Joomla Web Services API
The built-in Joomla Web Services API provides RESTful JSON endpoints for managing articles, categories, contacts, banners, menus, modules, tags, custom fields, and user accounts in a Joomla installation. Authentication uses Bearer tokens issued per-user. The API is available in Joomla 4.x and later and follows the {base_url}/api/index.php/v1/ URL pattern.
