Although you use `Depends` in the parameters of your function the same way you use `Body`, `Query`, etc, `Depends` works a bit differently.

You only give `Depends` a single parameter.

This parameter must be something like a function.

                            },
                        },
                    },

                    "parameters": [
                        {
                            "required": True,
                            "schema": {"title": "Item Id"},
                            "name": "item_id",

```

as it will use that `None` as the default value, and that way make the parameter **not required**.

The `Union[str, None]` part allows your editor to provide better support, but it is not what tells FastAPI that this parameter is not required.

///

Then, we can pass more parameters to `Query`. In this case, the `max_length` parameter that applies to strings:

```Python

            Map<String, Object> parameters = new HashMap<>();
            // NOTE: These parameter names _must_ match the setter names in ReleaseNotesTransformer
            parameters.put("baseCss", getBaseCssFile().get().getAsFile());
            parameters.put("releaseNotesCss", getReleaseNotesCssFile().get().getAsFile());

# Cookie Parameters

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

## Import `Cookie`

First import `Cookie`:
