See the Unique Code field in the order confirmation email

Hi @lucafurlan!

In this case, you can add a custom field (like the Unique code field) of an order to the emails with the following guide:

I hope this helps!

Good morning,
We tried to use the code to modify the template but without success as the S.D.I field still does not appear in the order summary email.
Can you give us further support?
Thank you.

Hi,

I understand you would like to add an extra field to the order emails.

You can do it using custom code, please note, per the forum policies, custom code is not supported here, however, I’ve found this article on the web that might help you out (You will need to adapt the code according to your needs):
