# Update Adset Bid Value

> Updates the bid amount (Bid Cap / Cost Cap) or minimum ROAS of Meta Ads ad sets

Updates the bid amount (Bid Cap / Cost Cap) or minimum ROAS of Meta Ads ad sets. For BID\_CAP and COST\_CAP, `bid_value` is provided as an actual dollar value, NOT in cents (e.g. pass 10 for $10). Do not multiply by 100. For MIN_ROAS, `bid_value` is a plain decimal multiplier (e.g. 1.23 = 123% ROAS), not a currency value. IMPORTANT: `bid_amount` returned by meta_ads_get_adset_settings is raw from Meta in minor units (cents for USD, e.g. 1000 = $10) — divide by 100 before passing here.

| `bid_type`  | string or SelectableOption | Yes      | -       | The campaign bidding strategy this ad set belongs to. 'BID\_CAP' (Bid cap) and 'COST\_CAP' (Cost per result goal) write to bid\_amount. 'MIN\_ROAS' (ROAS goal) writes to bid\_constraints.roas\_average\_floor.                                                                                                                                                                                                                                                             |

Do not multiply by 100. For MIN_ROAS: minimum ROAS as a plain decimal multiplier (e.g. 1.23 for 123%) — not a currency value. IMPORTANT: `bid_amount` returned by meta_ads_get_adset_settings is raw from Meta in the account's minor currency units (cents for USD, e.g. 1000 = $10) — divide by 100 before passing here for BID\_CAP/COST\_CAP. |
