# Doppler

> Resolve workload secrets with a scoped Doppler service token.

Use a Doppler service token for the project and configuration that Towbar workloads need. The token belongs in the protected control-plane YAML file, not in a repository or workload manifest. Towbar resolves references during deployment and does not return secret values to the dashboard.

```yaml title="/etc/towbar/towbar.yml" theme={"system"}
integrations:
  doppler:
    enabled: true
    token: "<service-token>"
```

Run `sudo towbar config validate` and `sudo towbar restart`. Confirm that Doppler appears under **Manage → Integrations → External secrets**. A configured status does not test token access to a project or config. Follow the [external-secret source guide](/docs/secrets/external) and deploy a non-production workload to verify access.

If a deployment cannot load its secrets, check the project/configuration covered by the token and whether the token was revoked. Apply a replacement service token in YAML, restart, verify a test deployment, and then revoke the previous token.

    The Doppler page confirms that Towbar loaded the runtime configuration; test
    a reference to verify remote access.
