# Update Adset Budget

> Updates the budget (daily or lifetime) of Meta Ads ad sets for budget management

Updates the budget (daily or lifetime) of Meta Ads ad sets for budget management. `budget_value` is the amount in the account currency exactly as shown in Ads Manager (e.g. 100 for \$100, 300000 for COP 300,000); the backend applies Meta's currency offset, never multiply yourself. IMPORTANT: budgets returned by meta\_ads\_get\_adset\_settings (daily\_budget, lifetime\_budget, etc.) are raw Meta minor units — divide by that row's `currency_offset` (100 for most currencies, 1 for CLP, COP, CRC, HUF, ISK, IDR, JPY, KRW, PYG, TWD, VND) before passing here.
