Antes do FastAPI 0.108.0, Starlette 0.29.0, `name` era o primeiro parâmetro.

## Chamar `uvicorn` { #call-uvicorn }

Em sua aplicação FastAPI, importe e execute `uvicorn` diretamente:

### Sobre `__name__ == "__main__"` { #about-name-main }

O objetivo principal de `__name__ == "__main__"` é ter algum código que seja executado quando seu arquivo for chamado com:

Los webhooks que defines terminarán en el esquema de **OpenAPI** y en la interfaz automática de **documentación**.

The webhooks that you define will end up in the **OpenAPI** schema and the automatic **docs UI**.

You could put your XML content in a string, put that in a `Response`, and return it:

{* ../../docs_src/response_directly/tutorial002_py39.py hl[1,18] *}

## Notes { #notes }

When you return a `Response` directly its data is not validated, converted (serialized), or documented automatically.
