Hi @Celiane_Brasil_Rocha and welcome to the forum,
It’s not possible with the Events endpoint specifically, but you could get some of that data by reading the Stories objects from the tasks in the project. That is, loop through each task in the project, and for each task, loop through all of its stories. That may or may not get you the data you need - but it might!
The only two caveats to make about stories:
(1) They can be deleted by users.
(2) They are not necessarily a complete audit trail of changes due to a process Asana calls story consolidation.
