This is a dummy endpoint that demonstrates the webhook payload structure that will be sent to webhook subscribers when an order.created event occurs.
The actual webhooks will be sent asynchronously to the URLs specified in the webhook subscriptions that are subscribed to the order.created event type.
The webhook payload includes:
id: ID of the webhook message
event: The event type (order.created)
timestamp: When the event occurred
subscription_id: ID of the webhook subscription
message: The order data in the same format as the GET /orders/{id} endpoint
