WP REST API & Abilities API

Route Registration

Register routes on the rest_api_init hook using register_rest_route(). A route is the URL pattern; an endpoint is the method + callback bound to that route. For non-trivial endpoints, extend WP_REST_Controller for a structured CRUD pattern with built-in schema wiring.

Namespacing rules

• Always use a unique namespace: vendor/v1 (e.g. myplugin/v1).
• Never use wp/* unless contributing to WordPress core.
• For non-pretty permalinks, routes are accessed via ?rest_route=/namespace/route.
