+## Webhook Signature Verification
+
+The SDK provides utility methods that allow you to verify webhook signatures and ensure that all 
+webhook events originate from Square. The `Webhooks.verifySignature` method will verify the signature.
+
+```ts
+import { WebhooksHelper } from "square";
+
+const isValid = WebhooksHelper.verifySignature({
+  requestBody,
+  signatureHeader: request.headers['x-square-hmacsha256-signature'],
+  signatureKey: "YOUR_SIGNATURE_KEY",
+  notificationUrl: "https://example.com/webhook", // The URL where event notifications are sent.
+});
