Solution:
I was able to solve this issue with the code below:
<?php
wp_nonce_field( 'update-order-review', 'update_order_review_nonce', false, true );
?>
The code will generate a code with update_order_review_nonce as the name property of the input element.
Simple explanation:
The first parameter is a unique name of the action that woocommerce plugin uses. Second parameter is the name of the element. Third parameter ignores the referrer field so I can place and use the key on the page that I prefer.
The code above can be found on: \woocommerce\includes\class-wc-frontend scripts.php and just find the line ‘update_order_review_nonce' => wp_create_nonce( 'update-order-review' ),
You can use jquery to get the value or whatever will be your purpose.
