The campaign's current settings, normalized from TikTok's raw campaign/gmv_max/info payload into a stable snake_case object: status, target_roas, daily_budget, schedule window, auto_budget_enabled, product_selection, roi_protection_enabled, affiliate_posts_enabled, and placements. Settings TikTok did not report are null. Single shop only — set x-shop-id to the campaign's owning shop. 404 if the campaign is not found in this shop.

source=synced (default) reads Reacher's last sync, which can be a few hours old. source=live reads the campaign from TikTok on this request — use it to confirm a change (e.g. a new target ROAS) took effect.
