class PDFFillSimpleExample {

  public static void main(String[] args) {
    ObjectMapper mapper = new ObjectMapper();

    // JSON object
    ObjectNode dataObj = mapper.createObjectNode();
    dataObj.put("shortText", "HELLO");
    dataObj.put("date", "2022-07-08");

    ObjectNode payload = mapper.createObjectNode();
    payload.put("title", "My PDF Title");
    payload.put("fontSize", 10);
    payload.put("textColor", "#333333");
    payload.putPOJO("data", dataObj);

    String payloadStr = mapper.writeValueAsString(payload);
    String pdfTemplateEid = "B5Loz3C7GVortDmn4p2P";

    // your Anvil API_KEY
    RestClient client = new RestClient(API_KEY);
    HttpResponse<byte[]> response = client.fillPdf(pdfTemplateEid, payloadStr);

    Files.write(Paths.get("output/fill-output.pdf"), response.body());
    System.out.println("Fill PDF finished");
