This Magento extension integrated enables the automatic sending of various notification SMS via Twilio.
Right now it supports sending a notification to the store owner when a new order is placed and a notification to a customer once a new shipment has been created for them. Easily extendable with new functionality (pull requests welcome!).
Install using colinmollenhour/modman.
Most of my repositories posted here are projects created for customization requests for clients, so they probably aren't very well documented and the code isn't always 100% flexible. If you have a question or are confused about how something is supposed to work, feel free to get in touch and I'll try and help: [email protected].
