Distribution Management: REST API OAuth2 integration returns 401 Unauthorized blocking journal sync

We’re implementing automated journal entry posting from our legacy distribution system to Oracle Fusion Cloud SCM 23c using REST APIs. The integration worked fine in our sandbox environment, but production consistently returns 401 Unauthorized errors.

Our OAuth2 token generation succeeds, but when we attempt to POST distribution journal entries, the API gateway rejects the request:


POST /fscmRestApi/resources/11.13.18.05/distributionJournals
Authorization: Bearer eyJhbGc...
HTTP/1.1 401 Unauthorized
{"title":"Unauthorized","detail":"Invalid token scope"}

We’re using client credentials flow with the standard fusion_apps_api scope. The token validates successfully against the token introspection endpoint, but journal posting fails. We suspect this might be related to multi-tenant token validation or missing API gateway headers specific to our production tenant. Has anyone encountered scope or claims issues with distribution management APIs in multi-tenant deployments?

Thanks for the pointer. I added the urn:opc:resource:consumer::all scope to our token request, but still getting 401. Interestingly, when I decode the JWT token, I can see both scopes are present in the claims. The token introspection also confirms these scopes. Could this be a tenant-specific configuration issue? Our sandbox and production are on different data centers (us2 vs us6).

I updated the token request with the audience parameter and added the X-Oracle-RF-Token header, but now getting a different error: 403 Forbidden with “Insufficient privileges for Distribution Journal creation”. Progress, I guess? The authentication is working now. Seems like a role mapping issue in our connected app.

Multi-tenant deployments require the X-Oracle-RF-Token header for cross-tenant API calls, even within the same organization. Your production environment likely has stricter tenant isolation. Add this header with your access token value. Also, verify that your connected app registration in production has the same callback URLs and is activated for the correct business unit. The API gateway validates tenant context before checking authorization scopes.

Check your OAuth2 scope configuration first. For distribution journal APIs in 23c, you need the urn:opc:resource:consumer::all scope in addition to fusion_apps_api. The standard scope only grants read access to most endpoints. Also verify your client registration includes the Distribution Management role mapping.

That 403 confirms your OAuth2 setup is correct now. For distribution journal posting, your connected app needs explicit assignment of the Distribution Manager role in production. Go to Setup and Maintenance → Manage Connected Applications, find your app, and under Scope Mappings, add SCM_DISTRIBUTION_MANAGER_JOB. Also verify the user mapped to your client credentials has Create Distribution Journal privilege in the Distribution Management security console.
