Update credit limit on credit authorization

Summary:

We have an external non oracle system for Order Management of some products ,

and using fusion order management for most of the products.

so need to expose the available credit limit and update the consumed credit amount in real time.

I understand we can expose a webservice CreditCheckingService so that external system can check the credit limit.

Doc ID 2482760.1

But once the order is booked in external system , how to reflect the consumed credit limit in oracle fusion?

Is there a separate API?
