You’re right Etsy doesn’t currently provide a real-time order webhook or push notification through the public API. The most common solution is to poll the Orders API periodically (for example, every few minutes) and compare order IDs or timestamps to detect new sales. Some developers also use third-party integrations or middleware services that automate this polling and send notifications when new orders appear. While not ideal, this approach is the most reliable until Etsy offers an official event or webhook system.
