## Additional Response with `model` { #additional-response-with-model }

You can pass to your *path operation decorators* a parameter `responses`.

It receives a `dict`: the keys are status codes for each response (like `200`), and the values are other `dict`s with the information for each of them.

Each of those response `dict`s can have a key `model`, containing a Pydantic model, just like `response_model`.

In this case, **FastAPI** will notice that there is more than one body parameter in the function (there are two parameters that are Pydantic models).

So, it will then use the parameter names as keys (field names) in the body, and expect a body like:

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    },
    "user": {

		return nil, errors.New("both the token file and the role ARN are required")
	case conf.AccessKey == "" && conf.SecretKey != "" || conf.AccessKey != "" && conf.SecretKey == "":
		return nil, errors.New("both the access and secret keys are required")
	case conf.AWSRole && (conf.AWSRoleWebIdentityTokenFile != "" || conf.AWSRoleARN != "" || conf.AccessKey != "" || conf.SecretKey != ""):
