Estou tentando enviar os dados do JSON através do Java, só que não consigo enviar qnd tem mais de um objeto nos campos, como o de orders, por exemplo. Mas qnd eu envio para uma categoria de campo simples ele funciona normal, alguem sabe dizer como eu consigo fazer com que os dados cheguem nessas categorias onde o JSON tem vários objetos?

o meu código está assim:

 public static void main(String[] args) throws JSONException {
        // Setup client

        OAuthConfig config = new OAuthConfig("https://olinkoriginalestaaqui.com.br",
                "chave ck",
                "chave cs");    // No código original elas já estão colocadas corretamente

        WooCommerce wooCommerce;
        wooCommerce = new WooCommerceAPI(config, ApiVersionType.V3);



        //Dizendo os campos e dando os valores

       Map <String, Object> orderInfo = new HashMap<>();
      orderInfo.put("payment_method", "bacs");
      orderInfo.put("payment_method_title", "Direct Bank Transfer");
      orderInfo.put("first_name", "Joe");
      orderInfo.put("last_name", "Doe");
      orderInfo.put("address_1", "969 Market");
      orderInfo.put("address_2", "");
      orderInfo.put("city", "San Francisco");
      orderInfo.put("state", "CA");
      orderInfo.put("postcode", "94103");
      orderInfo.put("country", "US");
      orderInfo.put("email", "john.doe@example.com");
      orderInfo.put("phone", "(555) 555-5555");
      orderInfo.put("first_name", "Joe");
      orderInfo.put("last_name", "Doe");
      orderInfo.put("address_1", "969 Market");
      orderInfo.put(  "address_2", "");
      orderInfo.put("city", "San Francisco");
      orderInfo.put("state", "CA");
      orderInfo.put("postcode", "94103");
      orderInfo.put("country", "US");


        //mapeando os pedidos
        Map order = wooCommerce.create(EndpointBaseType.ORDERS.getValue(),orderInfo);


        System.out.println(order.get("id"));


        Map <String,String> params = new HashMap<>();
        params.put("per_page", "100");
        params.put("offset", "0");
        List products = wooCommerce.getAll(EndpointBaseType.ORDERS.getValue(), params);

        System.out.println(products.size());

    }

e o que retorna é o seguinte JSON:
