FormatIBAN to be used for payment or to be checked
- IBAN / BIC will be validated.
- Only capital letters and digits, no spaces
- It's not checked whether IBAN and BBAN (Bankcode/Bankaccount) refer to the same account or whether the account does exist.
- For some countries IBAN, BIC will be splitted into bankcode, bankaccount automatically
- If both (bankcode/bankaccount and IBAN) are submitted, IBAN is splitted into bankcode/bankaccount and IBAN is used for processing - bankcode/bankaccount parameters are ignored.
