How to Create Custom BPM Workflow in Oracle Fusion for Supplier Creation/Update via OIC

Hello Community,

We have a business use case where an external system calls an OIC integration, passing supplier attributes in the request payload to create or update a supplier in Oracle Fusion. The OIC integration performs business validations and then invokes Fusion REST APIs to create/update the supplier. However, when using the REST APIs, the standard Supplier BPM workflow is not being triggered.

Our requirement is to ensure that supplier creation or update in Fusion only happens after a business approval. We ideally want to trigger a custom BPM workflow after the OIC validations are complete, route the approval process, and only after approval proceed to call the Fusion REST API for supplier creation or update.
