Price and order intent
Approve KRW display, rounding, fees, tax presentation, recurring terms, cancellation information, Korean wording, accessible choices, and the exact moment an order is created.
Transaction status / provider unconfirmed
Test every KRW state before calling the checkout ready.
Local methods, platforms, and authentication routes require current provider and client confirmation. Faith Forge Labs can build the approved flow and its evidence without claiming automatic access to any South Korean payment service.
Provider and platform ownership
Confirm merchant entity, contracts, settlement, supported methods, app-store or platform constraints, credentials, authentication, callbacks, prohibited uses, and vendor support.
Uncertain and failed state
Exercise decline, timeout, abandoned authentication, duplicate notification, delayed result, partial fulfillment, provider outage, and the safe customer response while status is unknown.
Refund and dispute
Assign request intake, transaction verification, authorization, provider action, evidence, communication, dispute handling, status tracking, and final record closure.
Reconciliation and invoices
Join order IDs, provider references, settlement reports, exceptions, invoices, refunds, and retained records. The appropriate business, accounting, or tax owner approves treatment.
Controlled production proof
Use sandbox and limited live cases, accessible state checks, webhook logs, reconciliation evidence, alerts, rollback criteria, and a named release authority.
Use the Bank of Korea and National Tax Service as official research feeds. Providers and qualified accounting, tax, legal, or regulatory owners must confirm the actual arrangement.
Transaction case
Submit one successful purchase and one unknown outcome.
Those two paths reveal order-state, support, reconciliation, and recovery decisions that a happy-path checkout demonstration can hide.
