# Cookie Parameters { #cookie-parameters }

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

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

First import `Cookie`:

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

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

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

# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

                        res.addCookie(cookie);
                        if (logger.isDebugEnabled()) {
                            logger.debug(
                                    "Stored search parameters in cookie: name={}, size={}, maxAge={}, path={}, domain={}, secure={}, httpOnly={}, sameSite={}",
                                    cookie.getName(), encoded.length(), cookie.getMaxAge(), cookie.getPath(), cookie.getDomain(),

        final Cookie cookie = new Cookie(cookieName, userCode);
        cookie.setMaxAge(age);
        cookie.setHttpOnly(httpOnly);
        if (StringUtil.isNotBlank(cookieDomain)) {
            cookie.setDomain(cookieDomain);
        }
        if (StringUtil.isNotBlank(cookiePath)) {
            cookie.setPath(cookiePath);
        }
        cookie.setSecure(isSecureCookie());
        LaResponseUtil.getResponse().addCookie(cookie);
    }

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

## Import `Header` { #import-header }

First import `Header`:

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

## Declare `Header` parameters { #declare-header-parameters }

Then declare the header parameters using the same structure as with `Path`, `Query` and `Cookie`.
