Why Add Product Attributes to REST API?
Product attributes are often crucial for data analysis or integration with external systems, such as inventory management systems, CRM systems, and reporting platforms. By adding them to the REST API response, you can:
* Automate business processes
* Improve integrations with external applications
* Gain a more complete picture of order data in WooCommerce
How Does GET Order REST API Work in WooCommerce?
The WooCommerce REST API allows retrieving information about orders using the endpoint:
/wp-json/wc/v3/orders
By default, the response contains information about the order, such as order ID, customer data, list of products (line_items), and their metadata (meta_data). However, product attributes are not included in these data. We need to add them manually.
Adding Product Attributes to meta_data in REST API
To add product attributes to the GET Order REST API response, we must use the woocommerce_rest_prepare_shop_order hook. This hook allows modifying the data returned by the API.
Steps:
1. Identify the attributes you want to add (e.g., size, color).
2. Use WooCommerce functions to retrieve product attributes.
3. Add data to the REST API response in the meta_data section of line_items.
Example Code PHP
Here is an example code that adds product attributes to the REST API response:
“`php
add_filter(‘woocommerce_rest_prepare_shop_order’, ‘add_product_attributes_to_rest_api’, 10, 3);
function add_product_attributes_to_rest_api($response, $order, $request) {
$data = $response->get_data();
foreach ($data[‘line_items’] as &$line_item) {
$product_id = $line_item[‘product_id’];
$product = wc_get_product($product_id);
if ($product) {
// Retrieving product attributes
$attributes = $product->get_attributes();
$formatted_attributes = [];
foreach ($attributes as $attribute_name => $attribute) {
$formatted_attributes[$attribute_name] = $attribute->get_options();
}
// Adding attributes to meta_data
$line_item[‘meta_data’][] = [
‘key’ => ‘product_attributes’,
‘value’ => $formatted_attributes
];
}
}
$response->set_data($data);
return $response;
}
“`
What Does This Code Do?
* Catches the REST API response for orders using the woocommerce_rest_prepare_shop_order hook.
* For each product in the order, retrieves its attributes using the get_attributes() function.
* Adds attributes to the meta_data section of the response API.
Summary
With these steps, you can enrich the data returned by WooCommerce’s REST API with product attributes. This solution is particularly useful if you’re integrating your store with external applications that require more detailed information about orders.
