meta_ads_update_budget
Meta Ads tool. Update the budget or bid strategy of a Meta Ads campaign (CBO — campaign-level budget). Use meta_ads_update_adset_budget to update budget at the ad set level. Args: campaign_id: Campaign ID to update (required). daily_budget: New daily budget in the account currency's smallest unit, e.g. '5000' for ₪50. Leave blank to keep unchanged. lifetime_budget: New lifetime budget in smallest currency unit. Leave blank to keep unchanged. bid_strategy: LOWEST_COST_WITHOUT_CAP, LOWEST_COST_WITH_BID_CAP or COST_CAP. On a campaign that holds the budget this governs every ad set under it. Set LOWEST_COST_WITHOUT_CAP when ad sets are refused with "bid amount required" (1815857) on a campaign that inherited a bid cap from the account.
