CXone Client Credentials Grant returning 403 Forbidden

NICE CXone API & Integrations

Trying to get a token from /api/v2/oauth/token using the client_credentials grant. The endpoint returns 403 Forbidden even though the app ID and secret are correct.

POST /api/v2/oauth/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials&client_id=MY_APP_ID&client_secret=MY_SECRET

Verified the credentials work in Postman but not in our C# code. Is there a specific scope required for this grant type that I’m missing?

Check your app permissions in the developer portal. The client needs the analytics:report:read scope at minimum, or the token generation fails silently with a 403.
