           Use the `/events` endpoint to notify Topsort about significant consumer interactions on the marketplace app:
-          impressions — ad promotions become visible to the consumer;
-          clicks — the consumer clicks on an ad promotion;
-          and purchases — the consumer buys some products.
+          - **Impressions** — a set of impressions means such promotables have become visible to the consumer.
+          - **Clicks** — a click is sent to Topsort when the consumer has clicked on a promotable.
+          - **Purchases** — a purchase is sent to Topsort once a consumer places an order.
+
+          For promoted interactions, include the `resolvedBidId` field from the `/v2/auctions` response.
+          For unpromoted interactions, include the `entity` field to describe what was interacted with.

         In case you cannot send an impression when the product becomes visible, send us an impression event when the product was rendered in the HTML or, if that's also not possible, when your API returns the results.
         It is important to select the most specific event so that your vendors have more accurate CTR metrics, which will allow them to better predict their campaigns.
