Sitefinity CMS Headless OData Services
Sitefinity CMS exposes its content as OData v4 web services under a configurable service route (by default /api/default) on the customer's own Sitefinity instance. The headless API serves content types, taxonomies, pages, media and custom modules with full OData query syntax ($select, $expand, $filter, $orderby), bearer-token authentication and a $metadata document that is the machine-readable contract for each installation.
