The late 00s and early 2010s saw an explosion in the availability of HTTP APIs, driven by the rise of mobile apps. This explosion led to rich API ecosystems of varying quality and consistency across the web.

In this session we'll cover how to design RESTful APIs that are comprehensible to humans, while being friendly to the machines that have to integrate with them, looking back on 15 years of building APIs that were used by everyone.

We'll cover how to design resources, how to respect HTTP, ensuring that your APIs are consistent and efficient, the perils of versioning and the joys of hypermedia. This talk is for anyone that wants to make their APIs a pleasure to use.
