# Corpo - Atualizações

## Atualização de dados existentes com `PUT`

Para atualizar um item, você pode usar a operação <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

Você pode usar `jsonable_encoder` para converter os dados de entrada em dados que podem ser armazenados como JSON (por exemplo, com um banco de dados NoSQL). Por exemplo, convertendo `datetime` em `str`.
