WSDL

https://webservices.data-8.co.uk/bankaccountvalidation.asmx

JSON

https://webservices.data-8.co.uk/BankAccountValidation/IBANIsValid.json

Description

Checks if a BIC is a valid UK or Ireland BIC code, and retrieve additional information about the associated bank.

If an IBAN is also specified, checks if it is a potentially valid IBAN for that BIC.

Parameters

The following parameters can be supplied to this method

username	username See the available authentication methods. If you are using username & password authentication, specify the username to authenticate as. If you are using API Key authentication and you are not using the JSON, Javascript or ADO APIs, use your API Key here with the prefix `apikey-`, e.g. `apikey-ABCD-1234-EFGH-5678`
password	password If you are using username & password authentication, specify the password to use for authentication. Otherwise leave this blank.
bic	bic The BIC to validate.
iban	iban If specified, indicates the IBAN to validate along with the `bic`. Leave blank to validate the BIC only.

Results

This method returns an object containing the following fields:

Status	Status Indicates whether the method call was successful, or if some error occurred. If the `Success` field is `true`, the other results described below can be used to get the results of the method. If `Success` is `false`, some error occurred in calling the method, such as the authentication failed or the account is out of credits. The details of the error can be obtained from the `ErrorMessage` field, and any other results should be ignored
Valid	Valid Indicates if the supplied details are valid. This can be one of the following values: `Valid` - the bank account number passes the validation rules applied to the selected bank `Invalid` - the bank account number fails the validation rules applied to the selected bank `NotValidated` - no validation rules are available for the selected bank
SortCode	SortCode Returns the sort code in a standardised format with dashes
AccountNumber	AccountNumber The account number in a standardised format
BICCode	BICCode The BIC code for the bank for this branch to be used with international payments
IBAN	IBAN The IBAN number for this account to be used with international payments
BranchName	BranchName The name of the bank branch. For most high-street banks, this will be the town name the branch is located in.
ShortBankName	ShortBankName The normal accepted name of the bank
FullBankName	FullBankName The full official name of the bank
Address	Address The postal address of the branch. Note that this may not be the same as the physical location of the branch as many banks centralise all their operations
