureHeader) {
  const expected = 'sha256=' + crypto
    .createHmac('sha256', secret)
    .update(rawBody, 'utf8')
    .digest('hex');

  // Use timingSafeEqual to prevent timing attacks
  return crypto.timingSafeEqual(
    Buffer.from(expected, 'utf8'),
    Buffer.from(signatureHeader, 'utf8')
  );
}

// Express receiver
app.post('/webhooks/tradeclaw', express.raw({ type: '*/*' }), (req, res) => {
  const sig = req.headers['x-tradeclaw-signature'];
  if (!verifySignature(process.env.WEBHOOK_SECRET, req.body, sig)) {
    return res.status(401).send('Invalid signature');
  }

  const event = JSON.parse(req.body.toString());
  console.log('Event type:', event.type);
  res.sendStatus(200);
});

Payload Schema

All webhook payloads share a common envelope. The data field contains the event-specific object.

typescript

interface WebhookPayload {
  id: string;          // Unique delivery ID (same as X-TradeClaw-Delivery)
  type: WebhookEventType;
  createdAt: string;   // ISO 8601
  data: SignalEvent | PriceEvent | AlertEvent;
}

type WebhookEventType =
  | 'signal.created'
  | 'signal.updated'
  | 'price.alert'
  | 'tp.hit'
  | 'sl.hit';

// signal.created example
{
  "id": "del_xyz789",
  "type": "signal.created",
  "createdAt": "2026-03-27T14:30:00Z",
  "data": {
    "id": "sig_abc123",
    "symbol": "XAUUSD",
    "timeframe": "H1",
    "direction": "BUY",
    "confidence": 87,
    "entryPrice": 2345.50,
    "tp1": 2360.00, "tp2": 2374.50, "tp3": 2389.00,
    "sl": 2331.00
  }
}

Discord & Slack Auto-Formatting

TradeClaw detects Discord and Slack webhook URLs automatically and sends rich formatted messages instead of raw JSON — no middleware required.

Discord

Sends an embed with colored sidebar (green for BUY, red for SELL), symbol, direction, confidence, entry, TP levels, and SL. URLs matching discord.com/api/webhooks are auto-detected.

Slack

Sends a Block Kit message with sections and context blocks. URLs matching hooks.slack.com are auto-detected and formatted accordingly.

Retry Logic

If your endpoint returns a non-2xx status code or times out, TradeClaw retries with exponential backoff. A delivery is considered failed after 3 attempts.

Attempt	Delay	Timeout
1st (initial)	Immediate	5s
2nd	5 seconds	5s
3rd (final)	25 seconds	5s

View delivery history and retry status at GET /api/webhooks/[id]/deliveries. Trigger a manual redeliver with POST /api/webhooks/deliver.

Rate Limiting

Webhook deliveries are rate-limited to one per 5 seconds per endpoint URL. High-frequency price events are batched before dispatch to avoid overwhelming receivers. Signal events are never batched — each signal triggers an individual delivery.

Max delivery rate: 1 per 5 seconds per URL

Signal events: Immediate, never batched

Price events: Batched into 5s windows

Max webhooks per instance: 20

Python Flask Receiver

webhook_receiver.py

import hashlib
import hmac
import os
from flask import Flask, request, abort

app = Flask(__name__)
WEBHOOK_SECRET = os.environ['WEBHOOK_SECRET']

def verify_signature(secret: str, body: bytes, signature: str) -> bool:
    expected = 'sha256=' + hmac.new(
        secret.encode(), body, hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, signature)

@app.route('/webhooks/tradeclaw', methods=['POST'])
def receive_webhook():
    sig = request.headers.get('X-TradeClaw-Signature', '')
    if not verify_signature(WEBHOOK_SECRET, request.data, sig):
        abort(401)

    event = request.get_json()
    event_type = event.get('type')

    if event_type == 'signal.created':
        data = event['data']
        print(f"New signal: {data['symbol']} {data['direction']} @ {data['confidence']}%")
    elif event_type == 'price.alert':
        print(f"Alert triggered: {event['data']}")

    return '', 200

if __name__ == '__main__':
    app.run(port=3001)
