Oracle Flexcube REST API Automation

I need to plug an existing REST-based service into Oracle Flexcube so that, when a user selects “Open Customer,” the page launches with all personal information already populated. The motivation is pure automation: eliminating manual data entry while keeping the standard Flexcube flow intact.

Here is what matters most:
• The service that supplies the data is already live and documented—your job is to consume it, map its JSON response to the correct Flexcube fields, and invoke the page in create mode.
• Only personal information (name, date of birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now.
• The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process.

Deliverables I expect:
1. Integration code (Java / PL-SQL wrapper or preferred Flexcube extension) committed to a Git repository.
2. Mapping document that shows each JSON field and its corresponding Flexcube column.
3. Simple test script or Postman collection proving the end-to-end flow.
4. Brief deployment notes so our ops team can move it from UAT to production without a hitch.

If you’ve worked with FCUBS web services or any Flexcube extensibility framework, this should be straightforward. Let’s automate this touchpoint and save the team from re-typing data ever again.
