Decline codes

Declined payments appear in payment.last_payment_error.decline_code and in the payment.failed event: generic_decline, insufficient_funds, expired_card, incorrect_cvc, incorrect_number, card_not_supported, currency_not_supported, do_not_honor, fraudulent, lost_or_stolen_card, restricted_card, authentication_failed, authentication_required, withdrawal_limit_exceeded, pin_required, shopper_canceled, issuer_unavailable, processing_error, transaction_not_permitted, amount_limit_exceeded. The message of a decline is safe to show to shoppers. Do not show more detail: issuers’ raw responses can help fraudsters.
