# meta_update_adset_configuration

> Update targeting, optimization, placements, attribution, bidding, budget or schedule.

[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Meta Ads](https://www.getmcpads.com/docs/sources/meta-ads)

Update targeting, optimization, placements, attribution, bidding, budget or schedule. Targeting is a COMPLETE replacement, not a partial merge. Status is unchanged. Local preview by default. No automatic retry. Account ownership is checked before Meta validation or mutation.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
