Exclude a video from GMV Max

Exclude ONE video (creative) from this shop's GMV Max delivery, by TikTok video_id, without excluding its creator — use this to cut an unprofitable creative (e.g. zero orders at $10+ spend) while the creator's other videos keep delivering. The reconcile job removes the creative from every active campaign it is delivering in within ~4 hours and verifies it flipped to EXCLUDED. Idempotent on (shop, video_id): re-excluding an already excluded video keeps its current applied_status. Requires read_write scope and an Idempotency-Key. Single shop only. For many videos at once use POST /gmv-max/excluded-videos/bulk.
