Twilio refers to a set of web services, APIs and tools provided by the Twilio company. These are used to send and receive text/picture messages, make and receive phone calls, and embed VoIP calling into web and native mobile applications. They provided many helper libraries, available for various server-side programming environments like Node.js, PHP, .NET, Java, Ruby, Python, Apex etc.

In this blog, we will use the Twilio node module to implement inbound and outbound voice calls in Node.js.

In an earlier blog, we have discussed about Token based authentication and authorization and how it is being implemented in one of our projects. Over these past few months, we’ve made changes to our approach.
Read on to find out what enhancements we have made and why.

It has become common for any social mobile or web app to support notifications and track user activities within that application.

We’ve been working extensively with Node.JS and Express for the past 8 months and have picked a few components that allow us to work efficiently and manage our project better. In this blog we will be discussing how to setup a Node.JS project with,

What is token based authentication ? 

At a very basic level, token based authentication works as follows –
