Retry Logic

Retry logic is the set of rules, timing parameters, and conditions that govern when and how a declined payment transaction is reattempted. It is the operational mechanism through which merchants recover revenue from Soft Declines, transactions that failed for temporary or potentially recoverable reasons rather than definitive refusals.

Effective retry logic is calibrated to decline type, not applied uniformly. A Soft Decline for insufficient funds is best retried after a delay long enough for the cardholder's account to be replenished, often 24 to 72 hours, or timed around typical payroll cycles. An authentication-required decline should trigger an immediate re-submission through a 3DS2 flow rather than a time-delayed retry. A "do not honor" response from an established customer with no prior issues may succeed on a retry within hours. A lost or stolen card (Hard Decline) should never be retried.

Card network compliance is a hard constraint on retry logic. Both Visa and Mastercard publish retry guidelines specifying maximum retry counts and minimum intervals for specific decline reason codes. Retrying transactions more frequently than permitted, "hammering" declined cards with repeated authorization attempts, generates fees from card networks, risks issuer blocks, and may be flagged as a network rules violation. Well-built retry logic respects these limits automatically, applying network-compliant intervals and maximum attempt counts for each decline code category.

For subscription businesses, retry logic is formalized through Dunning Management, a systematic workflow combining smart retry scheduling with cardholder notification campaigns. The goal is to maximize the share of failed subscription payments recovered automatically (through successful retries) while using notification triggers to prompt manual card updates for cases that automation cannot resolve.
