Are there any APIs to create an Invoice in Oracle Payables?

Question

Hi,
We have a requirement to import the invoices from the operational systems. We will be making approximately 7,000 checks a day. We need to import all these payments information into Oracle Payables as Invoices and then process the payments out of Oracle payments module. We are on EBS 12.1.1
Were there any APIs to create the invoices directly in Payables as it comes from custom application? We could use payables open interface but as we would like to integrate the payables module with custom application it would be nice if invoice creates directly in Payables through APIs.
Thanks,
