After submission, you can redirect users to a URL that contains this ID.Paste the URL below in the Settings – Thank you Page – Redirect to a web page box and make the indicated adjustments.
a) http://www.yoursite.com/file.php – Replace this with your custom page.
b) yourrefid – Here, you can use any variable you want (ABC, Order Number, anything). The variable can be different from the one you have put in the Reference ID box, in Notifications.
