+### WebHooks
+
+Webhooks allow Lemon Squeezy to send new data to your application when certain events occur inside your store.
+You can use the sample code below as inspiration for a basic `http.HandlerFunc` which processes webhook events on your server.
+
+```go
+func WebhookHandler(_ http.ResponseWriter, req *http.Request) {
+
+	// 1. Authenticate the webhook request from Lemon Squeezy using the `X-Signature` header
+
+	// 2. Process the payload if the request is authenticated
+	eventName := req.Header.Get("X-Event-Name")
+	payload, err := io.ReadAll(req.Body)
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	switch eventName {
+	case lemonsqueezy.WebhookEventSubscriptionCreated:
+		var request lemonsqueezy.WebhookRequestSubscription
+		if err = json.Unmarshal(payload, &request); err != nil {
+			log.Fatal(err)
+		}
+		// handle subscription_created request
+	case lemonsqueezy.WebhookEventOrderCreated:
+		var request lemonsqueezy.WebhookRequestOrder
+		if err = json.Unmarshal(payload, &request); err != nil {
+			log.Fatal(err)
+		}
+		// handle order_created request
+	default:
+		log.Fatal(fmt.Sprintf("invalid event [%s] received with request [%s]", eventName, string(payload)))
+	}
+}
+```
