The Best Shopify Integrations and Apps in 2026
Shopify runs the storefront, checkout, and inventory, but a store only earns its keep once it’s wired to the email tool, the review widget, the accountant’s books, and the carrier that prints your labels. The Shopify App Store crossed 18,000 apps in 2026 (roughly 18,300 as of May, adding 500-plus new apps a month), so the hard part isn’t finding an integration — it’s picking the handful that matter and skipping the bloat.
Here are the Shopify integrations actually worth setting up, grouped by what they do — and then the way to connect Shopify to anything with an API.
Email and SMS marketing: Klaviyo, Mailchimp
- Klaviyo — the most-used Shopify marketing app; syncs order and browsing behavior so you can trigger abandoned-cart, post-purchase, and win-back flows off real customer actions.
- Mailchimp — reconnected as an official Shopify channel; good for stores that want simpler broadcast campaigns and audience segments without Klaviyo’s flow complexity.
- Omnisend — email plus SMS in one app, built for e-commerce, with pre-built automations that pull Shopify product and order data.
Reviews and social proof: Judge.me, Yotpo
- Judge.me — the largest review app on the store with a near-perfect rating; collects photo and video reviews and syndicates them to Google, Meta Shops, and TikTok.
- Yotpo — reviews, loyalty, and SMS bundled together; heavier, but strong if you want one vendor across several growth surfaces.
- Loox — visual, photo-first reviews popular with DTC brands that live on aesthetics.
Subscriptions and loyalty: Recharge, Smile.io
- Recharge — the established subscription engine for recurring orders, “subscribe and save,” and churn management; deep hooks into Shopify checkout.
- Skio — a newer subscriptions challenger built on native Shopify checkout, popular with brands migrating off older tools.
- Smile.io — points, referrals, and VIP tiers to drive repeat purchases, synced to your Shopify customer records.
Shipping and fulfillment: ShipStation, AfterShip
- ShipStation — pulls orders in, batches labels across carriers, and pushes tracking back to Shopify; teams report it saving a couple of hours a day.
- AfterShip — branded post-purchase tracking pages and delivery notifications that cut “where is my order” tickets.
- ShipBob — outsourced fulfillment and warehousing that syncs inventory and orders with Shopify automatically.
Accounting: QuickBooks, Xero
- QuickBooks Online — syncs orders, payouts, fees, and taxes into your books so month-end reconciliation isn’t a manual export.
- Xero — the same idea for Xero shops; maps Shopify sales and Shopify Payments fees to the right ledger accounts.
Customer support: Gorgias, Zendesk
- Gorgias — a helpdesk built for Shopify; agents see full order history, refund and cancel from inside the ticket, and reply across email, chat, and social.
- Zendesk — broader, enterprise-grade support with a Shopify sidebar that surfaces order context on each ticket.
Sales channels: Meta, Google, TikTok, Shopify POS
- Meta (Facebook and Instagram) — the official channel syncs your catalog for Shops, product tags, and Advantage+ ad campaigns.
- Google and YouTube — free product listings, Performance Max campaigns, and Merchant Center sync from inside Shopify.
- TikTok — catalog sync and TikTok Shop so in-app checkout maps back to Shopify orders and inventory.
- Shopify POS — first-party point of sale that keeps in-store and online inventory, customers, and orders on one ledger.
No-code automation: Zapier and Make
- Zapier and Make — connect Shopify events (new order, new customer) to thousands of apps with simple field-mapping. Great for basic “when X, copy to Y” plumbing. They move data between fields, but they don’t reason over it — no judgment about which orders need a personal follow-up or how to phrase a reply.
The AI way to connect Shopify to anything: Carly
Carly is an AI executive assistant that connects to 200+ tools — Shopify included — and lets you bring your own API key to connect to anything else with a REST API. Instead of copying a field from one app to another, Carly reads your store data, decides what to do, and acts on it.
- Watches Shopify triggers (new orders, refunds, low stock, VIP customers) and acts on them 24/7 in the cloud, no laptop open.
- Reasons over the data — drafts a tailored reply to an unhappy customer, or flags which orders actually look fraudulent, rather than blindly copying a field.
- Ties Shopify to the rest of your stack: Gmail or Outlook, your calendar, your CRM, your accounting tool, and Slack.
- Builds the whole workflow from a plain-English description — you say what you want, Carly wires it up.
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Carly also integrates with Shopify.
How to connect Shopify to a tool with no native integration
- In Shopify admin, go to Settings → Apps and sales channels → Develop apps, create a custom app, choose your Admin API scopes, install it, and copy the Admin API access token (Shopify shows it once).
- Paste that token into Carly on the integrations page.
- Describe the workflow in plain English — “when an order over $500 comes in, draft a thank-you email and add the customer to my VIP list” — and Carly builds it.
Frequently Asked Questions
Does Shopify have integrations?
Yes. The Shopify App Store had more than 18,000 apps in 2026 covering email marketing, reviews, subscriptions, shipping, accounting, support, and every major sales channel, plus a public GraphQL Admin API for custom connections.
What is the best Shopify integration for automation?
Zapier and Make handle simple field-mapping between Shopify and other apps. For automation that actually reasons over your orders and customers — drafting replies, deciding which orders to flag, chaining Shopify to email and your CRM — an AI assistant like Carly does the thinking a field-mapper can’t.
How do I connect Shopify to an app that isn’t listed?
Create a custom app in Shopify admin under Develop apps, generate an Admin API access token, and paste it into a tool that accepts your key — like Carly’s integrations page. From there you can wire Shopify to any REST API without waiting for an official connector.
How much does an AI automation for Shopify cost?
With Carly, AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Most Shopify integrations bill separately per app, so the automation layer is a single line rather than a per-connector fee.

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."
