The Quickstarts are short simple guides intended to help you get started using Twilio's voice and SMS APIs.
The Hello Monkey Quickstart provides an introduction to the Twilio Markup Language (TwiML). The demo walks though the process of building a system to handle incoming calls that greets callers by name, plays an audio file, connects the call to another phone number, and lets callers leave an audio recording.
The Twilio REST API Quickstart demonstrates how to build an application that initiates an outgoing phone call and gets a list of previous calls using the Twilio REST API.
The Twilio SMS Quickstart demonstrates how to build an application that sends and receives SMS messages using Twilio Markup Language (TwiML) and the Twilio REST API.
