Modify A Value - aareano/ifshop-wiki GitHub Wiki
The "modify a value" action allows you to apply updates to nearly every field that can be updated. This includes product titles, variant prices, tax policies, customer details, order emails, you name it! As with the filters, there is a custom configuration option for this action which gives you the incredible control to enact any update anywhere in your shop based on any data available.
As a brief word of warning, this action can also cause infinite loops. These are not to be trifled with as they can use up your subscription action credits very quickly. Read this article on what exactly infinite loops are and how to avoid them.
