### Application Interceptors

Interceptors are registered as either _application_ or _network_ interceptors. We'll use the `LoggingInterceptor` defined above to show the difference.

Register an _application_ interceptor by calling `addInterceptor()` on `OkHttpClient.Builder`:

```java
OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(new LoggingInterceptor())

            return maxBandwidthChannel != null ? maxBandwidthChannel : channels.iterator().next();
        }

        if (isMetadataOperation(message)) {
            // For metadata operations, prefer low-latency channels
            return selectLeastLoaded(channels);
        }

        // Default to weighted random for general operations
        return selectWeightedRandom(channels);
    }

### Check the docs { #check-the-docs }

Because the available values for the *path parameter* are predefined, the interactive docs can show them nicely:

### Working with Python *enumerations* { #working-with-python-enumerations }

The value of the *path parameter* will be an *enumeration member*.

Dieses *Pfadoperation*-spezifische OpenAPI-Schema wird normalerweise automatisch von **FastAPI** generiert, Sie können es aber auch erweitern.

/// tip | Tipp

Dies ist ein Low-Level Erweiterungspunkt.

Wenn Sie nur zusätzliche Responses deklarieren müssen, können Sie dies bequemer mit [Zusätzliche Responses in OpenAPI](additional-responses.md){.internal-link target=_blank} tun.
