Does anyone know which specific OAuth scope is required to successfully query /api/v2/routing/queues when using a custom Electron-based softphone client? I am implementing a desktop application that requires real-time queue status updates, and while the application grant type works flawlessly for most endpoints, I am encountering a persistent 403 Forbidden response when attempting to fetch queue details. The application has been assigned the admin role within the Genesys Cloud instance, and I have verified that the client credentials are correctly rotated via the /oauth/token endpoint. My current request payload includes standard headers with Authorization: Bearer <token>, yet the server rejects the call immediately without returning the expected queue JSON structure. I have cross-referenced the documentation and confirmed that routing:queue and routing:queue:read scopes are attached to the client registration, but the 403 error persists regardless of whether I use the client_credentials or authorization_code flows. Is there a hidden dependency on a specific user-level permission or a missing scope like routing:queue:write that is required even for read-only operations in this context?
TL;DR: scope mismatch.
This looks like a permissions issue. admin isn’t a valid OAuth scope. You need routing:queue:read. In PHP, ensure your token request includes this scope. If using PureCloudPlatformClientV2, verify the auth config. I usually cache tokens with Guzzle to avoid re-fetching.
The easiest fix here is this is to verify the exact scope string in your token request payload. Coming from Five9, I initially assumed admin was a catch-all, but CXone is strict about OAuth scopes. While routing:queue:read is correct for fetching data, if you are trying to update queue settings or assign users, you will hit another 403. You likely need routing:queue (write access) or routing:queue:write depending on your specific action.
I hit this exact wall with my Python integration. The admin role in the UI grants permissions, but the OAuth token must explicitly request the scope. If you are using the PureCloudPlatformClientV2 SDK, ensure your OAuth2Client configuration includes the correct scope list. Here is the working JSON payload structure for the token request:
{
"grant_type": "client_credentials",
"scope": "routing:queue:read routing:queue:write",
"client_id": "YOUR_CLIENT_ID",
"client_secret": "YOUR_CLIENT_SECRET"
}
Also, check if your client is cached. I found that sometimes the SDK holds onto an old token with insufficient scopes even after you update the config. Force a new token refresh by clearing the cache or using oauth2Client.refreshToken() if applicable. If you are building a custom Electron client, do not hardcode the token. Use the client_credentials flow with a secure backend to fetch tokens, as exposing client secrets in frontend code is a major security risk. Verify the response headers for x-genesys-cloud-request-id to trace the specific permission denial in the admin logs.
Ah, yeah, this is a known issue with scope resolution in client-side applications. The admin string is not a valid OAuth scope. Use routing:queue:read instead.
403 Forbidden on /api/v2/routing/queues despite admin role
const scopes = ['oauth_offline', 'routing:queue:read'];
const token = await pureCloudClient.platformClient.Auth.loginWithImplicitGrant(clientId, redirectUri, scopes);If I remember correctly, routing:queue:read is the strict requirement. admin is invalid. In your Electron app, ensure the implicit grant payload explicitly lists routing:queue:read. Verify the token via /api/v2/oauth2/introspect. If the scope is missing, the 403 persists. Check the Access-Control-Expose-Headers for debugging.
