In the last post, we saw how every company is building an API for its services. Other companies can then access the services in their own apps. This builds an ecosystem around the company’s services and the company builds both its reputation and its business. But you will see that companies are now building ‘REST’ APIs. REST stands for REpresentational State Tranformation. It is a clunky, overly technical term that even those from technology fail to understand, let alone hope to build an API which is ‘REST-compliant’. In this post, I will completely dejargonise the term and explain to you what it means by taking a very common activity: Reading a book, inserting bookmarks and marking with a highlighter.
