Webhooks

Receive real-time payment notifications.

Configure a webhook URL in your dashboard settings. We'll send POST requests with payment updates signed using HMAC-SHA512.

Verification

verify-webhook.ts

import crypto from "crypto";

function verifyWebhook(body: string, signature: string, secret: string) {
  const hmac = crypto
    .createHmac("sha512", secret)
    .update(body)
    .digest("hex");

  return crypto.timingSafeEqual(
    Buffer.from(hmac, "hex"),
    Buffer.from(signature, "hex")
  );
}
