Payouts error 121018 for Bank Account objects created after April 30, 2026

Bank Account objects created via a POST Create a Bank Account endpoint after April 30, 2026, will not be usable for payouts.

As communicated via email, from this date external accounts must be registered using the Recipient endpoints and authenticated using SCA.

If a payout request references a Bank Account created after April 30, 2026, the payout will fail with the following ResultCode and ResultMessage:

• 121018 – This payout uses a non-SCA compliant bank account. Please create via the recipient endpoint and try again.

This error will occur when a payout’s BankAccountId references a Bank Account object that was created via a POST Create a Bank Account endpoint after April 30, 2026.

To resolve the error, your platform needs to register the external account using the POST Create a Recipient endpoint. This endpoint requires you to redirect the user to authenticate the action via Mangopay’s hosted SCA session (see recipients guide for details).

Once successfully registered, the RecipientId can be used to retry the payout.
