A content URL previously returned by the API (signed or unsigned), or a
bare object key. The server resolves it back to a known object it owns,
re-checks your access, and mints a fresh URL — useful when a cached
signed URL has expired and you want a new one without re-fetching the
whole parent resource.
Response
Freshly-signed content URL
signed_urlstring nullable
CloudFront signed URL for private content. Omitted when the object is
public or signing is unavailable.
urlstring required
Legacy unsigned CDN URL. Populated for backwards compatibility; prefer
signed_url when present.
