A metric TikTok adds later comes back as `unknown`. Rows use camelCase keys from TikTok's fields, for example `productId`, `productName`, `deliveredOrderCount`, `negativeOrderCount` and `topReviewReasons` for products. The list isn't paged. TikTok has no top items for `SFCR` or `IM_DSAT`, so those codes are rejected; use Metric problem details for them. US shops only.
