Hello everyone! How is it going?
A few months back alot of people were asking if SMS integration can be done with the WPMU appointments+ plugin. I am happy to announce that we have made a plugin that extends the appointments+ plugin to integrate SMS notifications.
We currently have it working with Twilio and Clockwork SMS gateways.
These SMS notifications work if email notifications are enabled (as the plugin has hooks for email only).
Anyone who wants it please visit (my very recent and under development)website :
