description: HMAC-SHA256 signature of the request body using your webhook secret. Verify this signature to ensure the webhook is from Crown.
x-webhook-security:
note: All webhook requests include an X-Crown-Signature header containing an HMAC-SHA256 signature of the request body. Use your webhook secret (provided when registering the webhook) to verify the signature and ensure the request is authentic.
algorithm: HMAC-SHA256
header: X-Crown-Signature
verification-steps:
- 1. Extract the X-Crown-Signature header from the request
- 2. Compute HMAC-SHA256 of the raw request body using your webhook secret
- 3. Compare the computed signature with the header value
- 4. Only process the webhook if signatures match
example-code:
node-js: "const crypto = require('crypto');\nconst signature = crypto.createHmac('sha256', webhookSecret)\n .update(JSON.stringify(requestBody))\n .digest('hex');\nconst isValid = signature === req.headers['x-crown-signature'];"
python: "import hmac\nimport hashlib\nimport json\n\nsignature = hmac.new(\n webhook_secret.encode('utf-8'),\n json.dumps(request_body).encode('utf-8'),\n hashlib.sha256\n).hexdigest()\nis_valid = signature == request.headers['x-crown-signature']"
