TL;DR

To integrate Weebly with V0 by Vercel, generate a Next.js frontend with V0 and create an API route that fetches your Weebly site content via the Weebly REST API. This headless CMS pattern lets you migrate away from Weebly's limited templates to a custom Next.js frontend while keeping your existing Weebly content — or it enables building a standalone app that queries Weebly site data. Store your Weebly OAuth token in Vercel environment variables.

Weebly as a Headless CMS with a V0 Next.js Frontend

Weebly is a widely used website builder that's been part of Square's portfolio since 2018. While Weebly's drag-and-drop editor is convenient for managing content, its templates are constrained compared to what you can build with Next.js and Tailwind CSS. The Weebly API enables a headless CMS pattern: keep the content management workflow in Weebly (where non-technical staff are comfortable managing it), but replace the Weebly template with a custom Next.js frontend that gives you full design control and better performance.

Weebly's REST API provides access to site data, pages, blog posts, and store products. Authentication uses OAuth 2.0 — you register a Weebly app through their developer portal, go through the OAuth flow, and receive an access token that authenticates API requests. The API returns JSON responses with your site's content structure, which your Next.js API routes proxy and transform for your frontend components.

This integration is particularly valuable for Weebly users who have significant content in their existing site and want to redesign the frontend without migrating all content to a different CMS. By pointing V0-generated Next.js pages at the Weebly API, you get the best of both worlds: Weebly's familiar content management interface for editors, and a modern Next.js frontend with full Tailwind design flexibility.

Integration method

Next.js API Route

V0 generates the Next.js frontend pages. A Next.js API route fetches site content (pages, blog posts, products) from the Weebly REST API using your OAuth access token. The API proxies these requests to Weebly's servers, and your custom Next.js frontend replaces Weebly's template-constrained rendering with full design control.

Prerequisites

  • A Weebly account with a published site and content you want to access via the API
  • A Weebly developer account — register at dev.weebly.com to create an app and get OAuth credentials
  • A Weebly OAuth access token for your specific site — obtained through the OAuth flow documented at dev.weebly.com
  • The site ID for your Weebly site — visible in the Weebly Admin panel URL or via the API
  • A V0 account and Next.js project deployed to Vercel

Step-by-step guide

1

Set Up Weebly Developer App and Get OAuth Credentials

To access the Weebly API, you need to register a developer app in the Weebly developer portal and complete the OAuth flow to get an access token for your site. Navigate to dev.weebly.com and log in with your Weebly account credentials. In the developer portal, click 'Create App' or 'Register an App'. Give your app a name and description — this is your internal reference, not visible to end users. For the OAuth redirect URI, enter your Vercel app's callback URL: https://your-app.vercel.app/api/weebly/callback. For local development, also add http://localhost:3000/api/weebly/callback. After creating the app, you receive a Client ID and Client Secret. These are your OAuth application credentials. To get an access token for a specific site, you need to complete the Weebly OAuth flow: redirect the user to Weebly's OAuth authorization URL with your Client ID, user approves access, Weebly redirects to your callback with an authorization code, and you exchange the code for an access token. For headless CMS use cases where you're accessing your own Weebly site (not building a multi-tenant Weebly app), you can complete the OAuth flow once via a script or manual browser request, get a long-lived access token, and store it as an environment variable. The access token for your own site doesn't expire unless you revoke it or change your Weebly password. This is the simplest approach for a single-site integration. Note your Weebly Site ID as well — it's visible in your Weebly admin URL (the numeric ID in the URL) and is required for all site-specific API calls.

V0 Prompt

Create a CMS content overview page for a Weebly-powered website. Show three content sections side by side: 'Pages' (showing page count and list of page titles), 'Blog Posts' (showing post count and recent post titles with dates), and 'Products' (showing product count). Add a 'Refresh Content' button at the top right that re-fetches from the API. Show a 'Last synced' timestamp.

Paste this in V0 chat

Pro tip: For a single-site headless CMS, complete the OAuth flow manually once in a browser to get the access token, then store it as WEEBLY_ACCESS_TOKEN in Vercel. Weebly's single-site access tokens are long-lived and don't require regular refresh for personal/developer access.

