## TL;DR

To integrate WooCommerce with V0 by Vercel, generate a Next.js storefront with V0, create API routes that call the WooCommerce REST API using consumer key and secret credentials, and deploy to Vercel. Your V0-generated app can display products, manage cart state, process orders, and fetch customer data from any WooCommerce store acting as a headless backend.

## Build a WooCommerce Headless Storefront with V0 and Next.js

WooCommerce powers over 6 million online stores worldwide, and its REST API makes it an excellent headless e-commerce backend for Next.js frontends. The 'headless' approach separates the WooCommerce WordPress backend (which handles product management, inventory, payments, and order fulfillment) from the customer-facing storefront (which you build with V0 and Next.js). This gives you full control over the shopping experience design, performance, and user experience while leveraging WooCommerce's mature e-commerce infrastructure.

The WooCommerce REST API v3 covers all the resources you need for a complete storefront: products (with variations, images, attributes, categories), product categories, orders, customers, coupons, and shipping zones. Authentication uses consumer keys — a consumer key and consumer secret pair generated in the WordPress admin — which are passed as Basic Auth credentials or as query parameters. For server-side API routes on Vercel, storing these credentials in environment variables and sending them in the Authorization header as Base64-encoded Basic Auth is the most secure approach.

For V0-generated storefronts, the most common integration pattern is a four-page store: product catalog page (fetching WooCommerce products with filtering by category), single product page (fetching product details, variations, and images), cart page (client-side cart state stored in localStorage or a server session), and checkout (which redirects to WooCommerce's native checkout or integrates a custom payment flow). For simple stores, Vercel's edge caching with ISR (Incremental Static Regeneration) can serve product pages extremely fast while keeping product data fresh from WooCommerce.

## Before you start

- A WordPress site with WooCommerce installed and at least some products added — WooCommerce is free at woocommerce.com and installs as a WordPress plugin
- WooCommerce REST API consumer key and secret — generated in WordPress admin → WooCommerce → Settings → Advanced → REST API → Add Key (set permissions to Read/Write)
- Your WordPress site URL (e.g., https://yourstore.com) — the WooCommerce REST API is at yourstore.com/wp-json/wc/v3/
- HTTPS enabled on your WordPress site — WooCommerce REST API requires HTTPS for authentication (HTTP is allowed only in development with Basic Auth over insecure connections, which WooCommerce warns against)
- A V0 account at v0.dev and a Vercel account for deployment

## Step-by-step guide

### 1. Generate the Storefront UI with V0

Open V0 at v0.dev and describe the e-commerce storefront layout you want to build. WooCommerce products have rich data: name, description, short_description, images array, price, regular_price, sale_price, stock_status, categories, tags, attributes, and variations. Describing the product card and product detail layouts specifically helps V0 generate components that map naturally to WooCommerce's data model. For a product catalog, specify the information shown on each product card (image, name, price, rating, Add to Cart button), how sale prices appear (crossed-out regular price next to red sale price), and how out-of-stock items are displayed (grayed out, 'Notify Me' button). For category filtering, describe whether you want a sidebar with checkboxes, tabs across the top, or a dropdown selector. For the cart, describe whether it's a slide-out drawer or a dedicated cart page — slide-out drawers are more common for modern e-commerce. Ask V0 to generate the cart state management using React context or localStorage-based state — this client-side cart accumulates items before sending the order to WooCommerce. Specify the API endpoints the components will call: GET /api/woocommerce/products for the catalog, GET /api/woocommerce/products/{id} for details, and POST /api/woocommerce/orders for order creation. After generating the UI, use V0's Git panel to push to your GitHub repository.

**Expected result:** A complete e-commerce storefront UI renders in V0's preview with product grid, category navigation, cart drawer, and all interactive states. The components are wired to call /api/woocommerce/products and /api/woocommerce/cart endpoints.

