- Used to store data dynamically
- Used pass the data within and between the projects from one workflow to another.

You can create arguments from :
- Arguments Panel
- Properties Panel

- In: This direction means that the argument can only be used within the given workflow. It’s used to enable the calling workflow provide a parameter INWARDS to the current workflow. Naming Convention should be: in_<Argument Name>(Ex: in_Config)
- Out: This direction means that the argument can be used to pass data outside the given workflow. In other words, if you want to return some value OUTWARDS to the calling workflow, use this type of argument. Naming Convention should be: out_<Argument Name>(Ex: Out_Item)
- In/Out: This direction means that the argument can be used within and outside the given workflow.An IN/OUT type of argument is used when you want to send a variable as parameter and want the modified value of the same variable as return value. Naming Convention should be: io_<Argument Name>(Ex: io_Name)
- Property: This direction is not in use currently.
