Merchant handling
Actions to be taken
Do not complete the transaction. Ask for corrected payment details or another payment method, and submit a new authorization only when the cause has been resolved and the acquirer’s rules allow it.
This is conservative merchant guidance derived from the published response meaning. Current scheme, acquirer, processor, merchant advice, and transaction-specific rules take precedence.