### 2. Create WooCommerce API Routes

Create Next.js API routes that proxy requests to your WooCommerce store's REST API. The WooCommerce REST API base URL is https://yourstore.com/wp-json/wc/v3/ and authentication uses HTTP Basic Auth with your consumer key as the username and consumer secret as the password. Encode both as Base64 (consumerKey:consumerSecret) and pass as the Authorization: Basic {base64} header. The most important routes for a storefront are: GET /products (with query parameters per_page, page, category, status, orderby, order, search, on_sale, stock_status), GET /products/{id} for single product details, GET /products/categories for category listings, POST /orders for creating orders with line items, customer billing, and shipping address, and GET /orders/{id} to check order status. WooCommerce's product response includes an images array (each image has src and alt fields), an attributes array (for variations like size and color), a variations array of IDs (fetch each variation via GET /products/{id}/variations/{var_id}), and a categories array. For the product catalog, use per_page (up to 100) and page parameters for pagination. The category filter uses the category parameter which accepts a category ID — fetch available categories from GET /products/categories first. All WooCommerce API responses include standard HTTP status codes and JSON error messages in a code/message format for error handling.

```
// app/api/woocommerce/products/route.ts
import { NextRequest, NextResponse } from 'next/server';

function getWCAuthHeader(): string {
  const key = process.env.WC_CONSUMER_KEY;
  const secret = process.env.WC_CONSUMER_SECRET;
  if (!key || !secret) throw new Error('WooCommerce credentials are not configured');
  return `Basic ${Buffer.from(`${key}:${secret}`).toString('base64')}`;
}

function getWCBase(): string {
  const storeUrl = process.env.WC_STORE_URL;
  if (!storeUrl) throw new Error('WC_STORE_URL is not configured');
  return `${storeUrl.replace(/\/$/, '')}/wp-json/wc/v3`;
}

async function wcRequest(path: string, options: RequestInit = {}) {
  const response = await fetch(`${getWCBase()}${path}`, {
    ...options,
    headers: {
      Authorization: getWCAuthHeader(),
      'Content-Type': 'application/json',
      ...((options.headers as Record<string, string>) || {}),
    },
  });

  if (!response.ok) {
    const error = await response.json().catch(() => ({}));
    throw new Error(error.message || `WooCommerce API error ${response.status}`);
  }

  return response.json();
}

export async function GET(request: NextRequest) {
  const { searchParams } = request.nextUrl;

  const params = new URLSearchParams({
    per_page: searchParams.get('per_page') || '12',
    page: searchParams.get('page') || '1',
    status: 'publish',
  });

  const passthroughParams = ['category', 'search', 'orderby', 'order', 'on_sale', 'featured', 'stock_status'];
  passthroughParams.forEach((param) => {
    const value = searchParams.get(param);
    if (value) params.set(param, value);
  });

  try {
    const products = await wcRequest(`/products?${params.toString()}`);

    const sanitized = products.map((p: Record<string, unknown>) => ({
      id: p.id,
      name: p.name,
      slug: p.slug,
      price: p.price,
      regularPrice: p.regular_price,
      salePrice: p.sale_price,
      onSale: p.on_sale,
      stockStatus: p.stock_status,
      shortDescription: p.short_description,
      images: ((p.images as Record<string, unknown>[]) || []).slice(0, 5).map((img) => ({
        id: img.id,
        src: img.src,
        alt: img.alt,
      })),
      categories: ((p.categories as Record<string, unknown>[]) || []).map((c) => ({
        id: c.id,
        name: c.name,
        slug: c.slug,
      })),
      averageRating: p.average_rating,
      ratingCount: p.rating_count,
    }));

    return NextResponse.json({ products: sanitized });
  } catch (error) {
    const message = error instanceof Error ? error.message : 'Failed to fetch products';
    return NextResponse.json({ error: message }, { status: 500 });
  }
}
```

**Expected result:** GET /api/woocommerce/products returns a JSON array of sanitized WooCommerce products with IDs, names, prices, images, and categories. Filtering by category using ?category=ID returns only products in that category.

