How to create optional argument while using Invoke code activity

how to create optional argument while using Invoke code activity
as for example even if i do not supply value for those particular arguments then also activity should work

Is it possible ?

You can Just Keep them as it is without Providing any Value.

But make sure that you handle the exceptions properly inside the invoked workflow.

E.g. - I have an Input Arguement : Name as string.

Inside the invoked workflow before using the Name arguement, I would check if the String value is Not Null or Empty or Blank.

This way , If I Get the Name Value - it works,
If not - It does Nothing .

Else,

You can try by providing Default Values in the arguements Pane.
