This API is used to retrieve the Card verification value (CVV) data. The Credit+ Issuing system receives, validates and processes the request. If the request is successful, the cardholder will receive the CVV data in response. If the request fails, the system returns the corresponding error code.
NOTE:
Customization1. The API, if sent with cardNumberAlias (CNA), will internally fetch the corresponding associated device for further processing only if DEVICE _STATUS_CODE = NORMAL (0) OR (DEVICE_STATUS_CODE = UPGRADE (9) AND UPGRADE_STATUS = 1).
2. Either deviceNumber or cardNumberAlias parameter’s value must be provided to process the request. However, if both are received in request then the system will not validate if the cardNumberAliasislinked to that particular device. The system processesthe request based on the device number itself.
