Descriptive Error Codes for Smarter Decline Responses

Typically, merchants will provide a relatively generic message such as Card declined or please try again or contact your bank for more information in order to avoid giving a potential fraudster too much information.

The merchant should log the actual error code and description in their system in the event they need to provide it if the shopper calls.

Some merchants may also want to handle certain error codes differently than the processor handles them. For example, a merchant may decide to decline based on a partial AVS (address) mismatch where a processor has authorized the transaction. In this case, the merchant should send a Refund request immediately to BlueSnap which will in turn cancel the authorization.

See the Documentation to learn more about error handling.
