Appointments+ integration with SMS


I am trying to integrate SMS for reminders, confirmations, notifications etc for appointments+

I have found a few hooks but they are not quite working for me.

Here are some hooks that i have tried using:


When i update the status of the appointments from backend (as admin) I dont get hooked into the system.

Please let me know what i am doing wrong

P.S: I have enabled Email confirmation in the settings.
