Trigger REST API without OIC on PAAS and SAAS.

According to our client's requirement, we need to customize a program to pick and calculate some data to insert new invoice line into the same invoice after user save the invoice.

We designed to trigger a customized program by user's save action on the form to triggered REST API to insert new invoice line into the same saved invoice without running concurrent program for OIC.

The application is Oracle Fusion Cloud Applications 23D (11.13.23.10.0).

We have got information that on REST API is not allowed to be triggered on the form but need to be triggered through OIC process via concurrent program.
