We’re trying to automate our DFO channel registration updates via a GitHub Actions pipeline. The goal is to generate a long-lived access token using the client credentials flow so the script can run without human intervention.
I’ve set up a service account in CXone with the necessary admin:api scopes. The client ID and secret are stored as secrets in the repo. When I run the curl command locally, it works fine. But in the pipeline, it consistently returns a 401.
Here’s the exact request we’re sending:
curl -X POST 'https://api.nice.incontact.com/oauth2/token' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=client_credentials&client_id=MY_CLIENT_ID&client_secret=MY_CLIENT_SECRET'
The response body is minimal:
{
"error": "invalid_client",
"error_description": "Client authentication failed"
}
I’ve triple-checked the secrets. They’re correct. I can log in with the same service account credentials manually in the UI. The client ID matches what’s shown in the API credentials section.
Is there a specific header or scope requirement I’m missing for the client credentials flow? The standard OAuth docs for CXone are pretty light on CI/CD use cases. I assumed client_credentials would work out of the box for service-to-service auth, but maybe there’s a catch.
Also, does the token expire immediately if the service account isn’t active? We have a rotation policy that might be locking it. But the error says invalid_client, not invalid_grant or unauthorized_client. That points to bad credentials, but the credentials are definitely right.
Any ideas? I’m stuck. The pipeline is blocked until I get this token generation working.