Expected result: A Weebly developer app is registered with the correct redirect URI, and you have a Client ID, Client Secret, Site ID, and Access Token ready to configure in Vercel.

2

Create the Weebly API Routes

Build Next.js API routes that fetch content from the Weebly REST API. Weebly's API base URL is https://api.weeblycloud.com/user/{user_id}/site/{site_id}/ — you need both a user ID and site ID for every request. The user ID can be found via GET /api/auth/me after authentication. For blog posts, the endpoint is GET /user/{userId}/site/{siteId}/blog/{blogId}/post with pagination parameters (page, limit). The response includes post title, body, excerpt, date_created, and author information. You'll need to first get your blog ID via GET /user/{userId}/site/{siteId}/blog. For pages, use GET /user/{userId}/site/{siteId}/page which returns all published pages with their title, URL, and page content. Pages may contain HTML content that you render in your Next.js frontend. For store products (if using Weebly's e-commerce), use GET /user/{userId}/site/{siteId}/store/product. The response includes product name, description, price, images, and SKU information. All API requests require an Authorization header with your access token: Authorization: Bearer {access_token}. The API also requires your User-Agent to be set to 'weebly-developer' or your app name. Cache API responses in your Next.js API routes using next: { revalidate: 300 } to avoid hitting Weebly's API rate limits on every page load.

app/api/weebly/posts/route.ts
1// app/api/weebly/posts/route.ts
2import { NextResponse } from 'next/server';
3
4const WEEBLY_ACCESS_TOKEN = process.env.WEEBLY_ACCESS_TOKEN!;
5const WEEBLY_USER_ID = process.env.WEEBLY_USER_ID!;
6const WEEBLY_SITE_ID = process.env.WEEBLY_SITE_ID!;
7const WEEBLY_BLOG_ID = process.env.WEEBLY_BLOG_ID!;
8const WEEBLY_BASE = 'https://api.weeblycloud.com';
9
10const weeblyHeaders = {
11 Authorization: `Bearer ${WEEBLY_ACCESS_TOKEN}`,
12 'Content-Type': 'application/json',
13 'X-Weebly-Access-Token': WEEBLY_ACCESS_TOKEN,
14};
15
16export async function GET(request: Request) {
17 const { searchParams } = new URL(request.url);
18 const page = searchParams.get('page') || '1';
19 const limit = searchParams.get('limit') || '10';
20
21 const response = await fetch(
22 `${WEEBLY_BASE}/user/${WEEBLY_USER_ID}/site/${WEEBLY_SITE_ID}/blog/${WEEBLY_BLOG_ID}/post?page=${page}&limit=${limit}`,
23 {
24 headers: weeblyHeaders,
25 next: { revalidate: 300 }, // Cache 5 minutes
26 }
27 );
28
29 if (!response.ok) {
30 console.error('Weebly API error:', response.status, await response.text());
31 return NextResponse.json(
32 { error: 'Failed to fetch blog posts' },
33 { status: response.status }
34 );
35 }
36
37 const data = await response.json();
38
39 const posts = (data.data || []).map((post: any) => ({
40 id: post.blog_post_id,
41 title: post.title || 'Untitled',
42 excerpt: post.post_body?.replace(/<[^>]*>/g, '').substring(0, 150) || '',
43 body: post.post_body || '',
44 author: post.author || '',
45 publishedAt: post.date ? new Date(post.date * 1000).toISOString() : null,
46 url: post.url || '',
47 tags: post.tags || [],
48 }));
49
50 return NextResponse.json({
51 posts,
52 total: data.total || posts.length,
53 page: parseInt(page),
54 });
55}

Pro tip: Weebly's API returns Unix timestamps (seconds since epoch) for date fields, not ISO strings. Convert them using new Date(timestamp * 1000).toISOString() in your API route normalization code.

Expected result: GET /api/weebly/posts returns a normalized array of blog posts from your Weebly site with titles, excerpts, authors, and publish dates.

