We are using Prefect cloud and We want to enable task level SLA. Whenever the task in the flow is delayed, We want to get notification. is that possible?

Tasks don’t have a concept of delated so it would have to be on the Flow level. Do you need a task to run at a specific time? This can be done with a state handler maybe. Do something like:

def myhandler(task, old_state, new_state):
    if new_state.is_running():
        # put python logic to check lateness here
        if late:
             send_some_notification
