Works exactly the same in Sails. You’d probably want to create a new (sails) Service, and then you can use it in your controllers.
If its just to send the occasional SMS or whatever, a service is easy and fast. If you’re going to use a lot of the twilio API, you could potentially write a Sails/Waterline adapter, and then treat an SMS like a standard Model.. so you could use the blueprints and cool stuff like that.
