In this tutorial, we will learn how to generate Word or PDF documents using the Documentero API service in Java. Documentero is an API service that allows you to generate documents based on templates and data provided.

Prerequisites

Before we begin, make sure you have the following:

  • Java Development Kit (JDK) installed on your machine
  • Documentero API access and your API secret key

Step 1: Setting up the Project

Let’s start by setting up a new Java project. Open your preferred Integrated Development Environment (IDE) and follow these steps:

  1. Create a new Java project and name it as “DocumenteroDemo”.

  2. Create a new class named “DocumentGenerator” and open it.

Step 2: Making a POST Request to Documentero API

Next, we’ll write the code to make a POST request to the Documentero API service and generate a document.

In the “DocumentGenerator” class, let’s start by importing the required libraries and defining the API endpoint:

import okhttp3.*;
import org.json.JSONObject;
import java.io.IOException;

public class DocumentGenerator {
    private static final String DOCUMENTERO_ENDPOINT = "https://app.documentero.com/api";
}

Now, let’s define a method to generate the document:

public static void generateDocument() {
    OkHttpClient client = new OkHttpClient();

    MediaType mediaType = MediaType.parse("application/json");

    JSONObject requestBody = new JSONObject();
    requestBody.put("document", "Pt04DVNbifqY4inserI2"); // Replace with your template identifier
    requestBody.put("apiKey", "YOUR_API_KEY"); // Replace with your API secret key
    requestBody.put("format", "docx"); // Set the desired format: 'docx' for Word or 'pdf' for PDF

    JSONObject data = new JSONObject();
    data.put("field", "fieldvalue"); // Replace with the data you want to pass to the document generation
    requestBody.put("data", data);

    RequestBody body = RequestBody.create(mediaType, requestBody.toString());

    Request request = new Request.Builder()
            .url(DOCUMENTERO_ENDPOINT)
            .post(body)
            .addHeader("Content-Type", "application/json")
            .build();

    try {
        Response response = client.newCall(request).execute();
        if (response.isSuccessful()) {
            JSONObject responseBody = new JSONObject(response.body().string());
            int status = responseBody.getInt("status");
            String message = responseBody.getString("message");
            String downloadLink = responseBody.getString("data");

            if (status == 200) {
                System.out.println("Document Generated Successfully");
                System.out.println("Download Link: " + downloadLink);
            } else {
                System.err.println("Document Generation Failed: " + message);
            }
        } else {
            System.err.println("Unexpected response from Documentero API");
        }
    } catch (IOException e) {
        System.err.println("An error occurred: " + e.getMessage());
    }
}

Make sure to replace "Pt04DVNbifqY4inserI2" with the actual template identifier provided by Documentero, and "YOUR_API_KEY" with your API secret key obtained from Documentero.

Step 3: Running the Code

Save the changes to the “DocumentGenerator” class. Now, let’s write a main method to execute the code and generate the document.

public static void main(String[] args) {
    generateDocument();
}

Step 4: Running the Code

Save the changes to the “DocumentGenerator” class. Now, let’s write a main method to execute the code and generate the document.
