What you need

An n8n account and a Shopify app with API access

A client's warehouse system, a supplier's stock feed, a support inbox and a Slack channel: most Shopify stores I work with have at least three tools that need to know when something happens in Shopify. Shopify Flow handles jobs inside Shopify well. When the job crosses several outside systems, needs real branching logic or calls an AI model along the way, I usually build it in n8n.

This guide is a working setup: how n8n fits next to Flow, how to connect it to your store today, the nodes you'll use, example workflows and the mistakes that break them. n8n and Shopify details were checked against both companies' docs and n8n's pricing page on 7 November 2026.

What n8n does for a Shopify store

n8n is a workflow automation tool. A workflow is a chain of nodes: a trigger, then steps that transform data, make decisions and call other services. It has a node for Shopify and hundreds for other apps, plus a general HTTP Request node, code nodes and AI nodes.

The two work well together. On Grow and higher, Flow's Send HTTP request action can post to an n8n Webhook node, so you get Flow's Shopify triggers and n8n's reach in one chain.

n8n Cloud or self-hosted

Self-hosting is free in license terms but not in time: you look after the server, updates, backups and uptime. n8n's docs recommend Docker Compose for production setups. For most store owners, Cloud is the sensible start. Count executions honestly: a workflow triggered by every order runs once per order, so a store with 3,000 orders a month already passes Starter's limit with one workflow.

Connect n8n to Shopify in 2026

n8n's Shopify credential supports three methods: Access token (recommended by n8n), OAuth2, and API key, which n8n marks as deprecated. Its docs tell you to create a custom app in Settings > Apps and sales channels > Develop apps. That instruction is out of date for new apps: Shopify's own docs say admin-created custom apps can't be created any more, and those made before 1 January 2026 keep working as legacy apps.

So the route depends on what you have:

1. You have a legacy custom app. Use n8n's Access Token credential with your shop subdomain (the part before .myshopify.com), the Admin API access token and the app's secret key. Check its scopes include read and write access to orders and products if you'll use the Shopify node fully.
2. You're starting fresh. Create an app in the Dev Dashboard at dev.shopify.com/dashboard: Create app, Start from Dev Dashboard, then on Versions set the scopes, such as read_orders, write_orders, read_products and write_products, and click Release. Install it on your store from the Installs card.
3. Get tokens with the client credentials grant. In n8n, add an HTTP Request node at the start of each workflow that posts your client ID and secret to https://your-store.myshopify.com/admin/oauth/access_token with grant_type=client_credentials. Pass the returned access_token to later nodes in the X-Shopify-Access-Token header.

n8n's OAuth2 credential, with a client ID, client secret and shop subdomain, is the other option, using an app that has n8n's OAuth redirect URL in its allowed redirection URLs. My guide to building a custom Shopify app covers the Dev Dashboard and token rules in more detail.

Build your first workflow: new orders to a sheet and Slack

1. Add the trigger. Create a workflow, add the Shopify Trigger node, choose your credential and pick the topic orders/create.
2. Filter. Add an IF node, for example to keep only orders over a set total or orders with a certain tag.
3. Shape the data. Add an Edit Fields node to keep only what you need: order name, total, customer email, shipping country.
4. Send it on. Add a Google Sheets node to append a row, and a Slack node to post a message on the True branch.
5. Test. Place a test order and check each node's output in n8n's execution view.
6. Activate. Turn the workflow on. The Shopify Trigger registers its webhook with Shopify and removes it when the workflow is deactivated.

The trigger checks the HMAC signature on each webhook against the secret from your credential, and ignores requests that don't match or that arrive with a different topic. Other topics include orders/paid, orders/fulfilled, orders/cancelled, products/update, customers/create, inventory_levels/update, refunds/create and app/uninstalled.

Go beyond the Shopify node with GraphQL

The Shopify node only covers orders and products, and it was written against Shopify's REST Admin API, which Shopify made legacy on 1 October 2024. For customers, metafields, inventory, fulfillments or bulk work, n8n's docs suggest the HTTP Request node. I send GraphQL there:

POST https://your-store.myshopify.com/admin/api/2026-10/graphql.json
X-Shopify-Access-Token: {{ $json.access_token }}
Content-Type: application/json
{"query": "{ orders(first: 10, query: \"fulfillment_status:unfulfilled\") { nodes { name createdAt } } }"}

Pin the API version in the URL and update it on a schedule, since Shopify releases a new version each quarter. GraphQL also returns only the fields you ask for, which keeps executions small.

n8n Shopify workflows worth building

• Orders to a 3PL or ERP. orders/paid triggers a workflow that maps line items and addresses to the other system's format, posts them, and writes the external ID back to an order metafield.
• Supplier stock sync. A schedule trigger reads a supplier's CSV or API every hour, compares stock and updates inventory through GraphQL.
• Review and ticket triage. New reviews or support emails go to an AI node that tags sentiment and topic, then low-star reviews go to a Slack channel with a suggested reply.
• Daily trading digest. Each morning, pull yesterday's orders, refunds and top products into one message for the team.
• Product data drafts. When a product is created with a short description, an AI node drafts a longer one into a metafield for a person to review. Never publish AI copy without a human check.
• B2B order alerts. Orders from a wholesale customer tag go to the account manager with the customer's history attached.

Most of these are a day or two of build time. If you'd rather have them built and documented, my Shopify AI and automation service starts from $600, and the AI automation cost guide explains the price drivers.

Make n8n workflows reliable

• Keep secrets in credentials, never in node fields or code nodes.
• Add an error workflow that emails or messages someone when any production workflow fails.
• Make writes idempotent. Shopify can deliver a webhook more than once. Check whether an order was already sent before sending it again.
• Batch large jobs. Use Shopify's bulk operations or paginate, rather than one API call per product in a loop.
• Log what you send. Store the order ID and the external system's response, so you can answer "did this order reach the warehouse" in seconds.

Common n8n Shopify mistakes

1. Following old credential steps that start in the Shopify admin's Develop apps screen.
2. Pasting a 24-hour token into a saved credential and finding everything broken the next day.
3. Testing only with the test URL. Workflows must be active for the production webhook to receive orders.
4. Underestimating executions on n8n Cloud. One order-triggered workflow uses one execution per order.
5. Doing Flow's job in n8n. Simple tagging inside Shopify is free and visible to staff in Flow.
6. No duplicate check on webhook-driven writes to other systems.

Next steps

Pick one job that today means copying data from Shopify into another tool by hand. Build it as your first n8n workflow, run it next to the manual process for a week, and compare. Once you trust it, switch off the manual step and add the next workflow.

If the integration is business-critical, such as orders to a warehouse, consider whether a small custom app is the better long-term home. My guide on custom apps vs subscriptions helps with that decision.
