In this guide, we'll show you how to convert raw HTML to PDF using Java and the OkHTTP library.

Converting raw HTML content to PDF is useful when you have HTML content that isn't hosted on a web server.

```java
import okhttp3.*;
import java.io.IOException;

// You can get an API key at https://pdfshift.io
String apiKey = "sk_xxxxxxxxxxxx";

OkHttpClient client = new OkHttpClient();

RequestBody body = RequestBody.create(
    "{\n" +
    "  \"source\": \"<html><body><h1>Hello World</h1></body></html>\"\n" +
    "}", MediaType.parse("application/json"));

Request request = new Request.Builder()
    .url("https://api.pdfshift.io/v3/convert/pdf")
    .addHeader("X-API-Key", apiKey)
    .post(body)
    .build();

try (Response response = client.newCall(request).execute()) {
    
    // Handle errors:
    if (!response.isSuccessful()) {
        throw new IOException("Request failed with status code " + response.code());
    }
    
    ResponseBody responseBody = response.body();
    if (responseBody != null) {
        java.nio.file.Files.write(
            java.nio.file.Paths.get("result.pdf"), 
            responseBody.bytes()
        );
    }
    
    System.out.println("The PDF document was generated and saved to result.pdf");
}
```

This allows you to convert HTML content directly to PDF without needing a URL.
