Quick Summary
A successful WooCommerce store eventually reaches a point where manual work in the dashboard slows things down. Updating products one by one, syncing orders with shipping tools, or handling bulk changes becomes inefficient. That’s where the WooCommerce REST API helps. It provides a direct, reliable way to connect a store to external apps, automation, and scaling.
It allows different systems to communicate with the WooCommerce store using code instead of clicks. Developers use it to build custom apps, while store owners use it to simplify workflows and improve customer experiences beyond standard plugins. From syncing inventory and managing orders to connecting CRMs, ERPs, and marketing tools, the API enables smarter, more flexible eCommerce operations.
In this blog, we’ll discuss WooCommerce REST APIs, generate secure keys, handle authentication, and work with products, orders, and customers. Let’s dive in!
The WooCommerce REST API is built on top of the WordPress REST API framework. It allows external applications to communicate with your WooCommerce store using standard web requests. Instead of manually updating data through the dashboard, you can interact with your store using code.
The API works through common HTTP methods:
All information is exchanged in JSON format, making the API compatible with almost any programming language or platform.
WooCommerce opens up multiple store resources through its API, allowing full control over core eCommerce operations:
Each resource is accessed through an endpoint, which is a standard URL such as:
/wp-json/wc/v3/products
These endpoints enable tools such as Postman, custom scripts, and external apps to interact with your store.
In practice, the REST API becomes essential as a store grows. Businesses use it to sync inventory across platforms, connect shipping or ERP systems, automate order workflows, and build custom dashboards. It allows real-time updates without requiring a login to the admin panel for each change.
The WooCommerce API uses versions so your store stays compatible even as the platform evolves. It also uses secure API key authentication, ensuring only authorized systems can access your store data. Once configured correctly, it helps you scale operations while keeping your data accurate and secure.
Before any app, tool, or custom script can connect to your WooCommerce store, you need to generate API credentials. These keys act like secure access passes, allowing external systems to interact with your store without exposing your admin login.
The WooCommerce REST API uses two credentials for authentication:
These are required to securely send API requests.
Step 1: Open the REST API Settings
Note: In newer WooCommerce versions, the REST API is enabled by default. You don’t need to install or activate anything extra.
Step 2: Create a New API Key
Description: Use a clear name (e.g., Mobile App Integration or Postman Testing).
User: Select the WordPress user who will own this key.
Permissions: Choose access level:
WooCommerce will instantly create your credentials.
Step 3: Save Your Consumer Key & Secret
After generation, you’ll see your Consumer Key and Consumer Secret. Save them
It is recommended to create separate keys for each integration (e.g., one for testing and another for your live application).
Step 4: Test Your API Connection (Recommended)
Before writing code, quickly test your keys using a tool like Postman or cURL.
Example endpoint:
https://yourdomain.com/wp-json/wc/v3/products
In Postman:
If everything is configured correctly, you’ll receive a 200 OK response with JSON data from your store.
When working with API keys, treat them like passwords. Never expose keys in frontend code or public repositories. Store them using environment variables or secure secret managers. Also, make sure to only give the minimum permissions required. Use HTTPS to encrypt requests and create separate keys for different apps so you can revoke access easily if needed.

WooCommerce supports multiple authentication methods, each suited to different use cases, whether you are building internal tools, public apps, or frontend integrations.
This is the default and most commonly used authentication method in WooCommerce. When you generate REST API keys, WooCommerce creates a Consumer Key (CK) and Consumer Secret (CS) that identify your application.
How it works
Best for
Basic Auth is a simple method that uses the API keys as credentials.
How it works
Best for
Always use Basic Auth over HTTPS. Without SSL, credentials can be exposed.
OAuth 1.0a is an older authentication method still supported for compatibility with legacy systems.
How it works
Best for
In modern WooCommerce setups, OAuth is less common because it is more complex than newer methods.
JWT is a modern token-based authentication method popular in advanced setups.
How it works
Best for
Cookie authentication is used when requests come from users already logged into WordPress.
How it works
Best for
This method is not suitable for external applications or third-party integrations.
| Authentication Type | Best Use Case | Security Level Setup | Complexity |
|---|---|---|---|
| API Keys | Server-to-server communication | High | Simple |
| Basic Auth | Testing & internal apps | Medium (HTTPS required) | Simple |
| OAuth 1.0a | Legacy integrations | Medium | Complex |
| JWT | Mobile, headless, public apps | High | Moderate |
| Cookie Auth | Logged-in browser sessions | Medium | Simple |
Be it a simple backend sync or a complex headless application, choosing the right authentication method ensures your store remains both functional and secure.
CRUD stands for Create, Read, Update, and Delete. These are the four basic operations you’ll perform when working with the WooCommerce REST API.
WooCommerce uses structured JSON objects for products, orders, and customers. You send data to an endpoint, and WooCommerce responds with a status code like:
Products are managed through the endpoint:
/wp-json/wc/v3/products
Get All Products (READ)
curl -X GET https://example.com/wp-json/wc/v3/products \
-u consumer_key:consumer_secret
If successful, WooCommerce returns a 200 OK response with a JSON array of products.
Add a New Product (CREATE)
curl -X POST https://example.com/wp-json/wc/v3/products \
-u consumer_key:consumer_secret \
-H "Content-Type: application/json" \
-d '{
"name": "New Product",
"type": "simple",
"regular_price": "19.99",
"manage_stock": true,
"stock_quantity": 50
}'
Important product fields:
If successful, you’ll receive 201 Created along with the new product ID.
