Get business key in task list

Is there how to retrieve the business key in task list? For example, it could be returned in REST API GET \task. Today it is only returned the processInstanceId and I have to make another fetch to the API in order to get the businessKey. I beleive this can have a bad performance when the task list is very long.

Hi @erikasegatto,

At the moment, retrieving a business key from a list of tasks is not possible. A ticket already exists for this: and you can follow its status. However, I am unsure if it will be implemented any time soon.
