Initiates a SEPA payment. The debtorAccount can be either 'iban', 'bban' (Note that some Finnish banks may currently not accept 'bban'), or 'sortCodeAccountNumber' (UK) and
the creditorAccount must be 'iban'. The currency is always 'EUR'. To enable a custom redirect, include the x-redirect-url parameter in the request header.
The callback will then include a resource_id (the payment-id) and a result (the request's status, either 'OK' or 'FAILED').
This API will return a 1426 error if consent is required and a 1428 'payment authorization required' if the payment requires SCA.
If you get error code '1428' then you have to call API '/ics/v3/payments/{paymentProduct}/{paymentId}/authorize' to get authorization URL. Once you receive url then you can use that to get
authorised with respective bank.
Additionally, payments can be initiated without debtorAccount details (iban/bban) and debtor name if the supported service for the bank includes "sepa-credit-without-debtor-details" (only for Finnish payments).
Note that initiating payments without debtor details will not apply for cross-border SEPA payments.
