I am using Postman to create Order Requests to my sanbox test account. In the developer dashboard, I can see customers I have created, and transactions that have been processed. However, I cannot see the orders that I created with the CreateOrder request.
If you retrieve an order (BatchRetrieveOrders) then it should have the version of the order in the request, or if you just do a general search (SearchOrders), then you’ll also see it.
As far as I know, the version should only update when a successful change to the order was made. If you’ve pushed it to the dashboard/POS, and interact with it via the dashboard/POS, then that would count as a successful change to the order and should update the version as well, just to be clear.
