Automatic Billing Updater (ABU) is a web service that provides access to updated account credentials (cards). This can be leveraged by Merchant/Acquirers/Payment Service Providers to ensure that they always have their customers’ most up to date card credentials for recurring and card-on-file payments.
Simply put, ABU allows card details to be updated automatically in the event they are no longer valid. Types of updates include:

  • Expiration dates
  • Replacement card numbers
  • Account closures
  • Issuer brand changes to Visa and MasterCard
