Set Variable Value

Set Variable Value

This action allows you to store a value inside a variable or a custom field. This is very useful when you want to collect data from your users.

The Different Types of Value

Once you click on the set custom field action, you’ll be able to choose which custom field needs some to update in terms of value.

You can either put in some data or even another custom field as a value as well.

Should you need to create a new custom field, just type in the name and choose the type of custom field you’d like to create.
