Where can I find the parameter for Event ID or Problem ID

In one of my notification rules, I am using notification method ASCII Email.
Where I need to use the event-id or problem-id.
I have searched through the official documentations, but could not find a suitable parameter that can be used inside the email template of notification rule.
Below is my sample email body template.

Service:  $SERVICEDESC$
Event:    $EVENT_TXT$
Output:   $SERVICEOUTPUT$

Event ID: $EVENT_ID$
