What happens when credit card payment is not successful

The way of notifying is dependent on transaction type case:

• When charging customer via register sale method, the customer will receive reason of payment rejection at our transaction panel. After that, he will be able to use another card or redirected to merchant error page defined at merchant settings or sent with transaction parameters. Merchant system should allow the customer to try again by generating new transaction or redirecting to the same transaction link again.
• When charging customer via secure sale method
  • 3DS case:
    The customer will receive reason of payment rejection at our transaction panel. After that, he will be redirected to merchant error page defined at merchant settings or sent with transaction parameters. Merchant system should allow the customer to try again by generating new transaction or redirecting to 3DS link again.
  • No 3DS case: our API will return sale response immediately with an error code, which can be recognized at this table.
    
    
• When charging saved card via presale and sale methods (recurrent payments) our API will return sale response immediately with an error code, which can be recognised at this table.
