Is there any APIs available to create bank account from Bill management page in Oracle fusion

Is there any APIs available to create bank account from Bill management page in Oracle fusion by passing the following fields alone

Bank account number

Country 

Currency 

Account type

Routing number

Using the below WSDL we are able to create the bank account. The external bank account will be available in the customer profile and invoices as well (in the payment section).

SOAP API: https://servername/fscmService/ExternalBankAccountServiceV2?WSDL

Payload details:

Bank name

Branch name (Routing number i.e. Branch number)

Bank account number

Country 

Currency 

Account type

AccountOwnerPartyId

 

But in the Bill management page, from the front end we are able to create bank accounts by passing Routing number, account type and account number. There is no validation and accounts are getting created.
