# Response Cookies
|
||||
|
||||
## Use a `Response` parameter
|
||||
|
||||
You can declare a parameter of type `Response` in your *path operation function*.
|
||||
|
||||
And then you can set cookies in that *temporal* response object.
|
||||
|
||||
```Python hl_lines="1 8-9"
|
||||
{!../../../docs_src/response_cookies/tutorial002.py!}
|
||||
```
|
||||
|
||||
And then you can return any object you need, as you normally would (a `dict`, a database model, etc).
|
||||
|
||||
And if you declared a `response_model`, it will still be used to filter and convert the object you returned.
|
||||
|
||||
**FastAPI** will use that *temporal* response to extract the cookies (also headers and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.
|
||||
|
||||
You can also declare the `Response` parameter in dependencies, and set cookies (and headers) in them.
|
||||
|
||||
## Return a `Response` directly
|
||||
|
||||
You can also create cookies when returning a `Response` directly in your code.
|
||||
|
||||
To do that, you can create a response as described in [Return a Response Directly](response-directly.md){.internal-link target=_blank}.
|
||||
|
||||
Then set Cookies in it, and then return it:
|
||||
|
||||
```Python hl_lines="10-12"
|
||||
{!../../../docs_src/response_cookies/tutorial001.py!}
|
||||
```
|
||||
|
||||
!!! tip
|
||||
Keep in mind that if you return a response directly instead of using the `Response` parameter, FastAPI will return it directly.
|
||||
|
||||
So, you will have to make sure your data is of the correct type. E.g. it is compatible with JSON, if you are returning a `JSONResponse`.
|
||||
|
||||
And also that you are not sending any data that should have been filtered by a `response_model`.
|
||||
|
||||
### More info
|
||||
|
||||
!!! note "Technical Details"
|
||||
You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.
|
||||
|
||||
**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.
|
||||
|
||||
And as the `Response` can be used frequently to set headers and cookies, **FastAPI** also provides it at `fastapi.Response`.
|
||||
