Topsort now supports **render events**, giving marketplaces more visibility into what happens between winning an auction and an ad being viewed.

A render event records when a sponsored ad is inserted into a page, separately from an impression, which records when the ad becomes visible to the shopper.

By reporting both events, marketplaces can more accurately measure ad delivery and distinguish ads that were rendered from those that were actually viewed. This provides better visibility into the auction-to-impression funnel and can help identify placement or implementation issues when ads are returned or rendered but do not become viewable.

Render events are available through the Events API and are associated with the winning ad using its `resolvedBidId`.

See [docs](/en/api-reference/events/report-events).
