How can I configure custom fraud validation rules in CyberSource?

If you're facing transaction issues due to fraud validation (e.g. CVV mismatch, AVS mismatch), these settings can be reviewed and configured in your CyberSource Business Center.

Steps to Configure Custom Fraud Rules:

1. Log in to your CyberSource account at: https://businesscentertest.cybersource.com/ebc2
2. Navigate to Fraud Management in the left-hand menu.
3. Go to Rule Configuration.
4. In the Standard Rules panel, you'll see predefined rules like:
   • AVS Mismatch
   • CVV Mismatch
   • Invalid Address
   • Billing-Shipping Mismatch
   • Billing-IP Country Mismatch
5. Each rule can be set to one of the following:
   • Monitor
   • Reject
   • Review
6. You can customize these rules based on your business needs. For example:
   • Set "CVV Not Verifiable" to Reject to block transactions without valid CVV.
   • Set "AVS Partial Match" to Disabled if you want to allow more leniency.

Every user or merchant can define their own fraud detection rules in this panel to control transaction flow and reduce false rejections.

Why is this important?

Many issues reported by customers regarding rejected payments are due to fraud rule settings. Ensuring these are configured appropriately helps reduce false positives and improves customer experience.

If you're unsure how to proceed, please contact your fraud management team or refer to CyberSource's official Fraud Management Guide (login may be required).
