eac_*) is a bank account linked to a party. It’s the bridge between Natural Wallets and the banking system: the source of deposits, the destination of withdrawals, and a funding option when fulfilling a Payment request. List yours with GET /external-accounts, then follow Deposit and withdraw.
Linking
Link your own bank account in the dashboard. Customers link their own bank accounts the same way, from their own Natural dashboard.Removing
Remove an external account withDELETE /external-accounts/{externalAccountId} from a user session or party API key; new deposits and withdrawals against it stop. If the account backs your card payments, link another verified account first.
