How to get name of the User who accepted the Story through JIRA API ?

[Thrivikrama Madiraju]

I am trying to get User Story details through JIRA api.
One information we couldn't find is how to get the Name of the user who accepted the Story ?

Best way to figure out who did what in the ticket is to check the history.

I'm not sure if you can use Groovy, but this is how I would do it using ScriptRunner.

if(event?.getChangeLog()?.getRelated('ChildChangeItem').find {it.status == "Accepted"}){
//Get the username
}
