## Consequences

### Positive Consequences

* **Improved consistency**: The codebase has a uniform language standard
* **Easier onboarding**: New contributors have clear guidance on which spelling to use
* **Better searchability**: Finding code and documentation becomes more predictable
* **Reduced review friction**: Less time spent on spelling corrections during PR reviews

///

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

{* ../../docs_src/response_model/tutorial002_py310.py hl[7,9] *}

Para usar `EmailStr`, primeiro instale [`email-validator`](https://github.com/JoshData/python-email-validator).

Certifique-se de criar um [ambiente virtual](../virtual-environments.md), ative-o e então instale-o, por exemplo:

```console
$ pip install email-validator
```

ou com:

```console
$ pip install "pydantic[email]"
```

///

Neste caso, o **FastAPI** nunca tocará ou se importará com o `__init__`, nós vamos utilizar diretamente em nosso código.

## Crie uma instância { #create-an-instance }

Nós poderíamos criar uma instância desta classe com:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[18] *}

## Una aplicación con webhooks { #an-app-with-webhooks }

Cuando creas una aplicación de **FastAPI**, hay un atributo `webhooks` que puedes usar para definir *webhooks*, de la misma manera que definirías *path operations*, por ejemplo con `@app.webhooks.post()`.

/// info

Les webhooks sont disponibles dans OpenAPI 3.1.0 et versions ultérieures, pris en charge par FastAPI `0.99.0` et versions ultérieures.

Pour utiliser les formulaires, installez d'abord [`python-multipart`](https://github.com/Kludex/python-multipart).

Assurez-vous de créer un [environnement virtuel](../virtual-environments.md), de l'activer, puis installez-le, par exemple :

```console
$ pip install python-multipart
```
