I have created module to get order_id to get some custom information from database.


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
<event name="email_order_set_template_vars_before">
    <observer name="add_custom_variable_to_Order"


namespace Customedit\GetOrder\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\Request\DataPersistorInterface;
use Magento\Framework\App\ObjectManager;
class ObserverforAddCustomVariable implements ObserverInterface

  public function __construct()
  public function execute(\Magento\Framework\Event\Observer $observer)
    $transport = $observer->getTransport();
    $order = $transport->getOrder()->getId();
    $transport['Get_OrderId'] = $order;

Now, I want to check that I can get orderId with

{{var Get_OrderId}}

it returned nothing.

Did I use wrong method or did something wrong?

If I can't get order_id. Can I get increment_id instead?

You are using correct event for process email templates for new order

See some notes and example in https://magento.stackexchange.com/a/358613/91782

If you want to operate order data better to extend and use order_data array.

The Order ID is already present in template and you can use following to render it in template

{{var order_id}}