### 3. Implement Cart and Order Creation

Create the order creation API route and connect the cart UI to WooCommerce. The cart in a headless WooCommerce storefront is typically managed client-side in React state or localStorage — it's an array of line items (product ID, quantity, and variation ID if applicable). When the customer is ready to checkout, the cart contents are sent to a Next.js API route that creates a WooCommerce order via POST /orders. A WooCommerce order requires line_items (array of {product_id, quantity, variation_id} objects), billing address, shipping address, and payment_method ('bacs' for bank transfer, 'cod' for cash on delivery, or a payment gateway slug for online payments). The created order is in 'pending' status and returns an order ID, order number, and payment URL. For most headless WooCommerce setups, the payment step redirects to WooCommerce's native checkout page (using the payment link from the created order) or integrates Stripe separately. The simplest approach for V0-built stores is to create the WooCommerce order, then redirect the user to the order's checkout_payment_url for payment processing on the WooCommerce side. More advanced setups integrate Stripe directly in the Next.js frontend and mark the order as paid via the API after successful payment. Test the order creation locally by running npm run dev, adding items to the cart, and completing a test checkout — verify the order appears in WordPress admin → WooCommerce → Orders with the correct line items.

```
// app/api/woocommerce/orders/route.ts
import { NextRequest, NextResponse } from 'next/server';

function getWCAuthHeader(): string {
  const key = process.env.WC_CONSUMER_KEY;
  const secret = process.env.WC_CONSUMER_SECRET;
  if (!key || !secret) throw new Error('WooCommerce credentials are not configured');
  return `Basic ${Buffer.from(`${key}:${secret}`).toString('base64')}`;
}

function getWCBase(): string {
  const storeUrl = process.env.WC_STORE_URL;
  if (!storeUrl) throw new Error('WC_STORE_URL is not configured');
  return `${storeUrl.replace(/\/$/, '')}/wp-json/wc/v3`;
}

export async function POST(request: NextRequest) {
  let body: {
    lineItems: { productId: number; quantity: number; variationId?: number }[];
    billing: Record<string, string>;
    shipping?: Record<string, string>;
    customerNote?: string;
  };

  try {
    body = await request.json();
  } catch {
    return NextResponse.json({ error: 'Invalid request body' }, { status: 400 });
  }

  if (!body.lineItems?.length || !body.billing?.email) {
    return NextResponse.json({ error: 'lineItems and billing.email are required' }, { status: 400 });
  }

  const orderData = {
    payment_method: 'bacs',
    payment_method_title: 'Bank Transfer',
    set_paid: false,
    billing: {
      first_name: body.billing.firstName,
      last_name: body.billing.lastName,
      email: body.billing.email,
      address_1: body.billing.address1,
      address_2: body.billing.address2 || '',
      city: body.billing.city,
      postcode: body.billing.postcode,
      country: body.billing.country,
    },
    shipping: body.shipping
      ? {
          first_name: body.shipping.firstName,
          last_name: body.shipping.lastName,
          address_1: body.shipping.address1,
          city: body.shipping.city,
          postcode: body.shipping.postcode,
          country: body.shipping.country,
        }
      : undefined,
    line_items: body.lineItems.map((item) => ({
      product_id: item.productId,
      quantity: item.quantity,
      ...(item.variationId ? { variation_id: item.variationId } : {}),
    })),
    customer_note: body.customerNote || '',
  };

  try {
    const response = await fetch(`${getWCBase()}/orders`, {
      method: 'POST',
      headers: {
        Authorization: getWCAuthHeader(),
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(orderData),
    });

    if (!response.ok) {
      const error = await response.json();
      throw new Error(error.message || 'Failed to create WooCommerce order');
    }

    const order = await response.json();

    return NextResponse.json({
      orderId: order.id,
      orderNumber: order.number,
      status: order.status,
      paymentUrl: order.checkout_payment_url,
      total: order.total,
    });
  } catch (error) {
    const message = error instanceof Error ? error.message : 'Order creation failed';
    return NextResponse.json({ error: message }, { status: 500 });
  }
}
```

**Expected result:** POST /api/woocommerce/orders with line items and billing data creates a WooCommerce order in 'pending' status and returns the order number and payment URL. The order appears in WordPress admin → WooCommerce → Orders.

### 4. Configure WooCommerce Credentials in Vercel and Deploy

Push your code to GitHub and configure WooCommerce credentials in the Vercel Dashboard. Navigate to Settings → Environment Variables and add three variables: WC_STORE_URL (the full HTTPS URL of your WordPress store, including trailing slash if present — e.g., https://yourstore.com — this is the WordPress site root, not the shop page URL), WC_CONSUMER_KEY (the consumer key starting with 'ck_' — generated in WordPress admin → WooCommerce → Settings → Advanced → REST API → Add Key), and WC_CONSUMER_SECRET (the consumer secret starting with 'cs_' — shown only once when you create the API key, so make sure to copy it at creation time). None should have the NEXT_PUBLIC_ prefix. Set all variables for Production and Preview environments. After saving and redeploying, test by loading your storefront and verifying products appear from WooCommerce. Common deployment issues: if products return 401, verify the consumer key and secret are correct and that the API key has Read/Write permissions. If products return 404, verify WC_STORE_URL is the exact site URL and that WooCommerce is active on that WordPress installation. If you're serving a staging environment, use separate WooCommerce API keys for Production and Preview to avoid test orders appearing in your production WooCommerce. For high-traffic storefronts, add page caching with ISR (export const revalidate = 3600 in product page components) and consider Vercel's Edge Config or Upstash Redis for cart session storage at scale. For enterprise WooCommerce headless implementations requiring advanced features like real-time inventory, RapidDev's team can help design the full architecture.

