### Create the callback *path operation*

To create the callback *path operation* use the same `APIRouter` you created above.

It should look just like a normal FastAPI *path operation*:

* It should probably have a declaration of the body it should receive, e.g. `body: InvoiceEvent`.

    VersionsMetadata(Artifact artifact, Date timestamp) {
        super(createRepositoryMetadata(artifact), (Path) null, timestamp);
        this.artifact = artifact;
    }

    VersionsMetadata(Artifact artifact, Path path, Date timestamp) {
        super(createRepositoryMetadata(artifact), path, timestamp);
        this.artifact = artifact;
    }

    private static Metadata createRepositoryMetadata(Artifact artifact) {

## Mounting a **FastAPI** application

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application

First, create the main, top-level, **FastAPI** application, and its *path operations*:

```Python hl_lines="3  6-8"
{!../../docs_src/sub_applications/tutorial001.py!}
```

path-key@^3.1.0:
  version "3.1.1"
  resolved "https://registry.yarnpkg.com/path-key/-/path-key-3.1.1.tgz#581f6ade658cbba65a0d3380de7753295054f375"
  integrity sha512-ojmeN0qd+y0jszEtoY48r0Peq5dwMEkIlCOu6Q5f41lfkswXuKtYrhgoTpLnyIcHm24Uhqx+5Tqm2InSwLhE6Q==

path-parse@^1.0.7:
  version "1.0.7"

しかし、`Response` を直接返すと、データは自動的に変換されず、ドキュメントも自動生成されません (例えば、生成されるOpenAPIの一部としてHTTPヘッダー `Content-Type` に特定の「メディアタイプ」を含めるなど) 。

しかし、*path operationデコレータ* に、使いたい `Response` を宣言することもできます。

*path operation関数* から返されるコンテンツは、その `Response` に含まれます。

そしてもし、`Response` が、`JSONResponse` や `UJSONResponse` の場合のようにJSONメディアタイプ (`application/json`) ならば、データは *path operationデコレータ* に宣言したPydantic `response_model` により自動的に変換 (もしくはフィルタ) されます。

/// note | "備考"

```Python hl_lines="11-14"
{!> ../../docs_src/body_fields/tutorial001.py!}
```

////

`Field` funktioniert genauso wie `Query`, `Path` und `Body`, es hat die gleichen Parameter, usw.

/// note | "Technische Details"

Tatsächlich erstellen `Query`, `Path` und andere, die sie kennenlernen werden, Instanzen von Unterklassen einer allgemeinen Klasse `Param`, die ihrerseits eine Unterklasse von Pydantics `FieldInfo`-Klasse ist.
