This episode story is simple.
If we receive response that is list type, we can use <code>flatMapIterable</code> operator(finally return type is Flux). Sometimes, I found the <code>Mono&lt;List&lt;T&gt;&gt;</code> type. 
<pre><code class="lang-java">public Flux&lt;String&gt; getData() {
 return this.webClient.get()
 .uri(uriBuilder -&gt; uriBuilder
 .path("/data")
 .build()
 )
 .retrieve()
 .bodyToMono(DataApiResponse.class)
 .flatMapIterable(DataApiResponse::getContent);
}

@Value
public class DataApiResponse {
 List&lt;String&gt; content;
}
</code></pre>
Afterwards, If we use <code>getData()</code> method in the business layer, we can change Flux to Stream using <code>toStream()</code> operator and then change Stream to List using <code>collect</code> operator again.
<pre><code class="lang-java">List&lt;String&gt; data = apiClient.getData()
 .toStream()
 .collect(toUnmodifiableList());
</code></pre>

This episode story is simple.
If we receive response that is list type, we can use `flatMapIterable` operator(finally return type is Flux). Sometimes, I found the `Mono<List<T>>` type. 
```java
public Flux<String> getData() {
	return this.webClient.get()
		.uri(uriBuilder -> uriBuilder
			.path("/data")
			.build()
		)
		.retrieve()
		.bodyToMono(DataApiResponse.class)
		.flatMapIterable(DataApiResponse::getContent);
}

@Value
public class DataApiResponse {
	List<String> content;
}
```

Afterwards, If we use `getData()` method in the business layer, we can change Flux to Stream using `toStream()` operator and then change Stream to List using `collect` operator again.
```java
List<String> data = apiClient.getData()
	.toStream()
	.collect(toUnmodifiableList());
```
