## TL;DR

Do not mix the two auth planes: OAuth2 client credentials with the cloudv2-production.redpanda.cloud audience are for the control plane API; SASL/SCRAM username and password are for the Kafka data plane.

## Fix

1. Do not mix the two auth planes: OAuth2 client credentials with the cloudv2-production.redpanda.cloud audience are for the control plane API; SASL/SCRAM username and password are for the Kafka data plane.
   Expected: you can confirm this matches your situation.

## When to use

- You are setting up or using this Redpanda Cloud has separate auth planes feature.
- The symptom matches: OAuth2 for control plane, SCRAM for Kafka.

## When NOT to use

- Unrelated Redpanda Cloud has separate auth planes issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Compatibility

Reported against Redpanda Cloud has separate auth planes.

## Variant phrasings

### OAuth2 for control plane, SCRAM for Kafka

## Why it happens

Official docs (redpanda-data/skills, cloud-dedicated skill): documents the two-plane auth gotcha that trips agents automating Redpanda Cloud. The control plane uses OAuth2 client credentials: create a client ID and secret in the Cloud console (Clients tab under Users), then request a token with grant_type=client_credentials and audience=cloudv2-production.redpanda.cloud, passing it as a Bearer token on every API call. The data plane (Kafka) uses separate SASL/SCRAM credentials. Serverless clusters are also managed through a separate ServerlessClusterService API, not the ClusterService used for Dedicated/BYOC.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