**Expected result:** The deployed Vercel storefront loads products from your WooCommerce store, category filtering works, product detail pages show correct images and pricing, and test orders appear in the WooCommerce admin after checkout completion.

## Best practices

- Use Next.js ISR (revalidate) for product catalog and category pages — WooCommerce products don't change every second, so serving cached pages from Vercel's edge with background revalidation gives customers the fastest experience
- Sanitize WooCommerce API responses before sending them to the browser — strip internal WordPress fields, user data, and any sensitive pricing metadata that should not be visible to end users
- Never expose WC_CONSUMER_KEY and WC_CONSUMER_SECRET to the browser — always proxy WooCommerce API calls through Next.js API routes with credentials in server-only environment variables
- Create separate WooCommerce API keys for Production and Preview environments — this prevents test orders from Preview deploys appearing in your production order management
- Implement pagination correctly using WooCommerce's X-WP-TotalPages response header to know how many pages of products exist, rather than fetching until you get an empty array
- Cache WooCommerce product categories in memory or Upstash Redis since categories change infrequently — fetching categories on every page load adds unnecessary API calls to your WordPress server
- Add rate limiting to your WooCommerce API routes if your storefront has high traffic — WooCommerce doesn't have a documented rate limit, but WordPress servers can be overwhelmed by many concurrent API requests

## Use cases

### Product Catalog Storefront

A fast, visually distinctive product catalog built with V0 that fetches products from WooCommerce, supports category filtering and search, displays product images and pricing, and links to individual product detail pages. The WooCommerce backend handles inventory and pricing while V0's Next.js frontend handles the shopping experience.

Prompt example:

```
Create an e-commerce product catalog page for a clothing store. Include a sticky header with logo, cart icon with item count badge, and navigation links. Below, a sidebar with category filter (All/Tops/Bottoms/Accessories/Sale), price range slider, and in-stock toggle. The main content area shows a product grid with 3 columns on desktop: each product card shows the main image, product name, price (with sale price if on sale), star rating, and an 'Add to Cart' button. Include a sort dropdown (Newest/Price Low-High/Price High-Low/Best Selling). Show a loading skeleton while products load from /api/woocommerce/products. Add pagination at the bottom. Use a clean modern e-commerce aesthetic.
```

### Product Detail Page with Variations

A single product page that fetches a WooCommerce product with all its variations (size, color), displays a gallery of product images, allows variation selection, shows the selected variation's price and stock status, and has an Add to Cart button that stores the item in cart state.

Prompt example:

```
Build a product detail page with: left side showing a main product image with 4 thumbnail gallery images below; right side showing product name as H1, price (strike-through original + red sale price if applicable), star rating with review count, a short description paragraph, color swatches (circular buttons), size selector (S/M/L/XL as toggle buttons), quantity selector (+/-), Add to Cart button (full width, blue), and a wishlist heart icon. Below the fold, show a tabbed section: Description / Specifications / Reviews tabs. The page fetches data from /api/woocommerce/products/{id} and posts to /api/woocommerce/cart. Use a premium retail design.
```

### Admin Order Management Dashboard

An internal operations dashboard that displays WooCommerce orders with their status, customer details, and items — giving your team a custom view of orders without requiring access to the WordPress admin. Supports order status updates and fulfillment tracking.

Prompt example:

```
Build an order management dashboard with a top stats bar showing: Today's Orders, Pending Fulfillment, Total Revenue Today, and Average Order Value. Below, an orders table with columns: Order #, Customer Name, Items Summary, Order Total, Status badge (Pending/Processing/Completed/Refunded with color coding), Date, and Action buttons (View/Fulfill/Refund). Clicking 'View' opens a side panel with full order details: item list with images, shipping address, customer notes, and order timeline. Add status filter tabs at the top and a search by order # or customer name. Fetch from /api/woocommerce/orders. Use a clean operations tool design.
```

## Troubleshooting

### API returns 401 Unauthorized from WooCommerce

Cause: The WC_CONSUMER_KEY or WC_CONSUMER_SECRET is incorrect or the API key has been deleted from WooCommerce settings.

Solution: Navigate to WordPress admin → WooCommerce → Settings → Advanced → REST API and verify the API key exists. If the consumer secret was lost (it's only shown once at creation), delete the existing key and create a new Read/Write key. Update WC_CONSUMER_KEY and WC_CONSUMER_SECRET in Vercel and redeploy. Also verify the key's permissions are set to 'Read/Write' — a Read-only key cannot create orders.

