meta_ads_campaigns_update
Update an existing Meta Ads campaign by changing only the supplied fields. Modify name, status, bid strategy, or daily budget while leaving other settings unchanged.
Instructions
Updates fields on an existing campaign. Partial update — only the supplied fields are changed. Returns the updated campaign. Mutating — not automatically reversible; record before-state with mureo_state_action_log_append if you may need to roll back. For status-only transitions prefer meta_ads_campaigns_pause / meta_ads_campaigns_enable, which are safer and map to a single explicit operator intent.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| name | No | New campaign name. | |
| status | No | New campaign status. Prefer the dedicated meta_ads_campaigns_pause / enable tools for ACTIVE ↔ PAUSED transitions. | |
| account_id | No | Meta Ads account ID in the format 'act_XXXXXXXXXX' (e.g. 'act_1234567890'). Optional — falls back to META_ADS_ACCOUNT_ID from the configured credentials. The leading 'act_' prefix is required. | |
| campaign_id | Yes | Campaign ID to update. | |
| bid_strategy | No | Bid strategy for automatic auction bidding. LOWEST_COST_WITHOUT_CAP is fully automatic (do NOT set bid_amount). LOWEST_COST_WITH_BID_CAP and COST_CAP both require a bid_amount on the ad set (the cap). LOWEST_COST_WITH_MIN_ROAS requires bid_constraints.roas_average_floor on the ad set. When set on the campaign, budgets typically live at the campaign (CBO) level; when set on the ad set, at the ad-set level. | |
| daily_budget | No | New daily budget in account currency minor units (cents for USD, yen for JPY). Only settable when the campaign is configured for CBO; ad-set-level budgets must be edited via meta_ads_ad_sets_update. |
