The hands-on, step-by-step guide to building Twitter apps and integrating Twitter into existing sites, services, and applications #xA0; #xA0; Shows what can be done with the Twitter API - including non-traditional examples By the creator of the popular Twitterfilter app Covers API basics, REST, calls, replies, components, displays, classes, errors, credentials, search, downtime, etiquette, and more Quick, easy examples deliver results fast, and handy reference sections help programmers for years to come #xA0; Finally there's a practical guide to developing new Twitter applications and integrating Twitter into existing sites and applications. One step at a time, this book teaches all facets of Twitter programming, from the absolute basics to rich, non-traditional application development utilizing multiple API calls. Top Twitter developer Christopher Peri demonstrates what the Twitter API can do, introduces each leading type of Twitter application, and discusses the issues developers face in using the Twitter API. Peri shows how to set up the Twitter API environment; make API calls and parse responses; work with components; create displays; build application frameworks; handle error messages and downtime; pass credentials to Twitter; create clients; send messages; use Twitter search; and more. Along the way, Peri provides innovative solutions to Twitter programming problems, helping developers overcome API limitations they'd otherwise struggle with. Peri concludes by previewing the future of Twitter and its API; demonstrating innovative example applications and mashup services; and explaining the crucial "etiquette" of Twitter development. Throughout, each lesson builds on everything that's come before, helping readers learn core techniques from the ground up. Concise, easy-to-reuse code samples help developers get started fast, and detailed Twitter API reference sections support them for years to come.

Dr. Christopher Peri received his Doctorate from the University of California, Berkeley, in Architecture. His focus was on Collaboration in Virtual Environments delving into methods that facilitate designers and engineers to improve communication over remote networks.

He started playing with the Twitter API very early in the API release, creating his own Twitter client called TwittFilter, which is geared more to the occasional user then someone who uses Twitter all the time. As time went on, he added more and more features and functions for his own personal use, until one day he realized he had a fairly sophisticated application and opened it up to the general public to use. He learned quite a bit about the Twitter API the hard way—by simply coding things up and seeing what happens. Although TwittFilter is still a personal project, he has already created a number of private Twitter applications, robots, and smaller projects like NewsSnacker.com, which is open to the public.
