CXone OAuth client division scoping for multi-tenant BPO access

We’re building a unified API gateway for our BPO clients. Each client sits in their own CXone division. The goal is to have a single OAuth client credential set that can be scoped dynamically based on the incoming request header, rather than maintaining separate clients per tenant.

Tried setting the X-Genesys-Organization-Name header during the token request, but the resulting access token still carries the global scope. When I hit /api/v2/users, it returns users from all divisions instead of just the target one.

Here’s the token exchange payload:

{
 "grant_type": "client_credentials",
 "client_id": "our-shared-client-id",
 "client_secret": "secret",
 "scope": "user:read"
}

The docs mention division-scoped tokens, but the examples are vague on how to enforce that at the auth layer. Is there a specific claim or scope parameter I’m missing? Or do I have to fall back to impersonation with a user token for each division?

Feeling stuck on the token generation step. The API calls work fine once I have a user token, but getting there efficiently is the bottleneck.

That approach won’t work. The OAuth token issuance is strictly bound to the client credentials, which are tied to a single division by default. You can’t swap the division context after the token is minted using just a header. The token is the scope.

If you need a unified gateway, you have two real options. First, use a multi-tenant client with divisionless scopes if you only need global resources. Second, and more likely for BPOs, you need to maintain separate client IDs per division. Your gateway should inspect the X-Genesys-Organization-Name header, look up the correct client ID and secret in a secure vault, and generate a fresh token for that specific request.

Here is how the flow should look in your gateway logic. Don’t try to reuse the token across divisions.

# Pseudo-code for gateway logic
def get_token_for_division(div_name):
 creds = vault.fetch(div_name) # Get specific client_id/secret
 return auth_client.token_request(client_id=creds.id, client_secret=creds.secret)

It’s extra overhead but it’s the only way to keep the security model intact.
