The Best HubSpot Integrations and Apps in 2026
HubSpot is a CRM and marketing, sales, and service platform, but it only earns its keep when it’s wired to the tools where your work actually happens — your inbox, your phone system, your store, your books. The HubSpot App Marketplace passed 2,000+ listed apps and 2.5 million active installs in 2026, on top of the native connectors HubSpot builds and maintains itself, so the hard part isn’t finding an integration — it’s knowing which ones are worth your time.
Here are the HubSpot integrations actually worth setting up, grouped by what they do — and then the way to connect HubSpot to anything with an API.
Email and inbox: Gmail, Outlook, Instantly
- Gmail — Two-way sync that logs sent and received email to the right contact, adds tracking and templates inside Gmail, and lets you enroll contacts in sequences without leaving the inbox.
- Outlook / Microsoft 365 — Same connected-inbox experience for Outlook users: email logging, open and click tracking, meeting links, and the HubSpot sales sidebar in Outlook.
- Instantly / cold-email tools — Push replies and engagement from outbound campaigns back into HubSpot so reps see the full thread on the contact record.
Calling and meetings: Aircall, Zoom, Google Meet
- Aircall — Cloud phone system that logs calls, recordings, and voicemails against HubSpot contacts and can trigger workflows off call outcomes.
- Zoom — Adds Zoom links to HubSpot meetings, syncs registrants and attendance from webinars, and logs meeting activity to the timeline.
- Google Meet / Microsoft Teams — Native meeting-link options inside HubSpot’s scheduling tool so booked meetings come with a working video link automatically.
E-commerce and payments: Shopify, Stripe, WooCommerce
- Shopify — Syncs customers, orders, and abandoned carts into HubSpot so you can trigger recovery emails and segment by purchase behavior.
- Stripe — Connects subscription and payment data to contacts, powering churn alerts, receipts, and revenue-based segmentation.
- WooCommerce — Brings store customers and order history into HubSpot for the same lifecycle marketing on WordPress-based stores.
Accounting: QuickBooks, Xero
- QuickBooks Online — Two-way sync of customers, invoices, and payment status so sales and finance work from the same record instead of re-keying deals into the books.
- Xero — Similar invoice and contact sync for teams on Xero, with deal-to-invoice handoff when a deal closes.
Team chat and forms: Slack, Typeform, Jotform
- Slack — Sends deal, ticket, and workflow notifications into channels, and unfurls HubSpot record links into rich, interactive previews so context lives where the team already talks.
- Typeform — Pipes form and survey responses straight into HubSpot as new or updated contacts, with answers mapped to properties.
- Jotform / SurveyMonkey — Same idea for other form and survey tools, feeding responses into lists and workflows.
Advertising: Google Ads, Meta, LinkedIn Ads
- Google Ads — Connects ad clicks to closed deals so you can report real ROI and sync HubSpot lists as audiences.
- Meta (Facebook / Instagram) Ads — Syncs lead-ad submissions into HubSpot instantly and builds audiences from CRM segments.
- LinkedIn Ads — Pulls lead-gen form submissions into HubSpot and mirrors CRM lists to LinkedIn for retargeting.
No-code automation: Zapier and Make
- Zapier and Make connect HubSpot to thousands of apps through triggers and actions. They’re good for basic field-mapping — “new HubSpot contact, add a row to a sheet” — but they copy fields on a schedule; they don’t reason about which record deserves action or what to write in a follow-up.
The AI way to connect HubSpot to anything: Carly
The marketplace covers the popular apps, and Zapier covers the mechanical copy-a-field jobs. What’s missing is a layer that can think about your CRM data and act on it around the clock. That’s where an AI executive assistant comes in.
Carly is an AI executive assistant that connects to 200+ tools — HubSpot included — and lets you bring your own API key to connect to anything else with a REST API.
- Acts on triggers 24/7 in the cloud — watches for new deals, stalled contacts, or inbound replies and responds without you being logged in.
- Reasons over your data, not just copies fields — reads the deal history and decides what a good next step or follow-up actually is, instead of blindly mapping columns.
- Ties HubSpot to the rest of your stack — Gmail, Outlook, your calendar, Slack, and your other CRM and finance tools, so a HubSpot change can ripple through everywhere it matters.
- Builds the workflow from a plain-English description — you describe what you want; Carly assembles the steps.
Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited.
Carly also integrates with HubSpot.
How to connect HubSpot to a tool with no native integration
HubSpot exposes a public REST API, and the modern way to authenticate is a private app access token (HubSpot deprecated legacy API keys in favor of these).
- In HubSpot, go to Settings → Integrations → Private Apps, create a private app, choose the scopes it needs, and copy the access token from the Auth tab (you’ll need super-admin access).
- Paste that token into Carly on the integrations page.
- Describe the workflow in plain English — “when a deal moves to Closed Won in HubSpot, draft a welcome email and create the invoice” — and Carly builds it.
Frequently Asked Questions
Does HubSpot have integrations?
Yes. HubSpot builds native integrations for major tools like Gmail, Outlook, Slack, Shopify, and QuickBooks, and its App Marketplace lists 2,000+ third-party apps on top of that.
What is the best HubSpot integration for automation?
For simple field-syncing, Zapier or Make handle it. For automation that reads your CRM data and acts on it — drafting follow-ups, deciding next steps, moving data across tools — an AI assistant like Carly does the reasoning that copy-field tools can’t.
How do I connect HubSpot to an app that isn’t listed?
Create a private app in HubSpot to get an API access token, then paste it into a tool like Carly that supports bring-your-own-key. From there you can wire HubSpot to any app with a REST API.
How much does an AI automation for HubSpot cost?
With Carly, AI agents start at $35/month, and the non-AI steps in a workflow run free and unlimited.

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."
