OAuth Client Division Scoping for Multi-Tenant BPO Integration

No idea why this is happening, my OAuth client configuration is not respecting division-level restrictions when attempting to isolate access for a multi-tenant BPO environment.

We are building a Salesforce integration that requires strict data isolation. Each client in our BPO operates within their own Genesys Cloud division. The requirement is that a specific OAuth client, used by our middleware, should only be able to read/write resources within the assigned division, not others.

I have configured the client in the Admin console with specific Division Scopes. However, when I generate a token and attempt to call the /api/v2/users endpoint, I can still see users from other divisions if the token is used with an admin-level user context, or the request fails with a 403 Forbidden if the user lacks cross-division permissions.

Here is my current configuration payload sent to the /api/v2/oauth/clients endpoint:

name: "BPO-Client-Isolated"
client_type: "confidential"
grant_type: "client_credentials"
scopes:
 - "user:read"
 - "user:write"
divisions:
 - id: "a1b2c3d4-e5f6-7890-abcd-ef1234567890"
 name: "Client-A-Division"
allowed_origins:
 - "https://middleware.bpo.com"

When I use the resulting access token to fetch user details, the response includes users from Client-B-Division if the authenticated user is a super-admin. I expected the Division Scope to hard-filter the results at the API layer, regardless of the user’s inherent permissions.

Is there a specific flag or additional scope required to enforce division isolation at the OAuth level? Or am I misunderstanding how Division Scopes interact with user permissions in the Genesys Cloud API? I need a code-level solution to ensure no data leakage between tenants.

You should probably look at at the division ID parameter in your token request payload. Ensure you are passing the correct division ID as specified in this guide: https://support.nicecxone.com/articles/oauth-division-scoping
