PDF Delete Watermark Tool Guide

Note：Before learning how to use different functions, we recommend that read the Request Workflow to know a basic PDF processing process. When using different functions, you can set their own special parameters when uploading files. Other basic steps are consistent.

Java Example:

Replace apiKey with the publicKey obtained from the dashboard, file with the file you want to convert, and language with your preferred interface error prompt language type.

import java.io.*;
import okhttp3.*;
public class main {
  public static void main(String []args) throws IOException{
    OkHttpClient client = new OkHttpClient().newBuilder()
      .build();
    MediaType mediaType = MediaType.parse("text/plain");
    RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
      .addFormDataPart("file","{{file}}",
 RequestBody.create(MediaType.parse("application/octet-stream"),
                                          new File("<file>")))
      .addFormDataPart("language","{{language}}")
      .addFormDataPart("password","")
      .build();
    Request request = new Request.Builder()
      .url("https://api-server.compdf.com/server/v1/process/pdf/delWatermark")
      .method("POST", body)
      .addHeader("x-api-key", "{{apiKey}}")
      .build();
    Response response = client.newCall(request).execute();
  }
}
