## OpenAPI

````yaml GET /employees/{employee}/audit_trail
openapi: 3.1.0
info:
  title: Stampfactory API
  version: 1.0.0
  description: >-
    REST API für die Stampfactory Zeiterfassungs- und
    Personalverwaltungsplattform.


    ## Basis-URL


    Jeder Mandant hat eine eigene Subdomain: `https://{tenant}.stamp.eu/rest/…`.

    Custom Domains werden unterstützt; der Pfad-Präfix ist immer `/rest`.

    Authentifizierung über `POST /rest/login` (Bearer-Token, Laravel Sanctum).


    ## Datenformate (verbindlich, ADR 0005)


    | Typ | Format | Beispiel |

    |---|---|---|

    | Dauer (Anzeige) | String `HH:MM:SS.mmm`, Feldname ohne Suffix |
    `"08:00:00.000"` |

    | Dauer (Rohwert) | Integer Millisekunden, Feldname mit Suffix `_ms` |
    `28800000` |

    | Datum | ISO 8601 (`YYYY-MM-DD`) | `"2026-07-25"` |

    | Fachliche Zeitstempel (Stempelungen, Korrekturen) | ISO 8601 in
    Mandanten-Zeitzone | `"2026-07-25T08:00:00+02:00"` |

    | Technische Metadaten (`created_at`, `updated_at`) | ISO 8601 UTC |
    `"2026-07-25T06:00:00+00:00"` |

    | IDs | UUID bzw. TypeID-String | `"9d3f…"` |

    | Arbeitszeit-Flags | Integer-Bitmaske (`flags`), Bits siehe
    `WorkingTimeFlag` | `512` = Feiertag |

    | Monats-Perioden | `YYYY-MM` | `"2026-07"` |


    ## Responses


    Erfolgs-Responses liefern die fachliche Payload unter `data`

    (dokumentierte Ausnahmen: `POST /rest/terminal/{code}` und `/rest/mobile`).

    Listen sind, wo paginiert, im Laravel-Paginator-Format (`data` + `links` +
    `meta`).


    ## Fehlerformat


    Alle Fehler (4xx/5xx) folgen einem einheitlichen Envelope:


    ```json

    {
      "request_id": "…",
      "timestamp": "2026-07-25T06:00:00Z",
      "message": "Menschlich lesbare Meldung",
      "field_errors": { "feld": ["Meldung"] },
      "errors": [{ "title": "…", "detail": "…", "type": "https://docs.stampfactory.eu/errors#…", "_meta": { } }]
    }

    ```


    `field_errors` erscheint bei Validierungsfehlern (422). Endpoint-spezifische

    Zusatzdaten (z. B. `warnings`, `earliest`, `code`) stehen kanonisch in

    `errors[0]._meta`; Top-Level-Duplikate sind eine
    Übergangs-Kompatibilitätsschicht.

    Die `type`-URLs verlinken auf die Fehlerdokumentation.
