Text fields (title / description / tags) are pushed to the marketplace. warehouse_id assigns a TikTok Shop warehouse to the listing locally (required before listing.publish on TikTok) — pick one from listing.list_warehouses. Image and video updates have to go through the channel patch service in a follow-up tool; until that lands, do not accept them here (otherwise local content drifts away from the live listing without anyone knowing).
Parameters
Parent listing UUID.
New title.
New description.
New tag list. Etsy/Shopify only — passing tags on a TikTok listing is a no-op.
TikTok warehouse id to assign (TikTok Shop listings only; see listing.list_warehouses).
