Marketing API performance for the shop's connected ad account over a preset window: account-level totals (impressions, clicks, reach, spend, CTR, CPM, conversions) plus a per-ad table carrying the same metrics alongside each ad's creative — thumbnail, headline, body copy, link, call-to-action, and the branded-content partner's Instagram account for Partnership ads.

conversions is the sum of every entry in Meta's actions breakdown, because the insights edge exposes no single conversions field — read it as total attributed actions, not purchases. spend and the derived rates are in currency, the ad account's own currency, which need not match the shop's TikTok currency.

This is paid Meta data straight from the Marketing API and is unrelated to the rev-share attribution figures at /meta-ads/campaigns/{campaign_id}/rollups, which come from Reacher's own ledger — do not add them together. Sub-fetches are best-effort: a failing insights edge yields zeros and an empty ad list rather than an error. Returns 400 when the shop has no ad account linked. Single shop only.
