## Write the callback documentation code

This code won't be executed in your app, we only need it to *document* how that *external API* should look like.

But, you already know how to easily create automatic documentation for an API with **FastAPI**.

Um objeto "chamável" em Python é qualquer coisa que o Python possa "chamar" como uma função

Então se você tiver um objeto `alguma_coisa` (que pode *não* ser uma função) que você possa "chamar" (executá-lo) dessa maneira:

```Python
something()
```

ou

```Python
something(some_argument, some_keyword_argument="foo")
```

Então esse objeto é um "chamável".

## Classes como dependências

```Python
contents = myfile.file.read()
```

/// note | Detalhes técnicos do `async`

Quando você utiliza métodos assíncronos, o **FastAPI** executa os métodos do arquivo em uma threadpool e espera por eles.

With the Dependency Injection system, you can also tell **FastAPI** that your *path operation function* also "depends" on something else that should be executed before your *path operation function*, and **FastAPI** will take care of executing it and "injecting" the results.

Other common terms for this same idea of "dependency injection" are:

* resources
* providers
