How to Build Engaging Apps With Social Networking APIs

Very few people these days are unfamiliar with leading social networking platforms such as Facebook, Twitter, Pinterest and LinkedIn. Many developers and other tech industry professionals use social networking sites and applications on a regular, often daily, basis. However, some of those professionals may not be aware of the types of APIs and tools available from the leading social networking platforms. This article looks at some of the APIs, SDKs and tools available from six of the leading social networking companies, as well as a variety of applications and websites that leverage the features of these platforms.


The Facebook Developer Center provides SDKs, APIs and other tools that developers can use to integrate Facebook functionality with websites and applications such as Facebook login, sharing buttons, payments and social graph. In April 2013, Facebook acquired Parse, a leading Back-end-as-a-service provider offering SDKs for a variety of platforms such as iOS, Android, Windows Phone, JavaScript, Unity and REST. Developers can use the Parse service to quickly and easily create Internet-enabled web, mobile and desktop applications. Facebook has had a pretty busy 2014 so far, releasing Conceal Encryption and data Authentication Java APIs, announcing the release of an open source version of the Hack programming language, and unveiling new APIs that are part of Facebook's Public Content Solutions program. Below are a few examples of applications that have incorporated Facebook Platform features and functionality using Facebook APIs, SDKs and/or tools.
