To expose custom post types via the WordPress REST API, use the show_in_rest argument when registering your custom post types and taxonomies. This allows the API to automatically handle data exposure and controller-based architecture for your content.

To secure WordPress REST API routes, implement permission callbacks within your route registration. This enforces proper authentication and authorization checks before the controller processes the request, ensuring data exposure is restricted to authorized users.

You need the WP_REST_Controller base class to build WordPress REST API endpoints because it enforces standard controller-based architecture. It simplifies endpoint creation by providing built-in methods for schema validation, permission checks, and response shaping.

The best way to structure controllers for a WordPress REST API plugin is to extend the WP_REST_Controller base class. This enforces a consistent controller-based architecture, route registration patterns, and JSON schema validation across all your custom endpoints.
