Introduction to Level II and Level III Processing : CyberSource Level II and Level III Data Processing

CyberSource Level II and Level III Data Processing
CyberSource does not store the Level II and Level III data. Instead, it functions as a pass-through service for the data. If you request multiple partial captures or credits for an order, you must include the Level II and Level III data in each request.
CyberSource enforces only a minimal level of field validation to avoid interfering with the business policies between you and the companies that purchase your goods and services.
 
CyberSource temporarily disables your account’s Level III processing capability and contacts you if your Level III transactions produce batching errors when the information is sent to your processor. When this happens, your request is not rejected, but the reply message from CyberSource includes a field indicating that the Level III information was ignored and was not sent to the processor.
For captures, the reply field is ccCaptureReply_purchasingLevel3Enabled.
For credits, the reply field is ccCreditReply_purchasingLevel3Enabled.
Y: the Level III data was included in the request to the processor.
N: the Level III data was not included in the request to the processor.
