Is it possible to receive HTTP notification when a job is cancelled?

When scheduling a report using the BI Publisher interface, it is possible to send a notification via HTTP when the report is canceled? The web services API has a method called scheduleService.cancelSchedule which takes parameters job instance ID + username/pw combination. When calling this method on a long running job, it responds back with "cancelScheduleReturn = 'G' ". 

However, my HTTP server does not receive any message from BIP. I've attached a screenshot below of the notification settings for my HTTP endpoint. I receive a notification on all of the following events: successful job, failed job, job with errors. But not for a canceled job.
