Merchant handling

Actions to be taken

Do not provide goods or services unless a later authorization is approved. Ask the cardholder to contact the issuer or use another payment method, following 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.
