Tonight I started working on the RESTful API for PancakeApp - an invoicing system built in CodeIgniter - when I remembered how many people have been asking for help using REST_Controller. I wrote up an article on NetTuts last year "Working with RESTful Services in CodeIgniter" hoping that would cover the majority of questions but with new features like API Keys, Limiting and Logging being added I thought a quick run-through was in order. This video covers the basic implementation, HTTP Basic/Digest authentication, format switching and goes onto the new API Key and logging features.
