Set checkout data in Order Desk when new Squarespace Forms forms are submitted

This integration is a great way to add new data to orders that have already been imported into Order Desk. If a customer fills out a form on Squarespace Forms, their order in Order Desk can be updated automatically with checkout data that designates that a form has been filled out. From there, rules in Order Desk can target that checkout data to take further action on the order.
