post https://api.cert.zerohash.com/payments/external_accounts//close
This endpoint is used to close an account linked to a participant.
Whether integrated via API or SDK, the behavior for closing linked bank accounts, or external accounts, is the same. If an external account is closed, it will not show as a funding option in the SDK.
Closing an external account severs the tie between Zero Hash and the customer bank account. It does not unlink the bank account from Plaid or close the bank account outright.
