WooCommerce Shopify Integration: Sync, Migrate or Run Both

You can integrate WooCommerce and Shopify by syncing products, stock, orders or customers between the two stores, using an automation tool such as Zapier for simple one way flows, a connector app for ongoing sync, or a custom integration built on both platforms' APIs. Most businesses do this either to run both platforms side by side for a period, or as a step in moving from one to the other.

Before building anything, it is worth asking whether you need two platforms at all. This guide covers when an integration makes sense, the three main methods, how to plan the data mapping, and how to import WooCommerce products into Shopify if you are migrating.

WooCommerce and Shopify in brief

WooCommerce

An open source ecommerce plugin for WordPress. You host it yourself, own the code and data, and can customize almost anything through plugins or development. It pairs naturally with WordPress content, which makes it popular for stores that publish a lot. The trade off is that you manage hosting, updates and security.

Shopify

A hosted commerce platform. Hosting, security, checkout and core store features are handled for you, and an app store adds the rest. It is quick to launch and easy for staff to run day to day. Customization happens within Shopify's themes, apps and APIs rather than on the server itself.

When integrating the two makes sense

Running two commerce platforms doubles some work, so there should be a clear reason. Common ones include:

• A gradual migration. You are moving from WooCommerce to Shopify (or the reverse) and need both live while you switch over.
• Separate brands or markets. One brand or country runs on WooCommerce and another on Shopify, but they share stock from one warehouse.
• Content plus commerce. A content heavy WordPress site sells a few items through WooCommerce while the main catalogue and physical shops run on Shopify with its point of sale.
• An acquisition. A business you bought runs on the other platform and needs to share inventory or reporting before a decision is made.

If none of these apply, consolidating onto one platform is usually simpler and cheaper to run than keeping two in sync.

Method 1: Automation tools such as Zapier

Automation platforms connect apps through triggers and actions. A typical flow is "when a new product is created in WooCommerce, create the same product in Shopify" or "when an order is placed on Shopify, add a row to a spreadsheet and adjust stock in WooCommerce".

How to set up a basic flow

1. Create an account with the automation tool and start a new workflow.
2. Choose WooCommerce as the trigger app and pick an event, such as a new product or new order.
3. Connect WooCommerce using REST API keys generated in the WooCommerce settings under Advanced, REST API, with the minimum permissions the flow needs.
4. Choose Shopify as the action app and pick the action, such as creating a product or updating inventory.
5. Connect Shopify by authorizing the automation tool's app in your Shopify admin.
6. Map the fields: title, description, SKU, price, images and stock.
7. Run a test with one product, check the result in Shopify, then switch the flow on.

Good for: low volume, one direction flows and quick experiments. Not good for: two way stock sync at volume, products with many variants, or anything where a delay or missed event costs you money.

Method 2: Connector and sync apps

Dedicated sync apps and multichannel inventory tools sit between the stores and keep products, stock and orders aligned on a schedule or in near real time. Many also connect marketplaces and accounting software.

When comparing them, check whether sync is one way or two way, how variants are matched (usually by SKU), how often stock updates, how conflicts are handled when both sides change the same product, and what happens to refunds and returns. Read recent reviews and confirm the app is actively maintained, since connectors in this space come and go.

Method 3: Custom API integration

For full control, a developer builds a small middleware service that reads from one platform's API and writes to the other. This is the right choice when you have large catalogues, complex variants, bundles, B2B pricing or an ERP in the loop.

How it works

• Reading WooCommerce data through the WooCommerce REST API, authenticated with API keys, and listening to WooCommerce webhooks for changes.
• Writing to Shopify through the GraphQL Admin API. Shopify marked its REST Admin API as legacy on October 1, 2024, and since April 1, 2025 new public apps must use GraphQL only, according to Shopify's developer documentation. New integrations should be built on GraphQL from the start.
• Handling events with webhooks on both sides so changes sync within seconds, plus a scheduled job that reconciles everything periodically in case an event is missed.
• Respecting rate limits on both APIs by queuing updates and retrying failures.
• Logging every change so you can see what synced, when and why something failed.

Custom work costs more upfront and needs maintenance as both APIs evolve, but it is the only option that fits your rules exactly rather than the other way round.

Comparing the three methods

Planning the integration

Decide what syncs

Products and stock are the usual starting point. Orders, customers, prices, discounts and refunds each add complexity. Only sync what you actually need.

Pick a source of truth

For each type of data, one system should own it. Typically products are edited in one place only, and stock comes from whichever system knows the warehouse count. Two way editing of the same field is where most sync problems start.

Map the data carefully

WooCommerce and Shopify structure products differently. WooCommerce uses attributes and variations, while Shopify uses options with a limit on how they combine. Categories become collections, and custom fields may need Shopify metafields. Write the mapping down before any code or app is configured.

Plan for growth

A method that works for a hundred products may struggle with ten thousand. Consider where order volume and catalogue size will be in a couple of years.

Testing and maintenance

• Test with a copy of real data, including your most complicated products with many variants.
• Place test orders on both stores and confirm stock moves correctly on the other side.
• Test refunds, cancellations and out of stock cases, not just the happy path.
• Monitor sync logs after launch and set alerts for failures.
• Keep plugins, apps and API versions up to date; outdated integrations cause both errors and security risks.

Importing WooCommerce products into Shopify

If the real goal is moving to Shopify, you need a migration rather than a permanent integration. The main options are:

• Shopify's own Store Importer app, which can bring products, customers and orders from WooCommerce exports.
• CSV export and import. Export products from WooCommerce, reformat the file to Shopify's product CSV template, and import it. This works well for simple catalogues.
• Third party migration apps that move products, customers, orders and reviews together.
• A custom migration script for large or complex catalogues, using the same APIs described above.

Whichever route you take, redirect every old WooCommerce product and category URL to its new Shopify address, or you will lose search rankings and links. A planned site migration covers redirects, SEO checks and a cutover plan.
