+# Response Cookies { #response-cookies }
+
+## Use a `Response` parameter { #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.
+
+{* ../../docs_src/response_cookies/tutorial002.py hl[1, 8:9] *}
+
+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 { #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:
+
+{* ../../docs_src/response_cookies/tutorial001.py hl[10:12] *}
+
+/// 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 { #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`.
