It can be used in the Form Builder, List Builder, and UI Builder to dynamically retrieve and display the values of runtime variables. Beyond these builders, Hash Variables are also utilized in configuring properties for supported plugins, naming activities within the Process Builder, and specifying external form URLs when mapping activities to external forms.
