Initiates a batch domestic payment with multiple creditors. Each payment in the batch shares the same debtor account.
The debtorAccount can be either 'iban', 'bban', or 'sortCodeAccountNumber'. The creditorAccount in each creditor entry can be either 'iban', 'bban', or 'sortCodeAccountNumber' (UK).
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.
NOTE: The max limit for creditors in a batch payment is 20.
