To set a daily spend guard on Facebook ads with Claude or ChatGPT, choose the campaigns and a daily limit, and ask the assistant to turn on a spend guard. It runs on Meta's own automated rules, so it works when nobody is watching. Every 30 minutes Meta checks each campaign and pauses it once spend reaches a set share of your limit, 90 percent by default.
A guard protects you from a runaway day. It is built on Meta's automated rules, so the check happens inside Meta. Your assistant uses:
set_fb_daily_spend_guard turns a guard on for chosen campaigns or off by its guard ID.get_fb_spend_limits lists active guards and how close each campaign is to its limit.The report reads. set_fb_daily_spend_guard creates or switches off a rule in the account.
| Tool | What it needs |
|---|---|
| set_fb_daily_spend_guard | Changes the account. To turn on: campaign IDs, as text, and a daily limit. Optional: the pause share and whether to resume next day. To turn off: the guard ID. |
| get_fb_spend_limits | Reads only. Optional: campaign IDs. |
Each campaign is counted on its own. Meta's figures arrive late and a campaign keeps spending between checks, which is why the guard pauses at 90 percent rather than 100. Resuming at midnight turns spend back on with nobody watching, so it needs your explicit yes.
These steps use Claude. PaidSync.ai also works in ChatGPT, so you can set a daily spend guard on Facebook ads there with the same prompts.
Sign up at paidsync.ai, then connect Meta on Meta's own sign-in screen. Know your daily limit per campaign in account currency.
Add PaidSync.ai from Claude's connector directory and sign in. Ask "list my Facebook ad accounts" and choose the one where you want to set a daily spend guard on Facebook ads.
Name the campaigns and the most each may spend in a day.
Decide whether paused campaigns come back at midnight in the account time zone.
Claude shows the guard as a dry run. If you chose resume, it asks for your yes before it applies.
Ask for spend limits and look for the guard against each campaign. To switch it off later, use the guard ID.

No. A cap is a lifetime ceiling and the guard is a daily one. Use both for full cover.
