wp-abilities-api

To register WordPress abilities via REST API, use the wp_abilities_api_categories_init and wp_abilities_api_init hooks in your PHP plugin to define categories and abilities, ensuring show_in_rest meta flags are set so they are exposed at wp-json/wp-abilities/v1 for client consumption.

WordPress abilities may not show up in the REST API if categories are not registered before abilities using the correct hooks, or if show_in_rest meta flags are missing. Ensure wp_abilities_api_categories_init fires before wp_abilities_api_init to diagnose visibility issues.

Yes, you can integrate the WordPress Abilities API into any plugin or theme. Register ability categories and abilities with stable IDs and labels in PHP, and enable client-side consumption through the WordPress Abilities package without requiring external dependencies.

The WordPress Abilities API is a system to register structured abilities and categories in PHP and expose them via REST endpoints. You need it when building features that require client-side discovery and consumption of registered abilities through the wp-abilities/v1 endpoint.

Yes, the WordPress Abilities API enforces correct hook usage, requiring categories to be registered before abilities. You must use the wp_abilities_api_categories_init hook for categories and wp_abilities_api_init for abilities to ensure proper REST exposure and client consumption.

The best way to structure WordPress abilities for client-side consumption is to assign stable IDs, human-readable labels, descriptions, and categories during PHP registration. This ensures clients can discover and use them reliably through the WordPress Abilities package and REST endpoints.
