API reference
External Order Fulfillment
Report approved partner sales with scoped products and stable transaction references.
Use the approved relationship
Authenticate with the partner Bearer key and the permitted sales:write or orders:write scope. Report the external order and its relevant product lines using the contract in the partner API reference. Assignments and serial/entitlement policy decide what can be fulfilled.
The /sales and /orders surfaces share the fulfillment service. A new operation returns 201; an idempotent replay or recognized duplicate returns 200. These are not two separate sales to report for the same purchase.
Reconcile outcomes
Save the returned SoundSync order/line references, allocated delivery, and safe error codes. Keep the same idempotency key for an unchanged retry. A WooCommerce mixed cart must not fulfill unrelated store items or silently approve an unmapped candidate.
External fulfillment does not automatically put the reseller transaction under SoundSync Merchant of Record coverage.
