When requesting an article via /api/v3/articles/:id with ?kb_language=, the API always falls back to the default language if the requested localization doesn’t exist. This makes it impossible to detect which localizations actually exist when consuming the API. Expected Behavior: API should provide the actual kb_language value(s) available for that article in the response body. This allows integrators to detect existing localizations instead of guessing. Proposed Fix: Include kb_language in the article object returned by /api/v3/articles/:id. Ensure webhook payloads also include kb_language info when firing.
