Braintree’s elaborate AVS and CVV settings allow you to reject transactions that do not meet your fraud filter criteria. You can access AVS settings via Settings >> Processing >> Basic Credit Card Fraud Tools >> AVS and >> CVV on your Braintree dashboard.
Note: Remember to make sure your settings on Chargebee’s field configuration page match the settings you choose here.
If you are using the V2 checkout pages, navigate to Settings >> Customer-facing essentials >> Checkout and Self-Serve Portal >> Field Configurations (on the left panel) >> Card Information to choose what information would like to mark as mandatory.
On the other hand, if your site has V3 checkout pages, navigate to Settings >> Customer-facing essentials >> Checkout and Self-Serve Portal >> Fields >> Payments (on the left panel). Here you can enable the fields and set them as mandatory by clicking on the edit icon. Screenshot for your reference.
If a transaction fails to meet the configured AVS criteria, it is declined at Braintree before processing - this is called a gateway rejection. AVS gateway rejections are accompanied by error codes and responses that reflect which filter was tripped, find a list of them here.
