Historically, opting-in to the Account Updater has been controlled at the Organization level, which affects ALL environments within the organization. Alternatively, the service can be controlled down to an individual payment method (card) as well. However, these options can either be too broad or too narrow to effectively and efficiently enable Account Updater for customers of merchant aggregators.
Account Updater can now be managed at an environment level as well, providing the aggregator the ability to enable the service for specific segments of their business and for individual merchants if they have a 1:1 relationship with environments. For additional implementation details, please see the Environment-Level Controls for Account Updater.
