Types of WordPress E-Commerce APIs

WordPress provides several e-commerce API types that can be utilized to build a feature-rich online store. Here are the primary types of WordPress e-commerce APIs you should know about:

1. WooCommerce REST API

The WooCommerce REST API is a powerful feature that enables developers to interact with WooCommerce data. It allows you to manage products, orders, customers, coupons, and other critical e-commerce data programmatically. This API supports both GET and POST methods, which are used for retrieving and creating data, respectively.

Key Features of WooCommerce REST API:

• Retrieve and update product information such as titles, descriptions, and prices.
• Add, update, or delete orders.
• Access customer data for tracking sales and engagements.
• Implement product variations, taxonomies, and attributes.
• Handle coupons for promotional discounts.

Example Use Case: Retrieve a list of all orders:

GET /wp-json/wc/v3/orders

2. WordPress REST API for E-Commerce

The WordPress REST API extends beyond WooCommerce and allows you to interact with WordPress core functionality and custom post types. With this API, developers can create custom post types for products, manage stock, and build custom endpoints to cater to specific needs.

Key Features of WordPress REST API for E-Commerce:

• Extend WordPress core features for managing custom product post types.
• Create, read, update, and delete data associated with e-commerce functionalities.
• Build and access custom endpoints for specific e-commerce actions.

Example: Create a custom product post type:

function create_custom_product_post_type() {
    register_post_type('custom_product', [
        'labels' => [
            'name' => 'Custom Products',
            'singular_name' => 'Custom Product',
        ],
        'public' => true,
        'has_archive' => true,
        'supports' => ['title', 'editor', 'thumbnail'],
    ]);
}
add_action('init', 'create_custom_product_post_type');

3. Payment Gateway APIs

Integrating payment gateways is one of the most critical aspects of WordPress e-commerce development. Payment gateway APIs allow you to connect your online store to services like PayPal, Stripe, Authorize.Net, and other local or international payment providers.

Key Features of Payment Gateway APIs:

• Process credit card transactions securely.
• Integrate alternative payment methods such as Apple Pay or Google Pay.
• Handle refunds, order cancellations, and payment status updates.
• Enable recurring billing for subscription-based businesses.

Example: Integrating Stripe for payments:

POST /wp-json/stripe/v1/charge
{
  "amount": 1000,
  "currency": "USD",
  "source": "tok_visa"
}

4. Shipping API Integration

Shipping APIs enable seamless integration with shipping carriers such as UPS, FedEx, DHL, and USPS. These APIs provide real-time shipping rates, tracking, and label generation. This is especially helpful for e-commerce businesses offering physical products with varying shipping methods.

Key Features of Shipping API Integration:

• Calculate real-time shipping rates for customers based on location and weight.
• Generate shipping labels directly from your WordPress dashboard.
• Track shipment status from order placement to delivery.

Example: Retrieve real-time shipping rates using the USPS API:

GET /api/usps/rates?zipcode=90210&weight=1.5

5. Inventory Management API

The inventory management API helps e-commerce stores automate stock updates, manage product quantities, and maintain a smooth ordering process. It can be integrated with third-party inventory systems or warehouses for real-time stock tracking.

Key Features of Inventory Management API:

• Update product stock levels automatically when an order is placed.
• Synchronize stock with external warehouses or inventory systems.
• Alert for low stock levels to avoid product unavailability.

Example: Update stock quantity programmatically:

$product = wc_get_product($product_id);
$product->set_stock_quantity($new_quantity);
$product->save();

6. Customer Relationship Management (CRM) APIs

CRM APIs integrate e-commerce sites with third-party CRM systems like HubSpot, Salesforce, or Zoho. This integration helps businesses track customer behavior, segment audiences, and create personalized marketing strategies.

Key Features of CRM APIs:

• Sync customer data from the e-commerce store to the CRM system.
• Create customer profiles based on purchase history and behavior.
• Automate marketing campaigns and customer communications.

Example: Add customer to CRM using HubSpot API:

POST /contacts/v1/contact
{
  "properties": [
    {"property": "email", "value": "customer@example.com"},
    {"property": "firstname", "value": "John"},
    {"property": "lastname", "value": "Doe"}
  ]
}
