WP REST API The REST API is an acronym for the RESTful Application Program Interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data. It is how the front end of an application (think “phone app” or “website”) can communicate with the data store (think “database” or “file system”) https://developer.wordpress.org/rest-api/. Versions 2.0 Beta A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. 12.1 and 2.0 Beta 13.1 are security releases to address a data privacy issue with the Users endpoint. Given certain parameters, private user data such as email addresses may be exposed to unauthenticated users.
