wp-abilities-api

Register abilities and categories using the wp_abilities_api_categories_init and wp_abilities_api_init hooks in PHP. Set show_in_rest to true to expose them under the wp-abilities/v1 REST endpoint for client discovery.

The WordPress Abilities API lets developers define capabilities in PHP, expose them via REST, and consume them from JavaScript. It provides a consistent, secure way to handle runtime permission checks and UI gating in client code.

Yes, registered WordPress abilities can be consumed from JavaScript using the @wordpress/abilities package for runtime permission checks and UI gating, accessing them via the wp-abilities/v1 REST endpoint.

The WordPress Abilities API requires WordPress 6.9 or higher for PHP-based plugins and themes. This version provides the necessary wp_abilities_api_init hooks for proper category and ability registration.

A REST endpoint returns not found for WordPress abilities when show_in_rest is false or permission handling is misconfigured. Verify registration via wp_register_ability and ensure proper permission callbacks are applied to expose visibility.
