One of the greatest challenges of building an API is building one that will last. This is especially true for Web APIs, where you are creating both a contract between you and your users and a programming contract between your server and the client.
While the function of an API may be fairly straightforward and simple, the process of choosing which type to build, understanding why that type of API is best for your application, and then designing it to work effectively is key to giving your API a long life and making sure that it’s used by developers.
There are many types of APIs. For example, you may have heard of Java APIs, or interfaces within classes that let objects talk to each other in the Java programming language. Along with program-centric APIs, there are also Web APIs such as the Simple Object Access Protocol (SOAP), Remote Procedure Call (RPC), and perhaps the most popular—at least in name— Representational State Transfer (REST).
