#### Return *enumeration members*

You can return *enum members* from your *path operation*, even nested in a JSON body (e.g. a `dict`).

They will be converted to their corresponding values (strings in this case) before returning them to the client:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

In your client you will get a JSON response like:

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

### Enablement

Features and components can be individually or collectively enabled or disabled. If a feature is disabled, all of its
components are disabled, regardless of their component-level enablement. If a feature is enabled, all of its components
are enabled, unless they are individually disabled. For example:

```yaml
    telemetry:
      enabled: true
      v2:

// release notes for more information.
// ControllerRevision implements an immutable snapshot of state data. Clients
// are responsible for serializing and deserializing the objects that contain
// their internal state.
// Once a ControllerRevision has been successfully created, it can not be updated.
// The API Server will fail validation of all requests that attempt to mutate

                        "description": "Manage items. So _fancy_ they have their own docs.",
                        "externalDocs": {

    be used to make canonical URLs for the cache that omit insignificant query parameters or other
    irrelevant data.

    This feature may be used with `POST` requests to cache their responses. In such cases the
    request body is not used to determine the cache key, so you must manually add cache-relevant
    data to the override URL. For example, you could add a `request-body-sha256` query parameter so

        if (rawType.isAssignableFrom(String.class)) {
            return text; // compatible type => no conversion needed
        }

        // use temporary Key as quick way to auto-box primitive types into their equivalent object types
        final TypeLiteral<?> boxedType =
                rawType.isPrimitive() ? Key.get(rawType).getTypeLiteral() : toType;
