WordPress is the most popular CMS in use today. why? Because you can easily integrate it with thousands of tools to improve your website’s performance and functionality.

Although these tools cover a wide range of industries, users are consistently impressed by the number of tools available for e-commerce. One of the most powerful e-commerce tools is the WooCommerce API.

Understand the WooCommerce API

WooCommerce’s API has three main components. To understand how powerful this API is, let’s look at each component individually.


WooCommerce’s REST API allows users to access your WooCommerce storefront from outside your website. This design makes your store accessible from other internet applications, such as Shopify, for example.

eventually, REST API Easily manage your store. Accessing your WooCommerce store from other apps’ dashboards also gives you access to full WooCommerce management functionality.

Legacy API

Previously, enabling legacy APIs was the way to activate WooCommerce’s APIs. However, this part of the process is becoming obsolete in recent versions.

The latest version is WooCommerce REST API. Integrates directly with WordPress API. Legacy APIs are older versions of WooCommerce. WooCommerce tends to launch legacy APIs by default, so users should double-check their settings.


Webhooks allow WooCommerce to “call” other apps. For example, if you want actions performed in other apps to trigger actions in WooCommerce, you can use webhooks.

The API accomplishes this using URLs. You can send notification alerts to specific URLs through the API. These URLs can trigger events on one site and trigger other actions on another site or page.

WooCommerce API Key Terms

As you read WooCommerce’s API documentation, you’ll come across terms that are specific to WooCommerce. Let’s review these terms and definitions to help you navigate the API process.

Request/response format

This indicates the format that WooCommerce uses to send certain types of data. Being aware of different data types is important because certain URLs and triggers will not work unless the data is received in the proper format.

The standard format for most data within the WooCommerce API is JSON. Calendar dates are returned as integers, and any numbers (amounts, prices, totals, etc.) are included in the text string, defaulting to two decimal places. If left blank, an empty string or “null” will be returned.


The authentication process enables WooCommerce API integration. Users can use API keys to connect APIs to other platforms.

To generate a WooCommerce API key, you need to access your settings. WooCommerce users have two keys available to them: a private key and a consumer key.

Consumer keys are also known as general keys or API keys. These keys are issued to users from various platforms. WooCommerce API keys allow you to connect to other platforms like WordPress, Shopify, and more.

Private keys work similarly for specific apps and platforms. When you connect a third-party tool or app to WooCommerce, the public or consumer key acts as the “username” for your login credentials, and the private key acts as the password.

end point

From an API technology perspective, an endpoint is the point at which an API interacts with another app or platform. Examples of endpoints are URLs for specific platforms such as Shopify or Facebook.

WooCommerce API setup

The process of setting up WooCommerce API is relatively simple. Follow the steps below to link all your tools to your platform and transform your customers’ e-commerce shopping experience.

You need to navigate to the following menu in your WordPress dashboard.

WooCommerce > Settings > Advanced Settings > Legacy API

There is a checkbox that indicates whether the API is enabled. Make sure the checkbox is selected and click Save Changes to enable API access.

How to create an API key in WooCommerce

API keys are the backbone of WooCommerce API functions. Create tools to connect your favorite tools and platforms. To do this, follow the steps below.

1. Add a key

You must create a new key for each app or platform that connects to WooCommerce. The API generates a consumer key and private key for each new connection you create.

To add a key, you need to go to the REST API menu. Here’s how to find it:

WooCommerce > Settings > Advanced Settings > REST API

Once you’re there, click Add key.

2. Configure key settings

[キーの追加]Once you click , you’ll need to make a few decisions. For each key you create, you must configure the following settings:

  • explanation – Now give each key a “name” for the corresponding platform to help organize it.
  • owner – Assign keys to specific users within your team who are responsible for them.
  • authority – These determine what functionality is given to this particular key. For example, if you need a specific key to delete or adjust data, you need to grant it “read/write permissions”.

3. API generation

Once the settings are complete, press the “Generate Key” button at the bottom of the screen. The next page contains the consumer key and private key, as well as his QR code for this connection.

Once you exit the API generation page, you cannot return. Therefore, copy these keys to another Word or Notes document and keep need them to connect to WooCommerce setup.

4. Connect to third-party apps using keys

Now that your API key has been generated, you can start connecting to third-party apps and platforms known as “API clients.” You will need to follow the steps on both sides of the connection between WordPress and the WooCommerce menu in the app of your choice.

Each platform is different, so you will need to access the help resources for that specific platform. Look for tips on how to access app credentials.

Most platforms offer multiple authentication types. We recommend choosing basic authentication.

Copy and paste your general or consumer API key into the Username bar and use your private key as your password. This allows you to connect WooCommerce to any of your other powerful e-commerce tools. The next step is to start making API requests.

How to make a WooCommerce API request

API requests are where the magic happens. These requests enable all the “cool” features that make your life easier. These requests come in two forms: GET or PUT. To configure between tools, follow the steps below.

1. Test the GET request

GET requests, as the name suggests, are useful for retrieving data from other sources. A real e-commerce example is getting a list of WooCommerce products. This requires some technical knowledge, but if you follow the instructions you should be fine.

To run this GET function, you must enter the following URL:

Naturally, you’ll need to enter the URL where it says “Your site.” This GET will retrieve all the data for the products listed in WooCommerce.

The WooCommerce API integration returns this data in JSON format. If done correctly, the platform that connects to WooCommerce will parse this data and convert it into a format that is easy to use for end users.

If you run this GET function and receive a 401 or any other numbered code, it means there is some kind of error. To troubleshoot, you may need to go back or look further at your platform’s help resources. If your GET request is successful, you’ll see a JSON string in the Body section of your dashboard.

2. Test the PUT request

You should also check the PUT request using the data from the GET request from step 1. In this example, assume that the product you are using for this request has a product ID of 101. To perform a GET request, the URL is slightly different.

The process of making this a PUT function instead of a GET is easy.

  • There is a drop-down menu next to the URL field.
  • Select it and change the function from GET to PUT.
  • In the body pane of the dashboard, select the Raw option.
  • Open the Text dropdown menu and select JSON.

Once these steps are complete, you can make your request. An example of using this would be to change the price of product #101. To do this, enter the following text:

"regular_price": "50"

after that,[送信]Click to publish your results to your site.
