How to Use the Meta Business Manager Connector in Muse

1. The short answer

As of October 25, 2026, Meta Business Manager is a live connector in Muse. It arrived with the Muse for Small Business set announced September 29, 2026, when Meta said Muse could link to Meta ad accounts, Facebook Pages, and Instagram professional accounts in a few clicks. It was listed in the in app checks on September 30 and October 15, 2026 among the 54 connectors in the web app, and nothing in October changed how it works. It connects your advertising and business assets to Muse, so you can ask Muse to review how your ads are performing, draft campaign ideas from what already ran, and check spend across your accounts in plain words instead of inside Ads Manager.

Here is the honest version. The Meta Business Manager connector is the one connector on this page where a mistake costs real money, because it touches ad spend. That is also why it is the most valuable one for an advertiser who runs Meta ads every week. The value is not that Muse can open Ads Manager. Any browser can do that. The value is that Muse can reason across your ad accounts, your Pages, and your Instagram professional account at once: which ads are actually working, which ones are burning budget, and what to try next, in words you can act on. The rest of this guide covers how to connect it, what it can actually do, the money safety rules to set before you ask anything, and the limits we could not verify.

2. What you need

• Muse access. You need an account with access first, in the United States, Canada, or Japan, where Muse has launched. Japan joined on October 23, 2026.
• A Meta Business Manager account with ad accounts attached. The connector reads your business assets, so you need admin or advertiser access to the ad accounts and Pages you want Muse to see. If you only run ads from a personal ad account with no Business Manager, sort that out in Meta first.
• Your Facebook sign in. Business Manager signs in through Facebook, so have that login ready before you start.
• Approvals set to ask me, and a spend rule. Before you connect anything that can touch ad spend, set approvals so nothing publishes or spends without your tap. Meta states the rule plainly: nothing publishes, sends, or spends without your approval. This is the single most important step on this page.
• Our connectors list, for context. Meta Business Manager is one of 54 connectors in the web app, checked October 15, 2026, and one of the 7 Meta app connectors. Our complete Muse connectors list shows where it sits and which ones are announced but not yet live.

3. How to connect it, step by step

The connection itself takes a few minutes. The setup around it matters more, so run the steps in order and do not skip the approvals step at the end. Do not ask Muse to change anything about your ads on the first day.

1. Open Muse and go to Settings. The connectors list lives there. What is printed there is what your account has, because rollout is staged and two accounts can see different lists on the same day.
2. Find Meta Business Manager in the connectors list and open it. It sits with the other Meta apps, next to Facebook, Instagram, Instagram Messages, Messenger, Threads, and Threads Messages. If it is not listed, your account has not received it yet. There is nothing to install and nothing you broke. Check again in a few days.
3. Sign in with Facebook. Use the Facebook account that has access to the Business Manager you want Muse to see. The business assets attached to that login are the ones Muse will be able to read.
4. Grant the access Muse asks for, and read it twice. Muse needs permission to read your ad accounts, Pages, and business assets. Read the permission screen before you accept it. If a scope surprises you, stop and check what it covers before continuing. Ad account access is not a scope to wave through.
5. Set approvals to ask me. In Muse settings, set approvals so that publishing and spending always wait for you. This is what stops Muse from ever launching, editing, or funding a campaign you have not read.
6. Test with a read only request. Ask Muse to summarize how your ad accounts performed in the last 7 days. Read the summary against Ads Manager. If the numbers match, the connection is good. Do not ask it to change anything on the first day.
7. Use it read only for a week. Reviews, summaries, and drafts only. Once you trust what it reads and how it reports spend, start approving small changes one at a time, and check each one in Ads Manager after.

Copy this prompt

You are my ads analyst. Use my Meta Business Manager connector only.
Rules: you never publish, edit, pause, or fund any ad without my explicit approval. You read, summarize, compare, and draft. I approve every change.
My business: [what you sell, in one line]
Every Monday, do this in order.
1. Summarize the last 7 days across my ad accounts: spend, results, and cost per result for each campaign.
2. Name the 3 best performing ads and the 3 worst, and tell me why each one is winning or losing.
3. Flag any campaign whose cost per result rose sharply, and tell me by how much.
4. Draft 3 new ad angles based on the winners. Show me the drafts. Do not publish anything.
5. End with the one change I should make first this week, and why.

