What does an authorization response code represent?

An authorization response code represents a generated code based on issuer instructions. This code is crucial in payment processing as it indicates the outcome of a transaction authorization request. When a merchant submits a transaction for approval, the payment processor sends the request to the card issuer, which then reviews it according to its internal guidelines, risk assessment protocols, and account status before generating a response code.

The response code provides specific information about whether the transaction was approved or declined, and if declined, it may offer insights on the reason for the denial (e.g., insufficient funds, account not found, and so forth). This feedback is essential for both merchants and customers, as it informs them of the transaction status and any actions that may need to be taken.

The other options do not accurately define what an authorization response code is. A chargeback procedure refers to a formal dispute process initiated by the cardholder after a transaction, a transaction completion notification signifies the finalization of a payment process, and a merchant discount percentage pertains to fees that are deducted from a transaction total, which is distinct from the purpose of an authorization response code.
