Retrieving and Utilizing Product Data with the WooCommerce API

Retrieving product data from your WooCommerce store through the WooCommerce REST API involves both server-side operations using PHP, and client-side implementations with JavaScript.

Backend: Using PHP and cURL for Making GET Requests

Setting Up PHP cURL Request: Use PHP and cURL to securely request product data from your WooCommerce store, ensuring the handling of sensitive API keys is confined to the server side.

$consumerKey = 'your_consumer_key';
$consumerSecret = 'your_consumer_secret';
$url = 'https://yourstore.com/wp-json/wc/v3/products';

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HTTPHEADER, [
    'Authorization: Basic ' . base64_encode($consumerKey . ':' . $consumerSecret)
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl);

Handling the Response: The response is a JSON string containing product data. Now how do you transfer this server-side data to the client-side JavaScript? You can output the JSON directly from the PHP script and then make it accessible to JavaScript. This can be done via inline scripting or by providing an API endpoint that JavaScript can call to retrieve this data.

Frontend: Implementing with JavaScript

Transferring Data to the Frontend: To bridge the gap between PHP and JavaScript, consider these methods:

  • Inline Script: Echo the JSON data within a script tag in your PHP file. For example:
echo "<script>var products = $response;</script>";
  • API Endpoint: Set up a PHP script as an API endpoint. JavaScript can then make a fetch request to this endpoint.

Parsing JSON in JavaScript: With the data now on the client-side, parse and use it in JavaScript.

let products = JSON.parse(response);  // If using inline script, 'response' is already a JSON object

Manipulating DOM: Use JavaScript to dynamically display product data on your website.

products.forEach(product => {
    let productElement = document.createElement('div');
    productElement.innerHTML = `<h2>${product.name}</h2><p>${product.price}</p>`;

Creating Interactive User Interfaces: JavaScript enables the creation of interactive elements, such as filters or search functions, which can dynamically update the display of products.

Alternative: Fetching Data Directly with JavaScript

For certain scenarios like single-page applications, JavaScript (Fetch API or Axios) can be directly used to fetch data from the WooCommerce API. Ensure API keys are securely managed if they are used client-side.

fetch('https://yourstore.com/wp-json/wc/v3/products', {
    headers: {
        'Authorization': `Basic ${btoa('consumerKey:consumerSecret')}`
.then(response => response.json())
.then(products => {
    // Process and display products

By effectively managing the transfer of data from server-side PHP to client-side JavaScript, and ensuring secure handling of sensitive information, you can build a robust and dynamic e-commerce platform using the WooCommerce REST API.

For more details on JavaScript implementations and dynamic front-end development, you might want to explore resources like the MDN Web Docs for JavaScript tutorials and guides. Geekerhub provides practical insights on using PHP and cURL with the WooCommerce REST API. Additionally, the official WooCommerce documentation remains an invaluable resource for understanding the WooCommerce API.

function makeCurlRequest($url, $method, $data = null) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Content-Type: application/json',
        'Authorization: Basic '. base64_encode($consumerKey.':'.$consumerSecret)

    switch ($method) {
        case 'POST':
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
        case 'PUT':
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
        case 'DELETE':
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');

    $response = curl_exec($ch);
    if ($response === false) {
        // Handle error; log or throw exception

    if (is_resource($ch)) {

    return $response;

POST Requests for Creating Products

To add new products to your WooCommerce store, use a POST request. This involves sending product details in the request body to the WooCommerce API endpoint. Here’s an example of how to create a new product using the makeCurlRequest function:

$data = [
    'name' => 'New Product',
    'type' => 'simple',
    'regular_price' => '19.99',
    // Additional product details...

$response = makeCurlRequest('https://yourstore.com/wp-json/wc/v3/products', 'POST', $data);

PUT Requests for Updating Products

Updating existing products in WooCommerce is accomplished through PUT requests. These requests are similar to POST but are targeted at specific product IDs:

$updateData = [
    'regular_price' => '24.99',
    // Other product properties to update...
$product_id = '123'; // Replace with actual product ID
$response = makeCurlRequest("https://yourstore.com/wp-json/wc/v3/products/$product_id", 'PUT', $updateData);

DELETE Requests for Removing Products

To remove products from your WooCommerce store, use DELETE requests. The following example demonstrates how to delete a product by specifying its ID:

$product_id = '123'; // Replace with actual product ID
$response = makeCurlRequest("https://yourstore.com/wp-json/wc/v3/products/$product_id", 'DELETE');