### Products endpoint returns empty array even though products exist in WooCommerce

Cause: Products may be set to draft or private status, or the WooCommerce REST API may not be enabled on the WordPress installation.

Solution: Verify products are published (not draft) in WordPress admin → WooCommerce → Products. Ensure WooCommerce is installed and active on the WordPress site at WC_STORE_URL. Check that the WordPress site has permalinks enabled (WordPress admin → Settings → Permalinks → Post name or custom) — WooCommerce REST API requires non-default permalinks to work.

### HTTPS certificate error when calling WooCommerce API from Vercel

Cause: The WordPress site at WC_STORE_URL has an invalid, expired, or self-signed SSL certificate, causing Node.js's fetch to reject the connection.

Solution: Ensure your WordPress site has a valid SSL certificate (Let's Encrypt is free and widely supported). Verify the certificate is valid by opening your WC_STORE_URL in a browser — if you see a certificate warning, that's the issue. If you're testing on a local WordPress installation with a self-signed certificate, use ngrok or a local tunnel to expose it with a valid certificate before testing.

### Product images return 403 Forbidden when displayed in the Next.js app

Cause: The WordPress site's media server or CDN is blocking requests from Next.js's image optimization service, or the images require authentication to access.

Solution: In your next.config.js, add your WordPress site domain to the images.remotePatterns configuration to allow Next.js Image Optimization to fetch images from that domain. If images are still blocked, configure your WordPress site's server to allow cross-origin requests from your Vercel deployment domain.

```
// next.config.js
module.exports = {
  images: {
    remotePatterns: [
      { protocol: 'https', hostname: 'yourstore.com', pathname: '/wp-content/**' },
    ],
  },
};
```

## Frequently asked questions

### Do I need to install any WordPress plugins to use the WooCommerce REST API?

No additional plugins are required — the WooCommerce REST API v3 is built into WooCommerce itself and enabled by default. You only need WooCommerce installed and active, pretty permalinks enabled in WordPress settings (Settings → Permalinks → any option other than 'Plain'), and an API key generated in WooCommerce settings. The WooCommerce REST API is available at yoursite.com/wp-json/wc/v3/.

### How do I handle WooCommerce product variations (sizes, colors)?

Product variations are returned as an array of variation IDs in the parent product's variations field. Fetch each variation's details via GET /products/{product_id}/variations/{variation_id} to get variation-specific pricing, stock status, and attribute values. For a size and color picker, fetch all variations at once using GET /products/{product_id}/variations with per_page=100 and display the attribute options. When a customer adds a variation to cart, pass both the product_id and the variation_id to the order creation API.

### Can I use WooCommerce's native payment processing (Stripe, PayPal) with a headless Next.js frontend?

The simplest approach is to redirect to WooCommerce's native checkout_payment_url after creating the order via the API — this handles all payment processing on the WooCommerce side without custom payment integration. For a fully custom payment experience in Next.js, integrate Stripe directly in the frontend using Stripe Elements, then mark the WooCommerce order as paid via the API (PUT /orders/{id} with status: 'processing') after Stripe confirms payment.

### How do I keep product inventory in sync between WooCommerce and my Next.js storefront?

WooCommerce supports webhooks — configure a webhook in WordPress admin → WooCommerce → Settings → Advanced → Webhooks that fires on 'Product updated' and posts to your Vercel API route. When a product's stock changes in WooCommerce, the webhook triggers a cache invalidation in your Next.js app via on-demand ISR (calling res.revalidate('/products/[slug]')). For real-time stock, add stock_status and stock_quantity to your product API responses and display 'Only X left' badges based on the live data.

### What's the difference between WooCommerce's consumer key authentication and WordPress application passwords?

WooCommerce consumer keys (ck_/cs_) are WooCommerce-specific and only work with the WooCommerce REST API at /wp-json/wc/v3/. WordPress application passwords work with the WordPress REST API (/wp-json/wp/v2/) for managing posts, pages, and media. For WooCommerce store data (products, orders, customers), use WooCommerce consumer keys. If you also need to manage WordPress content (blog posts, pages) from the same Next.js app, you'd use both authentication types for their respective APIs.

### How do I implement product search in a headless WooCommerce storefront?

The WooCommerce product search endpoint is GET /products?search=KEYWORD — it searches product names and descriptions. For basic search, this works well for small catalogs. For larger stores (1000+ products), the native WooCommerce search can be slow because it queries MySQL directly. Consider adding Algolia or Elasticsearch for production search, using a WooCommerce plugin that integrates with these services while keeping the headless frontend architecture.
