  "serviceTransactionId": "48ef3043-1g3i-8hgg-25h1-608i15272743"
}
```

{% hint style="info" %}
Authentication errors (`401`/`403`) are rejected by the **gateway before reaching the service** and **do** not use the envelope `serviceResultCode`. Platform validation errors use the format `application/problem+json`. See [Error handling](/docs.facephi-en/rest-api/identity-api/identity-api-reference/onboarding/kyc/nigeria.md#manejo-de-errores) for details of the three response forms.
