To use the <Link to={useBaseUrl("/docs/features/plugins/network")}>Network plugin</Link>, you need to add the plugin to your Flipper client instance.

## Android

The network plugin is shipped as a separate Maven artifact, as follows:

```groovy
dependencies {
  debugImplementation 'com.facebook.flipper:flipper-network-plugin:0.220.0'
}
```

Once added to your dependencies, you can instantiate the plugin and add it to the client:

```java
import com.facebook.flipper.plugins.network.NetworkFlipperPlugin;

NetworkFlipperPlugin networkFlipperPlugin = new NetworkFlipperPlugin();
new NetworkingModule.CustomClientBuilder() {
    @Override
    public void apply(OkHttpClient.Builder builder) {
        builder.addNetworkInterceptor(new FlipperOkhttpInterceptor(networkFlipperPlugin));
    }
});
client.addPlugin(networkFlipperPlugin);
```

### OkHttp Integration

If you are using the popular OkHttp library, you can use the Interceptors system to automatically hook into your existing stack, as shown in the following snippet:

```java
import com.facebook.flipper.plugins.network.FlipperOkhttpInterceptor;

new OkHttpClient.Builder()
    .addNetworkInterceptor(new FlipperOkhttpInterceptor(networkFlipperPlugin))
    .build();
```

As interceptors can modify the request and response, add the Flipper interceptor after all others to get an accurate view of the network traffic.

### Protobuf / Retrofit Integration

If you are using Retrofit with Protobuf request or response types, you can setup automatic decoding so that the network inspector can display a human readable payload. First you must add the separate dependency:

```groovy
dependencies {
  debugImplementation 'com.facebook.flipper:flipper-retrofit2-protobuf-plugin:0.91.2'
}
```

Then call `SendProtobufToFlipperFromRetrofit` for each service class:

```kotlin
import com.facebook.flipper.plugins.retrofit2protobuf.SendProtobufToFlipperFromRetrofit

SendProtobufToFlipperFromRetrofit("https://baseurl.com/", MyApiService::class.java)
```

## iOS

To enable network inspection, add the following pod to your Podfile:

```ruby
pod 'FlipperKit/SKIOSNetworkPlugin', '~>' + flipperkit_version
```

Initialize the plugin in the following way by updating AppDelegate.m:

<Tabs defaultValue="objc" values={[{ label: 'ObjC', value: 'objc'}, { label: 'Swift', value: 'swift'}]}>
<TabItem value="objc">

```objc
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>

[[FlipperClient sharedClient] addPlugin: [[FlipperKitNetworkPlugin alloc] initWithNetworkAdapter:[SKIOSNetworkAdapter new]]];
```

</TabItem>
<TabItem value="swift">

```swift
import FlipperKit

client?.add(FlipperKitNetworkPlugin(networkAdapter: SKIOSNetworkAdapter()))
```

</TabItem>
</Tabs>
