WordPress, one of the most popular CMSs on the internet needed to come into the era of the mobile app. Many companies are choosing to develop native apps as well as or even instead of having a dedicated website – so there needed to be some changes which would allow developers looking to use WordPress’s backend, with its intuitive and well-loved admin panel, with the new way of doing the web.
The REST API gathers data for websites using a JSON format which allowed data such as users, taxonomies, posts and other elements to be retrieved and updated using an alternative front end.
With the REST API growing and growing in popularity, it was announced last year that the WordPress core would absorb the REST API so that it would become even more flexible allowing developers to create all sorts of new and exciting sites and apps.
Finally in December, the REST API was added to WordPress 4.4. There are still updates being carried out as all of the endpoints are being included into the WordPress core. Officially, there will be no version 2.0 release of the API because the 2.0 version is complete integration with the core.
