Hello,
We registered a System (backend) application in the Oracle Health Developer Portal for integrating with Cerner Millennium using FHIR R4 APIs. The app is active and we have a client ID and client secret.
We requested access to:
- Patient (read, search)
- Encounter (read, search, create, update)
- DocumentReference (read, search, create, update)
- ChargeItem (read, search, create)
Our intended setup is backend-only, using OAuth 2.0 client_credentials, without SMART launch or user interaction.
Currently, the account is marked as LIMITED, and we are unable to authenticate or make API requests with our credentials.
Could you please clarify:
- Whether system OAuth scopes must be explicitly enabled by Oracle Health for backend access.
- What the LIMITED account status means and how it can be removed.
- Any additional steps required to enable backend FHIR access for a system app.
Application ID: cb915c06-040d-4e46-a14b-5b82a4461be6.
The response I get when I send a request in postman:

Thank you.
