Just a few hours ago, a patch from the WordPress REST API project was merged into the WordPress 4.4 core that was under development. That patch came from the same WordPress REST API plugin we introduced on this site before.
Does that mean WordPress 4.4 would become the first version of WordPress with full REST API support? Not necessarily. What was merged into core this time was only part of the plugin. When WordPress 4.4 shipped, only some REST API functionality might have been available, and it was also possible that no practical REST API functionality would be usable yet. Based on the development pace at the time, fully usable REST API support likely had to wait until WordPress 4.5.
We have published a few articles on this site explaining how to use the WordPress REST API. If you are interested, the following articles are worth reading:
- Use the REST API Console plugin to explore the WordPress REST API.
- WordPress JSON REST API (WP API) documentation for creating, retrieving, editing, and deleting posts.
This merge was still an important signal, because it showed that the REST API was no longer just an external plugin experiment and was steadily moving toward becoming part of WordPress itself.
