Use these options to check that username and passwords specified by the merchant match those used with each transaction. If there is any discrepancy, the transaction authorization is declined.
This option can only be used when communicating with Bambora Payments API. It is required for all pre-auth completions, adjustments,void, and return transactions that are not performed using the Web POS terminal or Transaction Report. It can also be used with or instead of, the Validate Referring Host option.
Declining When CVD/AVS Mismatch
Bambora users have flexible risk management controls. You have the option to reverse a transaction when CVD and/or AVS fields are returned as a mismatch. This optional feature is configured in the Online Member Area under: administration> account settings> order settings.
After these options are enabled, an approved transaction containing a CVD and/or AVS mismatch is reversed as a VOID. A decline is then returned to the client:
- CVD Mismatch or CVD Issuer Unable to Process Request): response message ID – 821
- AVS mismatch: response message ID – 822
- If a browser disconnect occurs, the transaction is treated as an address mismatch and is VOIDED
