# Get the observed creative thumbnail

> PNG of the creative frame from the headless observation run of the review version identified by `creativeId` (use the queue's `reviewRef`). Served only to the storefront that owns the review, only for its current content version, and bounded to 600 px on the longest edge. 404 when the version has not been observed, produced no screenshot, or has been superseded by a resubmission. The row's `thumbnailUrl` points here; it is never a public URL.
