HighLevel in Muse: what Meta's connector can read and change

• Last verified October 28, 2026
• Updated Oct 28, 2026Published Oct 28, 2026

Meta's announcement of Muse for small business names HighLevel among its connectors, and HighLevel turns up on most of our trade guides, from HVAC shops to dental offices and real estate teams. This page looks at the connector on its own terms: what Muse can look up and do inside a HighLevel CRM, how the connection is approved and withdrawn, how agency and sub-account access differ, and what each company says it does with the data. It's written for owners, office managers and the agencies that run HighLevel on their behalf.

What the labels mean here:

How we built it: every source below was read on Oct 28, 2026, among them Meta's announcement, help page, terms, privacy policy and connector guidelines; HighLevel's Muse article, developer documentation, help articles on OAuth, HIPAA and texting, pricing page, privacy policy and press release; Zapier's docs; and the federal rules cited further down. We haven't signed in to Muse or linked it to a HighLevel account, so nothing on this page is tested, and we haven't looked at the approval screen or the scopes the Muse app requests.

Short version

• HighLevel's Muse app connects through OAuth: when you sign in, you choose the CRM sub-accounts Muse may use and approve the scopes it requests, and those scopes decide what it can touch. (Confirmed by vendor 6)
• HighLevel says the connection covers contacts, conversations, calendars and opportunities, along with payments, locations and custom fields, and that it can read records, update them and send messages when the approved scopes allow it. (Confirmed by vendor 6 7)
• Meta's connector rules make sending an email, or buying something, a sensitive action that asks for your approval every time. (Confirmed by vendor 3) HighLevel adds its own extra confirmation and safety checks before sensitive or irreversible operations run. (Confirmed by vendor 7)
• You can review and revoke the access later from Settings > Connected Apps in HighLevel. (Confirmed by vendor 6)
• HighLevel accounts aren't HIPAA compliant unless you buy its HIPAA add-on, which costs $297 a month, includes a business associate agreement and can't be cancelled once bought. (Confirmed by vendor 10)
• Muse's AI-training setting starts out on and includes what comes in through connectors; you can turn it off under Data controls. (Confirmed by vendor 5)

What Muse can read and change

Swipe the table sideways to see every column →

HighLevel's server hands every client four general tools rather than one per action: one lists the sub-accounts the connection can reach, one looks up available operations, one shows what an operation needs and how risky it is, and one runs it. Its worked example asks the assistant to look up a contact by email address, tag them and open a $5,000 opportunity in a named pipeline, all in one request. (Confirmed by vendor 7) HighLevel's developer catalog is written for every client, and we found nothing saying the Muse app gets all of it. (Unverified)

Connecting it

HighLevel's steps: in Muse, choose to connect an app and pick HighLevel, sign in to HighLevel if asked, choose the sub-accounts, check the scopes on the approval screen, approve, then confirm in Muse that HighLevel shows as connected. The Muse connection runs through its own address, services.leadconnectorhq.com/mcp/muse/v2/, and HighLevel says to follow that OAuth flow rather than the token-based setup it documents for other clients. (Confirmed by vendor 6) Meta's help article puts connectors under Settings, then Connectors, and says you can also ask Muse in chat to set one up. (Confirmed by vendor 2) Muse's terms require users to be 18 or older and make you responsible for each connection and its permissions. (Confirmed by vendor 4) Muse itself is limited to the US and Canada, according to Meta. (Confirmed by vendor 1)

What we couldn't pin down:

• Plan requirements. Neither company says which HighLevel plan the Muse app needs. (Unverified) HighLevel's pricing page lists Starter at $97 a month with three sub-accounts, Unlimited at $297 with "Basic API Access" and Agency Pro at $497 with "Advanced API Access", though its list of core features, which Starter also gets, names API access too. Each plan comes with a 14-day free trial. (Confirmed by vendor 11) Whether the OAuth connection counts against API access or needs a particular plan isn't stated. (Unverified)
• The scope list. HighLevel doesn't publish which scopes the Muse app requests, or whether you can approve some and decline others. (Unverified) Its general OAuth article gives sample scopes, such as one for viewing contacts and one for sending messages for you, and shows a bold warning when an app asks for sensitive access like changing team members' permissions. (Confirmed by vendor 8)
• Usage charges. We found nothing on whether texts or emails Muse sends are billed differently from ones you send yourself. (Unverified) HighLevel's pricing page says usage-based charges apply to its email, SMS and calling features. (Confirmed by vendor 11)

Permissions and approvals

Two separate layers decide what Muse can do, and both are worth setting on purpose.

A single connection goes to one sub-account by default. An agency can instead include several or all of its sub-accounts in one install; each request still runs against just one of them, the assistant asks which one when your request leaves it unclear, and a request for any sub-account you left out is refused. HighLevel says this agency-wide option is still rolling out. (Confirmed by vendor 7) Neither company says whether the agency-wide option is available in Muse yet. (Unverified)

On Meta's side, connector tools are sorted into reads, writes and sensitive writes. Ordinary reads and writes ask the first time and can be switched to Always allow afterward; sensitive ones, such as sending an email, ask every time with only Allow once or Deny. Muse has to ask once more whenever an approved action's details change. (Confirmed by vendor 3) Meta's launch post says Muse waits for your approval before it publishes, sends or spends. (Confirmed by vendor 1) We found nothing saying whether Meta classes a HighLevel text message as a sensitive write in the way it does email. (Unverified) Keep any tool that sends a text or email set to ask.