4. What it actually does

The connector earns its place with four uses. Everything else is a variation on one of them. Meta announced this set with sample requests like reviewing the year of sales, campaigns, and social activity and producing a growth plan, and reviewing the month of financial performance to find expenses that look off. Those are the jobs this connector is built for.

The weekly ad review

Ask Muse for the last 7 days across your ad accounts: spend, results, and cost per result for each campaign. This is the single highest value use, and it is the one to build a habit around. A good review names the winners and the losers and tells you why, and it takes five minutes to read instead of an hour inside Ads Manager. Run it every Monday before you touch any budget. The review gets better once Muse has a few weeks of your history to compare against, because a number only means something next to the number from last week.

Find what is burning budget

Ask Muse to find the campaigns whose cost per result rose sharply, the ad sets that spent without converting, and the ads that got impressions but no clicks. This is different from sorting a table yourself, because Muse reads the pattern and tells you the story: this ad stopped working on Thursday, this audience is exhausted, this creative has been running too long. Use it the moment a campaign feels off, not at the end of the month when the money is already gone. A campaign that quietly doubles in cost over two weeks is the most expensive mistake in Meta advertising, and it is exactly the one a weekly review catches.

Draft campaigns from what already worked

Meta says Muse can draft ad campaigns and review existing ad content to improve performance. Ask Muse to study your best performing ads and draft new angles from them: new hooks, new offers, new audiences to test. The drafts arrive for your approval, and the approval step is the whole point: you read, you edit, you launch. The drafts get better over a few weeks because Muse learns which of your angles actually converted and which ones only sounded good. The failure mode to avoid is approving a campaign you did not read. A campaign you did not read is spend you did not choose.

One view across Pages and Instagram

Ask Muse to pull together your Facebook Page, your Instagram professional account, and your ad accounts in one answer: what you posted, what you promoted, and what it cost. This beats checking three tools when you want to know whether the post that did well organically is also the one worth putting money behind. If you run a business from these accounts, pair this with the money view in our Stripe connector guide, which covers asking Muse about revenue in plain words, so you can compare what the ads cost against what the store actually took in.

Spot the change before the bill arrives

Some of the most valuable work this connector does is boring: noticing that spend jumped, that an ad account hit a limit, or that a campaign you thought was paused is still running. Ask Muse to flag anything that changed sharply since last week: spend, cost per result, or results per day. Run it once a week, on Monday, and treat the list it returns as your first job of the week. A short check that catches a runaway campaign on Monday is worth more than a perfect analysis that arrives after the budget is gone. If you advertise every week, this one use alone can pay for the habit, because the campaigns that drift are usually the ones spending the most.

5. Money safety: the rules to set first

Money safety is not a section to skim on this page. This connector touches ad spend, so set these rules before you ask Muse to do anything with your ads.

• Approvals on ask me, always. Meta states the rule plainly: nothing publishes, sends, or spends without your approval. Keep it that way. If you turn approvals off for convenience, you lose the one control that stands between a draft and a charge.
• Read only for the first week. Reviews, summaries, and drafts only. Check every number Muse quotes against Ads Manager before you act on it. A wrong cost per result acted on fast is worse than a slow read you verified.
• Set a test budget rule for yourself. When you do start approving changes, approve small ones first: a new ad angle on a small budget, not a full campaign rebuild. Scale what works after you see the result in Ads Manager.
• Know what you have not verified. We could not confirm from public sources whether Muse can create a campaign, pause an ad, or change a budget directly, or whether it can only draft and report. Treat drafting and reporting as the confirmed ground, and test any change action yourself on a small campaign before relying on it.
• Keep billing separate in your head. This connector reads your ad accounts. It does not replace your payment method, your billing settings, or your spend limits in Business Manager. Set your account spend limit in Business Manager itself, so a mistake has a ceiling even if an approval slips through.

