Account Validation Plus Name

Phixius participants currently utilize an API based on the Afinis Account Validation API as part of the Phixius AAV (ACH Account Validation) service. The original Afinis API for account validation and the Phixius AAV API will continue to be supported to avoid any issues with current implementations.  This is a new API that will validate account/routing number status, AND provide the owner name on the account.
