Subaccount network and regional configurations which determine the available networks and geographies during card enrollment.

The countries property for each network accepts either:

• An array of ISO 3166 alpha-3 country codes (e.g. ["USA", "CAN"])
• The string "*" to inherit all countries from the parent account's capabilities for that network

When "*" is used, the subaccount automatically reflects the parent account's current country list. If the parent account's capabilities change, subaccounts using "*" will inherit the updated countries. API responses always return the resolved country list, never the "*" literal.

The single and bulk enrollment configurations are not required when creating a subaccount, but if not provided they will default to the same country list as the main countries property for that network. The supported card types for single and bulk enrollment is CONSUMER, while the supported funding card types is DEBIT. If not provided, the block rules for both card types will default to the parent account's default block rule for that network and enrollment level.

To set the default rule on the parent account, please reach out to your account manager or support.