6. What it cannot do

The limits are honest and worth knowing before you lean on the connector. Some of these we could not verify from public sources, and we say so where that is the case.

• It cannot spend without your approval when approvals are set right. That is a feature, not a bug. If you turn approvals off, you lose the safety net, so keep them on for anything that touches money.
• It cannot see ad accounts you never connected. Accounts in other Business Managers, other logins, and other tools are invisible to it. It reasons from what you connected, nothing more. The account you sign in with decides what Muse can see.
• Creating, pausing, and editing campaigns is unverified. We could not confirm from public sources which change actions Muse can take inside an ad account. Meta says it can draft campaigns and review ad content. Drafting is confirmed ground. Assume every change needs your approval and your check in Ads Manager after.
• It cannot guarantee it read the numbers right. A summary can misread a metric, mix up two campaigns, or quote a cost from the wrong date range. Check anything that touches spend, a budget decision, or a client report against Ads Manager before you act on it.
• It cannot fix a messy ad account. If your account is a pile of old campaigns with no naming system and no clear structure, Muse will summarize the pile. The review gets dramatically better once you pause what is dead and name what is live.
• It cannot run ads on other platforms. This connector is Meta only: Facebook and Instagram. Google Ads, TikTok Ads, and every other platform need their own tool. Do not expect one connector to report on spend it cannot see.

7. What to watch for

As of October 25, 2026, Meta Business Manager is a settled connector: announced September 29, 2026 with the Muse for Small Business set, listed in the September 30 and October 15 in app checks of the 54 web app connectors, with no October change to how it works. There is no October update to chase, so the habits around it still matter. Check every number against Ads Manager for the first week, especially spend and cost per result. A wrong number acted on fast is worse than a slow read you verified.

Be careful with client accounts. If you manage ads for clients, the account you connect is the account Muse sees, and the drafts it writes are in your voice, not your client voice. Set a rule for yourself: Muse drafts, you read, you send, and your client approves before anything goes live. The moment you start approving without reading is the moment the connector stops being an assistant and starts being a liability, and with client money that liability has a name attached to it.

Check your data controls. In Muse settings, open Data controls and look at the switch for helping improve the models. If you do not want your chats used for training, turn it off before you start asking Muse to read your ad accounts. That switch controls whether Meta may use your chats to train future models. Ad performance is business data, so this switch deserves a deliberate choice, not a default.

Finally, remember that this connector is one of several business connectors that arrived together on September 29. Asana, Box, Canva, Dropbox, Figma, Granola, HighLevel, QuickBooks, Klaviyo, Lovable, Notion, Shopify, Slack, Stripe, and Zoom were announced in the same set. The guides for the others in that set live on our connectors list, and the Shopify and Stripe guides are the natural next reads if you want Muse to see both what your ads cost and what your store earned.

Frequently asked questions

Can Muse spend money on my ads?

Not without your approval. Meta states that nothing publishes, sends, or spends without your approval. Keep your approvals set to ask me, and every change waits for your tap.

What does the Meta Business Manager connector actually connect?

Your Meta business assets: ad accounts, Facebook Pages, and Instagram professional accounts. It was announced on September 29, 2026 as part of the Muse for Small Business set.

Can Muse create a campaign for me?

Meta says Muse can draft ad campaigns and review existing ad content. We could not verify from public sources whether it can create, pause, or edit a campaign directly. Treat drafting and reporting as confirmed, and check every change in Ads Manager.

Can I use this connector outside the United States, Canada, and Japan?

Not yet. Muse itself has launched in the United States, Canada, and Japan only. Join the waitlist and we will send you a fresh code on launch day in your country.

What happens if I disconnect Meta Business Manager?

Muse loses access to those ad accounts and Pages. Your ads keep running as they were, and nothing Muse drafted is published after you disconnect. You can reconnect later.

Is my ad data used to train Muse?

There is a Data controls switch in Muse settings for helping improve the models. If you do not want your chats used for training, turn it off before you start asking Muse to read your ad accounts.
