Das einzig Neue ist `callbacks=invoices_callback_router.routes` als Argument für den *Pfadoperation-Dekorator*. Wir werden als Nächstes sehen, was das ist.

## Dokumentation des Callbacks

Der tatsächliche Callback-Code hängt stark von Ihrer eigenen API-Anwendung ab.

Und er wird wahrscheinlich von Anwendung zu Anwendung sehr unterschiedlich sein.

Es könnten nur eine oder zwei Codezeilen sein, wie zum Beispiel:

```Python

# Omgevingsvariabelen

/// tip

Als je al weet wat "omgevingsvariabelen" zijn en hoe je ze kunt gebruiken, kun je deze stap gerust overslaan.

///

Een omgevingsvariabele (ook bekend als "**env var**") is een variabele die **buiten** de Python-code leeft, in het **besturingssysteem** en die door je Python-code (of door andere programma's) kan worden gelezen.

                } else {
                    final String str = String.valueOf(c);
                    if (StringUtil.isAsciiPrintable(str)) {
                        buf.append(c);
                    } else {
                        buf.append(URLEncoder.encode(str, charset));
                    }
                }

No arquivo `main.py` você tem seu aplicativo **FastAPI**:


{* ../../docs_src/app_testing/main.py *}

### Arquivo de teste

Então você poderia ter um arquivo `test_main.py` com seus testes. Ele poderia estar no mesmo pacote Python (o mesmo diretório com um arquivo `__init__.py`):

``` hl_lines="5"

│   ├── main.py
│   └── test_main.py

references dedicated tutorials for configuring one-way "Active-Passive" and two-way "Active-Active" bucket replication.

To replicate objects in a bucket to a destination bucket on a target site either in the same cluster or a different cluster, start by enabling [versioning](https://docs.min.io/community/minio-object-store/administration/object-management/object-versioning.html) for both source and destination buckets. Finally, the target site and the destination bucket need to be configured on...
