                      In Detail

                      Have you ever wanted to integrate phone features into a project you were working on? Maybe you wanted to send SMS messages to your customers about the latest sales? Maybe you want to set up a company directory with voice mail? Or maybe you want to add two factor authentication to your web sites to verify your users? Since Twilio was launched in 2007, developers have had a way to do these tasks. The power of Twilio’s API is huge and lets you add any type of phone solution to your web site from 2-factor authentication for verifying your users, to setting up a company directory and a voice mail system. The possibilities are endless.

                      "Twilio Cookbook" is your Swiss army knife for Twilio development, providing you with a number of clear step-by-step exercises. It helps you take advantage of the real power of the Twilio API, and gives you a good grounding in using it in your websites. This book looks at the Twilio API, and breaks down the mystery and confusion that surrounds adding telephone functionality to your websites. As you go through the recipes, you will learn how to take advantage of the Twilio API quickly and painlessly.

                      You will learn how to build your own IVR system, company directory, and voicemail box, and also how to set up a 2-factor authentication system to verify users, track orders via SMS, send surveys using SMS, allow users to buy phone numbers, set up and delete sub-accounts, and check to see if a human is answering a phone call. We will also combine Twilio with other APIs to build a handy local search system such as a local business search, movie listings search, and web search. If you want to take advantage of using Twilio’s API to add telephone functionality to your websites, then this book is for you.

                      "Twilio Cookbook' will leave you with a black belt in Twilio development and enable you to integrate the API into your websites.


                      This book is a practical, hands-on guide that provides the reader with a number of clear, step-by-step exercises.

                      Who this book is for

                      This book is great for developers who already have knowledge of PHP and MySQL and who want to learn about integrating Twilio’s API into their websites for telephone solutions.
