Merchant handling

Actions to be taken

Handle this as an administrative-response result and follow the requesting system’s workflow. Do not interpret it as approval for goods or services.

This is conservative merchant guidance derived from the published response meaning. Current scheme, acquirer, processor, merchant advice, and transaction-specific rules take precedence.
