Web API Design - Crafting Interfaces that Developers Love This e-book is a collection of design practices that we have developed in collaboration with some of the leading API teams around the world, as they craft their API strategy through a design workshop that we provide at Apigee. One of the sources for our design thinking is REST. Because REST is an architectural style and not a strict standard, it allows for a lot of flexibly. Because of that flexibility and freedom of structure, there is also a big appetite for design best practices.
We call our point of view in API design ?pragmatic REST?, because it places the success of the developer over and above any other design principle. The developer is the customer for the Web API. The success of an API design is measured by how quickly developers can get up to speed and start enjoying success using your API.
