> Learn about availability for custom Link Preview connections.

A Link Preview is a real-time excerpt of authenticated content that unfurls in Notion when an authenticated user pastes a supported link in their workspace.

Custom Link Preview connections are no longer available for new developers to create. Existing supported Link Preview integrations continue to work for Notion users.
