## Import `Form` { #import-form }

Import `Form` from `fastapi`:

## Define `Form` parameters { #define-form-parameters }

Create form parameters the same way you would for `Body` or `Query`:

# Parâmetros de Cookie { #cookie-parameters }

Você pode definir parâmetros de Cookie da mesma maneira que define parâmetros com `Query` e `Path`.

## Importe `Cookie` { #import-cookie }

Primeiro importe `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## Declare parâmetros de `Cookie` { #declare-cookie-parameters }

Então declare os parâmetros de cookie usando a mesma estrutura que em `Path` e `Query`.

# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

## Crea un SDK de TypeScript { #create-a-typescript-sdk }

Empecemos con una aplicación simple de FastAPI:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Nota que las *path operations* definen los modelos que usan para el payload del request y el payload del response, usando los modelos `Item` y `ResponseMessage`.