Update a Product (UPDATE)
curl -X PUT https://example.com/wp-json/wc/v3/products/123 \
-u consumer_key:consumer_secret \
-H "Content-Type: application/json" \
-d '{
"regular_price": "24.99"
}'
You only need to send the fields you want to change. Everything else remains unchanged.
Delete a Product (DELETE)
curl -X DELETE https://example.com/wp-json/wc/v3/products/123 \
-u consumer_key:consumer_secret \
-d '{"force": true}'
By default, products move to Trash.
Using “force”: true permanently deletes the product.
Orders are managed via:
/wp-json/wc/v3/orders
List All Orders
curl -X GET https://example.com/wp-json/wc/v3/orders \
-u consumer_key:consumer_secret
Get Order by ID
curl -X GET https://example.com/wp-json/wc/v3/orders/456 \
-u consumer_key:consumer_secret
Update Order Status
curl -X PUT https://example.com/wp-json/wc/v3/orders/456 \
-u consumer_key:consumer_secret \
-H "Content-Type: application/json" \
-d '{"status":"completed"}'
Common order statuses:
In real-world automation, updating order status is common when syncing with shipping or ERP systems.
Customers are handled via:
/wp-json/wc/v3/customers
Create a Customer
curl -X POST https://example.com/wp-json/wc/v3/customers \
-u consumer_key:consumer_secret \
-H "Content-Type: application/json" \
-d '{
"email": "john@example.com",
"first_name": "John",
"last_name": "Doe"
}'
Retrieve Customer by ID
curl -X GET https://example.com/wp-json/wc/v3/customers/789 \
-u consumer_key:consumer_secret
Update Customer Information
curl -X PUT https://example.com/wp-json/wc/v3/customers/789 \
-u consumer_key:consumer_secret \
-H "Content-Type: application/json" \
-d '{
"billing": {
"phone": "1234567890"
}
}'
You can update billing, shipping, email, password, and more using the customer object.
When used correctly, CRUD operations allow full control over your WooCommerce store without ever opening the dashboard.
The WooCommerce REST API can be very useful for automation and smarter store management. As your store grows, you need systems that communicate with each other without manual effort. That is exactly where the API proves its value. Below are some practical ways businesses use the WooCommerce REST API every day.
One of the most common use cases is connecting WooCommerce with external tools such as CRMs, ERP systems, accounting software, shipping platforms, and inventory management systems.
Instead of manually exporting CSV files or updating data across multiple systems, the API enables automatic synchronization. When a customer places an order, the details can instantly move to your CRM. Inventory levels can update across warehouses in real time. Shipping tools can receive order data without human input.
From experience, this kind of automation reduces errors, saves hours every week, and gives sales and support teams real-time access to customer data. The result is faster service and better decision-making.
Every business has unique needs. The REST API allows you to extend WooCommerce without modifying its core files. This keeps your store stable while still allowing deep customization.
For example, if you build a custom mobile app or a headless frontend, the API can fetch live product data, customer accounts, pricing, and order information. Any update made in WooCommerce reflects instantly in the app.
This approach helps businesses create unique shopping experiences while maintaining the reliability of the WooCommerce platform. You get flexibility without breaking your store during updates.
The default WooCommerce reports work well for many stores, but growing businesses often need more detailed insights.
Using the REST API, you can pull real-time data and build custom dashboards that show:
Store owners can see live performance metrics tailored to their business goals. For example, if one product category suddenly performs well, marketing budgets can be adjusted immediately. If stock runs low, purchasing decisions can be made faster.
In real-world operations, access to live data often makes the difference between reacting late and acting at the right moment.
Below are the most frequent WooCommerce REST API errors, what causes them, and how to fix them quickly.
This is the most common WooCommerce API error. It means your request reached the server, but authentication failed.
Common causes
How to fix
This error occurs when authentication succeeds but the user lacks permission to access the endpoint.
Common causes
How to fix
This happens when the API request is malformed or includes invalid data.
Common causes
How to fix
A 404 error usually means WooCommerce cannot find the API endpoint.
Common causes
How to fix
This error appears even when credentials are provided. It happens when some servers strip the Authorization header for security reasons.
Quick workaround (testing only)
Pass credentials as query parameters:
?consumer_key=ck_xxx&consumer_secret=cs_xxx
If you see “Could not get any response,” SSL verification may be failing.

Yes, you can use the WooCommerce REST API on a local development environment. However, authentication can be tricky without HTTPS, especially with Basic Auth, which many tools block over plain HTTP. For smoother testing, consider using tools like ngrok to expose your local server securely. Always test in an environment that closely mirrors your production setup.
Yes, WooCommerce allows you to upload product images through the REST API. You can either provide image URLs that the store will fetch or include base64-encoded image data directly in the product JSON. Both methods let you attach multiple images and define which is the main image. Make sure the image paths are publicly accessible if using URLs.
Yes, the WooCommerce REST API can be used safely in production if configured properly. Always use HTTPS to encrypt API requests, and keep your API keys private—never expose them in frontend code. Stick to the principle of least privilege by assigning only the permissions needed. Using authentication methods like JWT can add an extra layer of control and security.
WooCommerce doesn’t have a built-in rate limit, but your hosting provider or server might enforce one to protect resources. If you’re making frequent or high-volume API calls, monitor performance and consider caching repeated requests. For heavy integrations, speak with your host about possible API usage policies or limits at the server level.
First, create a secret “key” in your WooCommerce settings to get permission. Next, use a simple tool or command to request the information you need from the website.
