FAQ

Questions about set_openai_ads_daily_spend_limit

What does the set_openai_ads_daily_spend_limit tool do? +

Create or change the ACCOUNT-WIDE DAILY SPENDING LIMIT on ChatGPT Ads: the most all campaigns together may spend each day, renewing at midnight in the account timezone, until it is removed or reaches its optional end date. OpenAI offers it only on ad accounts with postpaid INVOICE billing and it needs billing-management permission; a card-billed account is refused whatever key is used. amount is per day in the account currency and is required even when only the end date changes (0 stops account spend). A NEW limit starts tomorrow or later: list_openai_ads_spend_windows names the earliest start date. On an existing limit leave startDate out, because its start cannot change. An account can hold SEVERAL non-overlapping daily rules (list_openai_ads_spend_windows returns each with a windowId): pass windowId to change one, or newRule:true (with startDate) to add another; with more than one rule OpenAI requires the windowId. endDate is exclusive; noEndDate:true clears it. A daily limit and a date-range window cannot overlap. Lowering it can stop delivery and raising it lets campaigns spend up to their own budgets, so show the user the current and new values first: without confirm:true AND expectedRevision (the revision list_openai_ads_spend_windows returns) nothing changes and the reply states what would. The result is read back from ChatGPT Ads. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
