# Response unmarshaller

In order to explicitly validate and unmarshal a:

- OpenAPI 3.0 spec, import `V30ResponseUnmarshaller`

- OpenAPI 3.1 spec, import `V31ResponseUnmarshaller` or `V31WebhookResponseUnmarshaller`

      from openapi_core import V31ResponseUnmarshaller

      config = Config(
         response_unmarshaller_cls=V31ResponseUnmarshaller,
      )
      openapi = OpenAPI.from_file_path('openapi.json', config=config)
      result = openapi.unmarshal_response(request, response)

You can also explicitly import `V3ResponseUnmarshaller` which is a shortcut to the latest OpenAPI v3 version.
