For integrating with WooCommerce stores via REST API - products, orders, customers, webhooks, and custom extensions.

Prerequisites

Store Requirements

# WooCommerce store must have:
# 1. WordPress with WooCommerce plugin installed
# 2. HTTPS enabled (required for API auth)
# 3. Permalinks set to anything except "Plain"
#    WordPress Admin → Settings → Permalinks → Post name (recommended)

Generate API Keys

1. Go to WooCommerce → Settings → Advanced → REST API
2. Click Add key
3. Set Description, User (admin), and Permissions (Read/Write)
4. Click Generate API key
5. Copy Consumer Key and Consumer Secret (shown only once)

API Basics

Base URL

https://your-store.com/wp-json/wc/v3/

Authentication

// Node.js - Basic Auth (recommended)
const WooCommerceRestApi = require("@woocommerce/woocommerce-rest-api").default;

const api = new WooCommerceRestApi({
  url: "https://your-store.com",
  consumerKey: process.env.WC_CONSUMER_KEY,
  consumerSecret: process.env.WC_CONSUMER_SECRET,
  version: "wc/v3"
});

# Python
from woocommerce import API

wcapi = API(
    url="https://your-store.com",
    consumer_key=os.environ["WC_CONSUMER_KEY"],
    consumer_secret=os.environ["WC_CONSUMER_SECRET"],
    version="wc/v3"
)

Query String Auth (Fallback)

# Only use if Basic Auth fails (some hosting configurations)
curl https://your-store.com/wp-json/wc/v3/products \
  ?consumer_key=ck_xxx&consumer_secret=cs_xxx

---

Installation

Node.js

npm install @woocommerce/woocommerce-rest-api

// lib/woocommerce.ts
import WooCommerceRestApi from "@woocommerce/woocommerce-rest-api";

const api = new WooCommerceRestApi({
  url: process.env.WC_STORE_URL!,
  consumerKey: process.env.WC_CONSUMER_KEY!,
  consumerSecret: process.env.WC_CONSUMER_SECRET!,
  version: "wc/v3",
  queryStringAuth: false, // Set true for HTTP (dev only)
});

export default api;

Python

pip install woocommerce

# lib/woocommerce.py
import os
from woocommerce import API

wcapi = API(
    url=os.environ["WC_STORE_URL"],
    consumer_key=os.environ["WC_CONSUMER_KEY"],
    consumer_secret=os.environ["WC_CONSUMER_SECRET"],
    version="wc/v3",
    timeout=30
)

Pagination Headers

Header	Description
X-WP-Total	Total number of items

Error Handling

import WooCommerceRestApi from "@woocommerce/woocommerce-rest-api";

async function safeApiCall<T>(

): Promise<T> {
  try {
    const response = await operation();
    return response.data;
  } catch (error: any) {
    if (error.response) {
      // API returned an error
      const { status, data } = error.response;

      switch (status) {
        case 400:
          throw new Error(`Bad request: ${data.message}`);
        case 401:
          throw new Error("Invalid API credentials");
        case 404:
          throw new Error("Resource not found");
        case 429:
          // Rate limited - wait and retry
          await new Promise(r => setTimeout(r, 5000));
          return safeApiCall(operation);
        default:
          throw new Error(`API error: ${data.message}`);
      }
    }
    throw error;
  }
}

// Usage
const products = await safeApiCall(() => api.get("products"));

Checklist

Before Integration

• WooCommerce plugin installed and activated
• HTTPS enabled on store
• Permalinks set to non-Plain setting
• API keys generated with appropriate permissions
• Webhook secret configured

Security

• API keys stored in environment variables
• Webhook signatures verified
• HTTPS used for all API calls
• Rate limiting handled

Testing

• Test API connection
• Test product CRUD operations
• Test order creation/updates
• Test webhook delivery
• Test pagination for large datasets

---

Anti-Patterns

• Plain permalinks - API won't work without pretty permalinks
• HTTP in production - Always use HTTPS
• Ignoring rate limits - WooCommerce may throttle requests
• Large single requests - Use pagination for bulk operations
• Storing keys in code - Use environment variables
• Skipping webhook verification - Always verify signatures
