meta_ads_campaigns_pause
Pauses a single Meta Ads campaign by setting its status to PAUSED, stopping spend immediately and cascading to active ad sets and ads. Reversible via rollback or re-enable.
Instructions
Pauses a single campaign by setting its status to PAUSED. Cascades to active ad sets and ads — nothing underneath the campaign will serve while it is PAUSED. Lightweight and reversible via rollback_apply or meta_ads_campaigns_enable. Returns the campaign id and new status. Use for immediate stop-spend situations; use meta_ads_campaigns_update with status='DELETED' to soft-delete instead.
