How do I send my new orders to another app using a webhook?

Go to Plugins → Webhooks (marked Beta).

1. Under Add a webhook, enter the full web address your app gave you.
2. Click the events you want, such as order.created, order.shipped or customer.registered. Pick at least one.
3. Click Create webhook.
4. A Signing secret appears once. Copy it now and give it to your app, so it can check each message really came from your store.

The new webhook appears under Subscriptions as active. Each time a chosen event happens, your store posts the details to that address. Results show under Recent deliveries.
