Has a client ever asked you to make the site work with a 3rd party service's API and you couldn't find a useful Drupal module? Or has a mobile app developer ask you to make parts of the site RESTful? Nowadays, with Drupal moving away from a simple CMS/Framework role into a more SAAS-like (Software As A Service) approach, REST is the protocol of choice and a basic understanding of the standards/workflow will gain importance in time as a Drupal developer.
In this session, I would like to introduce to you on how to interact with 3rd party REST services and what tools/libraries are useful during development. Furthermore, I will talk about my experiences using Drupal 7 as a RESTful service and compare that to the shiny new Drupal 8 implementation.
This session caters mainly towards custom module developers. I will try not to make this too code heavy, but it's hard to address this topic without any code samples.
