Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Retrieve the supplier's Order Status WSDL (OS 1.0.0 is legacy; OS 2.0.0 is the current recommended endpoint)
Call getOrderStatusDetails with the distributor's PO number and supplier-issued credentials
Parse the returned OrderStatus and OrderStatusLine elements, including ship-date and tracking references
Map PromoStandards status codes to your own internal order-state machine, since supported status subsets vary by supplier
Known gotchas
OS is the most widely adopted PromoStandards service, but OS 1.0.0 and OS 2.0.0 return different element structures — confirm which version a given supplier actually runs
Suppliers often only populate status for orders placed through their own official intake channel, not orders relayed through an intermediary
A single PO/order number query can return multiple OrderStatus records (partial fulfillment); code for arrays, not a single object
