There is a lot of talk these days about tapping into the resources available through external APIs (Twitter, Facebook, Flickr, etc). Much of the functionality needed to interact with APIs is already included in the core through the HTTP class. In this session you will learn the concepts behind pulling data from an external API, sending data to an external API, how to utilize WordPress caching to increase speed and functionality, etc.
Here are the slides from the presentation: Interacting with External APIs – wcmaui 2015
