Window totals for the whole shop from the Seller Center overview, split by the channel the sale came through: video (creator vs seller), live (creator vs seller), and product card (shop tab vs search), plus product impressions / clicks and the derived click-through rate.

comparison carries the comparison-period totals TikTok attaches to each day, summed across the window, and gmv_change_pct derives the swing. TikTok chooses those periods (typically the immediately preceding equal-length window), so treat it as a directional benchmark rather than a window you control.

Related: POST /shop-gmv/timeseries gives the same channel hierarchy day by day, and POST /shop-gmv/summary gives the window totals without the comparison, product-card counts or listing impressions added here. aov is window GMV / window orders; customers is the sum of daily unique-buyer counts, so a buyer who purchased on two days is counted twice. Max range 90 days. Single-shop only — set x-shop-id to a specific shop ID. An empty result is a normal 200 response: Seller Center collection is per-shop and still rolling out.
