In addition to simple PDF format conversion, we provide more parameter choices for advanced functions. You can set the parameters you want in the process of upload file . Below you can learn about the optional parameters of various functions.

Simple PDF Conversion Tool Guides

Note：Before learning how to use advanced functions, we recommend that you read the Request workflow to understand a basic PDF processing process.

Java Example

1. Authentication

   You need to replace {{public_key}} and {{secret_key}} with accessToken in the publicKey and secretKey authentication getback values you get from the console.

   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 = RequestBody.create(mediaType, "{\n    \"publicKey\": \"{{public_key}}\",\n    \"secretKey\": \"{{secret_key}}\"\n}");
       Request request = new Request.Builder()
         .url("https://api-server.compdf.com/server/v1/oauth/token")
         .method("POST", body)
         .build();
       Response response = client.newCall(request).execute();
     }
   }
   

2. Create Task

   You need to replace {{accessToken}} with the accessToken obtained from the previous step, and {{executeTypeUrl}} with the conversion type you need. You can get the function you want to use in the Tools, and get the taskId in the return value after success.

   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 = RequestBody.create(mediaType, "");
       Request request = new Request.Builder()
         .url("https://api-server.compdf.com/server/v1/task/{{executeTypeUrl}}")
         .method("GET", body)
         .addHeader("Authorization", "Bearer {{accessToken}}")
         .build();
       Response response = client.newCall(request).execute();
     }
   }
   

3. Upload Files

   Replace {{file}} with the file you want to convert, {{taskId}} with the taskId obtained in the previous step, and {{accessToken}} with the accessToken obtained in the first step.

   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("taskId","{{taskId}}")
         // your file hava password
         //.addFormDataPart("password","{{password}}")
         .addFormDataPart("parameter","<parameter>")
         .build();
       Request request = new Request.Builder()
         .url("https://api-server.compdf.com/server/v1/file/upload")
         .method("POST", body)
         .addHeader("Authorization", "Bearer {{accessToken}}")
         .build();
       Response response = client.newCall(request).execute();
     }
   }
   

4. Process Files

   Replace {{taskId}} with the taskId you obtained from the Create task, and {{accessToken}} with the accessToken obtained in the first step.

   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 = RequestBody.create(mediaType, "");
      Request request = new Request.Builder()
        .url("https://api-server.compdf.com/server/v1/execute/start?taskId={{taskId}}")
        .method("GET", body)
        .addHeader("Authorization", "Bearer {{accessToken}}")
        .build();
      Response response = client.newCall(request).execute();
    }
   }
   

5. Get Task Information

   Replace {{taskId}} with you from Create the task obtained in the taskId, {{access_token}} replaced by access_token obtained in the first step .

   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 = RequestBody.create(mediaType, "");
       Request request = new Request.Builder()
         .url("https://api-server.compdf.com/server/v1/task/taskInfo?taskId={{taskId}}")
         .method("GET", body)
         .addHeader("Authorization", "Bearer {{accessToken}}")
         .build();
       Response response = client.newCall(request).execute();
     }
   }
