Response Codes - Payment Processing

If you’re a partner, for example with a gateway that you want to integrate with our acquiring platform, the following codes can help you to understand why and how a payment has failed. Each response code has one of the following prefixes: 

V is a validation error (for example, invalid card number) 
D is a declined transaction 
R is a referral (to be treated as a declined transaction) 
B is a blocked transaction 
C is a cancelled transaction (for example, a user selected Cancel on a payment page) 
S is a system error 

The prefix is followed by three digits, for example x01. The first digit, for example the x, is for internal use only. The next two digits, for example the 01, provide more details about the response. The following list presents the code and the message for each response.
