Each service provider is required to implement and return their own error messages using the error codes specified as GeneralBankCode. Additionally, errors from the originating system are returned. Standardized web services of banks and savings banks are based on SOAP 1.2 with exception handling. If an exception occurs, the web service returns an error message of type IOBSFault.
