Verifying Webhook Signatures (HMAC-SHA256)
Every request contains an X-Sancharya-Signature header. Calculate the HMAC of the raw request body with your webhook signing secret using SHA-256 and compare in constant time:
// Node.js / Express verification example
const crypto = require('crypto');
function verifySancharyaWebhook(rawBody, signatureHeader, secret) {
const hmac = crypto.createHmac('sha256', secret);
const digest = 'sha256=' + hmac.update(rawBody).digest('hex');
return crypto.timingSafeEqual(Buffer.from(signatureHeader), Buffer.from(digest));
}
