Você também pode usar as outras operações:

* `@app.post()`
* `@app.put()`
* `@app.delete()`

E os mais exóticos:

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

/// tip | Dica

Você está livre para usar cada operação (método HTTP) como desejar.

There are cases where you want to tell your API **users** that your app could call *their* app (sending a request) with some data, normally to **notify** of some type of **event**.

This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

1. Copie o arquivo `main.py` para o diretório `/code` diretamente (sem nenhum diretório `./app`).

2. Execute o Uvicorn e diga a ele para importar o objeto `app` de `main` (em vez de importar de `app.main`).

Então ajuste o comando Uvicorn para usar o novo módulo `main` em vez de `app.main` para importar o objeto FastAPI `app`.

## Conceitos de Implantação

The same way you can specify a response model, you can also declare the HTTP status code used for the response with the parameter `status_code` in any of the *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

```Python

    return {"Hello": "World"}


@app.get("/items/{item_id}")

    return {"item_id": item_id, "q": q}
