[Finix Docs, Fraud and Risk]: Declines come from the card issuer or from risk checks, so read the decline reason on the transfer object rather than retrying blindly. Typical fixes are per-case: expired or lost cards need a new payment instrument, insufficient-funds declines are retryable later, and risk-flagged transactions need the cardholder details re-verified. Disable payment instruments that are no longer used so stale instruments do not keep generating declines.

Context: Finix transfers get declined and the dashboard shows a decline but no clear reason. Finix documents why payments fail and how to handle declines.
