Merchant handling

Actions to be taken

Do not assume that the transaction is approved and do not submit a duplicate immediately. Check the transaction status or wait for the processor’s final response before fulfillment.

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