Disconnecting

In HighLevel, connected apps are listed under Settings > Connected Apps, and HighLevel advises reviewing that list regularly and revoking apps you no longer use. (Confirmed by vendor 6 8) We couldn't confirm whether that screen is at the agency level, the sub-account level or both for the Muse app. (Unverified) Meta's rules require connector makers to delete a user's data once access is withdrawn. (Confirmed by vendor 3)

What happens to your data

• Training on Meta's side. Muse's privacy policy turns on training of Meta's AI with your interactions from the first time you use Muse, counts connector information as part of those interactions, and applies a switch-off under Data controls to past interactions as well. Meta says it removes some personal details, such as names, phone numbers and email addresses, and disconnects the data from your account before training. (Confirmed by vendor 5) The terms also license Meta to use content drawn from connected services, and allow it to log what Muse does. (Confirmed by vendor 4) A HighLevel CRM holds your customers' names, numbers and message history, so settle this before connecting.
• What Muse passes to HighLevel. Meta says a connected app gets only the data a request needs. (Confirmed by vendor 2) Connector makers may not train models on it, sell it or use it for unrelated ads. (Confirmed by vendor 3)
• What HighLevel says. HighLevel's privacy policy says it doesn't train generalized, public AI models on your personal information and that it limits its AI subprocessors to the service you're using. The same policy also allows targeted advertising and, subject to an opt-out, selling or sharing personal information as state privacy laws define those terms. (Confirmed by vendor 12) We didn't find any HighLevel statement covering what it retains from requests that come in through Muse. (Unverified)

HighLevel's own MCP servers

Owners who'd rather not use Meta's listed app have other routes into HighLevel.

• HighLevel runs separate OAuth addresses for Claude, for ChatGPT and other OpenAI clients, and for Cursor, all reaching the same operation catalog. (Confirmed by vendor 7)
• Its older setup uses a private integration token, created under a sub-account's Settings with the scopes you choose, and a location ID, and HighLevel warns against exposing that token anywhere public. (Confirmed by vendor 14)
• Doing that yourself would make it a custom connector, and those skip Meta's review; Muse holds its login details in a vault Meta calls the Secure Credentials Store. (Confirmed by vendor 2)

HighLevel also goes by LeadConnector, and Zapier's LeadConnector app offers Zaps that add or update contacts and opportunities. (Confirmed by vendor 7 16) Zapier bills each tool call that succeeds via its MCP server as two tasks on your plan. (Confirmed by vendor 15)

Risks to keep a person on

Texts and emails reach real customers

HighLevel's announcement pitches the connector for managing leads, booking meetings, updating customer records and getting ready for customer conversations. (Confirmed by vendor 9) Every one of those can end in a message under your business name. Read the draft, the recipient and the sub-account before you approve a send.

Texting rules

The FCC's rule says a cell number called with an autodialer or a prerecorded voice needs that person's prior express consent, and for advertising or telemarketing, prior express written consent. (Confirmed by the FCC 17) Amendments taking effect Nov 25, 2026 let callers name one exclusive way to revoke consent and treat a revocation of one category of informational robocalls as covering only that category. (Confirmed by the FCC 18) Our real estate, HVAC and plumbing and insurance agency guides explain how these rules apply to business texting, so we don't repeat that here. Don't let Muse change opt-out handling or add contacts to a marketing list.

HighLevel says A2P 10DLC registration, done under Settings > Phone System > Trust Center, is needed for business texts to US recipients from standard 10-digit local numbers, and that carriers, not HighLevel, approve or reject it. Toll-free numbers go through a separate verification. (Confirmed by vendor 13) Muse doesn't change that requirement.

Marketing email

Under the FTC's CAN-SPAM rule, a sender can't charge a fee to opt out or demand anything beyond the recipient's email address and opt-out preferences. (Confirmed by the FTC 19) The other CAN-SPAM requirements are set out in our insurance agency and law firm guides. Keep unsubscribe links and suppression lists out of Muse's reach.

The wrong contact, or many at once

The developer catalog includes deleting contacts, bulk email campaigns, bulk media deletion, workflow publishing and phone-number purchases. (Confirmed by vendor 7) A request that matches two people named Smith, or the wrong sub-account in an agency install, can change or message the wrong customer. Name the contact and the sub-account exactly, ask Muse to list what it will touch before it acts, and decline any action that covers more records than you expected.

Health information

HighLevel's HIPAA add-on is bought at the agency level, can't be turned off, and must then be switched on separately for each sub-account that needs it. (Confirmed by vendor 10) Nothing we read says whether data that leaves HighLevel through Muse stays inside that protection. (Unverified) Our guide for dental and medical offices covers HIPAA and HighLevel in more depth; keep patient details out of Muse prompts until you've read it.

Data you can't fully pull back

Removing the connector stops new exchanges, yet anything Muse has stored in memory stays put until you have it deleted. (Confirmed by vendor 2 5) Settle the training setting before you connect a CRM full of customer conversations.

Treat this page as a summary of published sources, not as legal, marketing compliance or data security advice. Screens in Muse and HighLevel may have moved on since we read these pages, so check them yourself.

FAQ

Can Muse text my customers through HighLevel?

It can send messages if the scopes you approve allow it. (Confirmed by vendor 6 7) Whether Meta asks for approval on every text, as it does for email, isn't documented. (Unverified)
