Card Error Codes



A card payment can be rejected at the time of creation, even before the money is debited. However, the issuing banks do not necessarily provide the card networks (VISA, Mastercard etc) with the precise reason why they rejected a payment. As such, the payment error displayed by the SlimPay API might be inaccurate. Please bear in mind that SlimPay acts merely as a gateway with regards to these error codes.

However, the following codes (included in the API’s payment-issues response) offer some indication about why a card payment was rejected:

C01 This account does not exist
C02 Contact your bank for authorisation
C03 Operation cancellation unauthorised
C04 Card expired
C05 Card lost
C06 Card stolen

C09 Duplicated transaction
C10 The usage frequency is exceeded
C11 There is an opposition on the account
C12 The bank is unknown
C13 Invalid card number
