How to get User Info from historyDetails

We are using process instance variables to track user input from a UI application which uses flowable engine in backend. The historyDetails give the timestamp and value change, is there a way to get the information of user who did the variableUpdate.

I assume you’re talking about a variable change? If so, no, that information is not stored right now. However, typically there’s a user task related to the variable change and the user id is save there (i.e. the assignee).

Thank you for the input! Yes, I am referring to variable change. So audit logs will give the variable changes only, and not the user who did it.
