Set a URL to receive webhook notifications for events in your Yativo account. Yativo sends a POST request to your endpoint whenever a matching event occurs and signs every request with an X-Yativo-Signature header for verification. 
POST /business/webhook
Requires an Idempotency-Key header. Update an existing webhook URL with PUT /business/webhook.

​
Request Body

url

Signature Verification

Every webhook delivery includes an X-Yativo-Signature header — an HMAC SHA256 hex digest of the raw request body signed with your webhook secret. Algorithm: 
X-Yativo-Signature = HMAC-SHA256(webhookSecret, rawRequestBody) → hex
Always verify the signature before processing any event. Use constant-time comparison to prevent timing attacks — never a plain string equality check.
Compute the HMAC over the raw request body bytes — not a re-serialized version of parsed JSON. Parsing and re-stringifying can change whitespace or key ordering, causing signature mismatches.

Verification examples

const crypto = require('crypto');

app.post('/webhooks/yativo', express.raw({ type: 'application/json' }), (req, res) => {
  const secret = process.env.YATIVO_WEBHOOK_SECRET;
  const receivedSignature = req.headers['x-yativo-signature'];

  const expectedSignature = crypto
    .createHmac('sha256', secret)
    .update(req.body)
    .digest('hex');

  if (!crypto.timingSafeEqual(
    Buffer.from(expectedSignature),
    Buffer.from(receivedSignature)
  )) {
    return res.status(401).send('Invalid signature');
  }

  const event = JSON.parse(req.body);
  // safe to process
  res.status(200).send('OK');
});
