What is the REST API Structure of WordPress?

The WordPress REST API structure allows developers to interact with site data using HTTP requests in a standardized way. It follows a URL-based endpoint structure, usually starting with /wp-json/, followed by the namespace, version, and route. For example, /wp-json/wp/v2/posts retrieves posts. The API supports GET, POST, PUT, PATCH, and DELETE methods, enabling reading, creating, updating, and deleting content. Responses are returned in JSON format, making it compatible with modern frontend frameworks like React or Vue. Developers can also create custom endpoints for plugins or themes, allowing WordPress to serve as a headless CMS for flexible, dynamic web applications.
