The Best GoHighLevel Integrations and Apps in 2026
GoHighLevel is where agencies and local businesses run the whole funnel — pipelines, booking, SMS and email campaigns, and payments — all under one login. But it only earns its keep when it’s wired to the payment processor, phone provider, and books you already use. The platform ships with 25-plus native integrations, and its App Marketplace stretches that to roughly 1,500 more.
Here are the GoHighLevel integrations actually worth setting up, grouped by what they do — and then the way to connect HighLevel to anything with an API, even when no native integration exists.
Payments: Stripe, PayPal, NMI, Authorize.net, Square
Take money inside order forms, invoices, and payment links.
- Stripe — the default processor for order forms, subscriptions, invoices, and payment links inside HighLevel.
- PayPal — accept PayPal on order forms and affiliate payouts, now with Pay Later options.
- NMI — a white-label gateway for credit and debit card payments across order forms, stores, and invoices, including recurring charges.
- Authorize.net — take card payments, calendar-booking payments, and affiliate payouts (USD and CAD).
- Square — an alternative processor for businesses already on Square.
Communication: Twilio, Mailgun, and Slack
- Twilio — powers SMS, MMS, and voice calls directly from the CRM; it’s the backbone of HighLevel’s messaging.
- Mailgun — handles bulk email delivery so campaigns land in the inbox.
- Slack — get notified in a channel when a lead comes in, an appointment books, a deal closes, or a pipeline stage changes.
Ads and Google: Facebook, Instagram, Google Ads, Google Business Profile
- Facebook & Instagram — sync lead ads, run Messenger and Instagram DM conversations, and manage ad creative from the ad manager.
- Google Ads — create and track campaigns alongside your funnels.
- Google Business Profile — manage listings, reviews, and Google messaging from one place.
Scheduling and meetings: Google Calendar and Zoom
- Google Calendar — two-way sync so HighLevel bookings stay off your personal calendar’s toes.
- Zoom — auto-generate a unique Zoom link on every calendar appointment.
E-commerce and accounting: Shopify and QuickBooks
- Shopify — sync store customers and orders into HighLevel for follow-up campaigns and automation.
- QuickBooks — link invoicing and payments to your accounting so financials stay reconciled.
No-code automation: Zapier and Make
- Zapier and Make — connect HighLevel to thousands of apps with simple triggers (“new contact → do X”). Great for straightforward field-mapping, though they’re built for basic automation, not for reasoning over your data.
The AI way to connect GoHighLevel to anything: Carly
Native connectors and the marketplace cover the common apps. But the moment you need HighLevel tied to a tool that isn’t on the list — or you want something smarter than “new contact → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools and, crucially, lets you bring your own API key to connect to anything with a REST API — GoHighLevel included. Instead of a fixed catalog, you get an agent that:
- Acts on triggers, 24/7 in the cloud — when a lead comes in, an appointment books, or a pipeline stage moves, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read the last five messages in this conversation, decide if the lead is qualified, and book a call or route it to a rep.”
- Ties HighLevel to the rest of your stack — updating a contact becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, CRM, and tasks.
- Builds the workflow from a plain-English description — tell it “when a deal moves to Won, send the client an onboarding email and create a kickoff task” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See the full Claude + GoHighLevel integration guide for how the API-key connection works.
How to connect GoHighLevel to a tool with no native integration
- In GoHighLevel, create a Private Integration token (Settings → Private Integrations) with the scopes you need.
- Paste your API token into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting HighLevel to whatever else you need, on triggers, without your laptop open.

GoHighLevel offers 25-plus native integrations — including Stripe, PayPal, NMI, Authorize.net, Twilio, Mailgun, Slack, Facebook, Instagram, Google Ads, Google Business Profile, Google Calendar, Zoom, Shopify, and QuickBooks — plus Zapier and Make for no-code automation, a roughly 1,500-app marketplace, and a REST API for custom connections.

How do I connect GoHighLevel to an app that isn’t listed?

How much does an AI automation for GoHighLevel cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Your GoHighLevel plan and API access are separate.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
