@erdemedeiros is this one for admin as well -> POST /v1/tasks/${id}/claim

[salaboy]

@erdemedeiros I don't think that we need this one: POST admin/v1/tasks/${id}/claim

we should do that via task update sending the assignee that the admin wants to set. That should work, but we need to check the events. I would expect a TaskUpdated Event only..

[salaboy]

@erdemedeiros and this one: DELETE admin/v1/tasks/${id} should fail if the task belong to a process.. it should say something like.. delete the process instance and the task will be deleted for you.
