Creation of Bank Drafts

We have built a developer app on Blackbaud where we are creating and posting invoices to our client's Accounts Payable ledger via SKY API.

However, we seem to be unable to create Bank Draft payments against these invoices using the API. In the API documentation, we haven't located any API that is specifically for recording a payment against the invoice.

Is there an API within SKY API that allows us to post dated Bank Draft payments against invoices?

We tried the PATCH Invoice Edit API filling in the information within invoice_payment_detail, specified the bank draft type and the account, but because there's no field for payment date, it just says in the UI that a bank draft has been scheduled for whatever the due date is. But let's say the due date is 1/31 and the bank draft already happened on 1/15, we'd want to be able to record it accurately for reconciliation purposes.

We also tried the Create Payment POST API and passing the “starting check number” as what the account sub-ledger specified the Bank Draft's next number was, but it just created a manual check.

We checked through all the KB articles related to Bank Drafts, but nothing gave us the answer we were looking for.
