Merchant handling
Actions to be taken
Do not submit or fulfill the transaction again until its status has been checked. Reconcile the original request and reverse or correct duplicates according to the acquirer’s procedure.
This is conservative merchant guidance derived from the published response meaning. Current scheme, acquirer, processor, merchant advice, and transaction-specific rules take precedence.
