Usage of fhir-ehr endpoint

Pappu kumarJul 25 2025

Workflow or API calls:

Reminder: If this is referring to a client domain or EHR activity—not the public sandbox—do not include API request data or live patient data.

Background Information:

Not able to call the fhir ehr api using the open sandbox tenant id.
Developer questions:

Can we use the open sandbox tenant id and my system app credentials and authenticate to fhir-ehr.cerner.com . As a part of my poc i was earlier using the fhir-open.cerner.com but now i want to test the fhir-ehr.cerner.com, will it be possible to do some API call using the same tenant id which is provided in the open sandbox. I tried testing this flow but i am getting the insufficient scope error but i am giving the same scope which i was using in the fhir-open and was able to get the token and call the API.

Are you developing on behalf of an Oracle Health client?
If so, which client:

Application's Client ID and App ID, if relevant:

Client ID
cd9b1105-4737-41be-a111-5c298d95bdc1

Expected Result:

An access token

Actual Result:

{

"resourceType": "OperationOutcome",

"issue": \[

    {

        "severity": "error",

        "code": "forbidden",

        "diagnostics": "Bearer realm=\\"fhir-ehr.cerner.com\\", error=\\"insufficient\_scope\\"",

        "expression": \[

            "http.Authorization"

        \]

    }
