12.8Example: order creation

Request:

{
  "orderId": "ORD-10025",
  "customerId": "C001",
  "amount": 499.95
}

Here:

orderId

may serve both as:

business identity
+
idempotency identity

If Salesforce stores:

External_Order_ID__c = ORD-10025

and Mule uses Upsert:

retry does not create a second order

Perfect.
