# Cookie Parameters

You can define Cookie parameters the same way you define `Query` and `Path` parameters.

## Import `Cookie`

First import `Cookie`:

//// tab | Python 3.10+

```Python hl_lines="3"
{!> ../../../docs_src/cookie_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../../docs_src/cookie_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3"
{!> ../../../docs_src/cookie_params/tutorial001_an.py!}
```

////

//// tab | Python 3.10+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="1"
{!> ../../../docs_src/cookie_params/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="3"
{!> ../../../docs_src/cookie_params/tutorial001.py!}
```

////

## Declare `Cookie` parameters

Then declare the cookie parameters using the same structure as with `Path` and `Query`.

The first value is the default value, you can pass all the extra validation or annotation parameters:

//// tab | Python 3.10+

```Python hl_lines="9"
{!> ../../../docs_src/cookie_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="9"
{!> ../../../docs_src/cookie_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="10"
{!> ../../../docs_src/cookie_params/tutorial001_an.py!}
```

////

//// tab | Python 3.10+ non-Annotated

/// tip

///

```Python hl_lines="7"
{!> ../../../docs_src/cookie_params/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+ non-Annotated

/// tip

```Python hl_lines="9"

```

////

/// note | "Technical Details"

`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.

///

## Recap

Declare cookies with `Cookie`, using the same common pattern as `Query` and `Path`.
