I am setting up an event using CiviEvent.
People can register and have to transfer the event fee.
What do I need to to that people get a one time notification if the payment is received (manual status change to "transfer received") or if their registration is canceled (for example to modify it).
I am aware of the automatic reminders but I did not found how to configure them that the message is sent just at the day of the status change and only at that day.
I am using CiviCRM 5.2.0 on Wordpress 4.9.6.
