RESTful APIs
Resource-oriented API design.
RESTful APIs is taught here in 3 lessons, running from Resource modelling and methods through to Versioning and error shapes. Each lesson takes one topic, shows the working code, and links onward to the next, so the course can be read straight through in order.