3

Add Weebly Credentials to Vercel Environment Variables

Weebly requires five environment variables: the access token, user ID, site ID, and blog ID (if fetching blog posts). All are server-only — they're used exclusively in API routes and should never be exposed to the browser. To find your Weebly User ID and Site ID, make a test API call to the Weebly API using your access token, or look in your Weebly admin URLs. The Site ID appears in the admin URL as a numeric identifier. Your User ID is your Weebly account ID, available from the API's /auth/me endpoint or your developer portal account page. In Vercel Dashboard → Settings → Environment Variables, create the following server-only variables (no NEXT_PUBLIC_ prefix): WEEBLY_ACCESS_TOKEN, WEEBLY_USER_ID, WEEBLY_SITE_ID, and WEEBLY_BLOG_ID. Select all three scopes for each variable. For local development, add all variables to .env.local. Weebly doesn't have separate sandbox and production environments — all API calls hit the same Weebly servers, so use real credentials carefully during development. Consider creating a separate test Weebly site for development rather than testing against your production site's content. After saving variables in Vercel, trigger a redeployment. Test the API route by visiting /api/weebly/posts in your deployed app — you should see your Weebly blog posts as JSON.

.env.local
1# .env.local
2WEEBLY_ACCESS_TOKEN=your_weebly_oauth_access_token
3WEEBLY_USER_ID=your_weebly_user_id
4WEEBLY_SITE_ID=your_weebly_site_id
5WEEBLY_BLOG_ID=your_weebly_blog_id

Pro tip: Weebly's API rate limits are conservative — about 100 requests per minute. Always add caching (next: { revalidate: 300 }) to your API route fetch calls to avoid hitting rate limits when your pages receive traffic spikes.

Expected result: All Weebly environment variables are configured in Vercel and the /api/weebly/posts endpoint returns real content from your Weebly site.

Build the Weebly Content Frontend with V0

Now connect your V0-generated frontend components to the Weebly API routes. The key decision is whether to render content server-side (static generation or server-side rendering) or client-side. For blog listings and product catalogs, static generation with revalidation (ISR) gives the best performance — the page is pre-rendered at build time and refreshed every few minutes from the Weebly API. For a blog listing page, use a React Server Component that fetches from your /api/weebly/posts route (or directly from the Weebly API in the server component). This renders the blog list as static HTML that loads instantly for users. For individual blog posts, create a dynamic route [slug] that fetches the specific post on demand. Weebly stores blog post body content as HTML — you'll render this HTML in your Next.js component. Sanitize the HTML before rendering it to prevent XSS: use DOMPurify for client-side rendering or a library like sanitize-html for server-side. Wrap the sanitized HTML in a div with Tailwind's prose class from @tailwindcss/typography for automatic article typography styling. For V0, use follow-up prompts to refine the blog layout — adjust typography, add reading time estimates, improve the card grid spacing, and polish the mobile layout. V0 is most effective for this kind of iterative design refinement.

V0 Prompt

Create a blog page that fetches posts from /api/weebly/posts. Show an H1 heading 'Our Blog', then a 3-column grid of post cards. Each card has the post title as a heading, excerpt text, author name, formatted publish date, and a 'Read More' link. Add pagination controls at the bottom (Previous/Next). Show a loading skeleton for 6 cards while fetching. Add a category tag list at the top of the page that filters the visible posts.

5 const baseUrl = process.env.NEXT_PUBLIC_APP_URL || 'http://localhost:3000';
6 const res = await fetch(`${baseUrl}/api/weebly/posts?page=${page}&limit=9`, {
7 next: { revalidate: 300 }, // Revalidate every 5 minutes
8 });
9 if (!res.ok) throw new Error('Failed to fetch posts');
10 return res.json();
11}
12
13export default async function BlogPage({ searchParams }: { searchParams: { page?: string } }) {
14 const page = parseInt(searchParams.page || '1');
15 const { posts, total } = await getBlogPosts(page);
16 const totalPages = Math.ceil(total / 9);
17
18 return (
19 <main className="max-w-6xl mx-auto px-4 py-12">
20 <h1 className="text-4xl font-bold mb-8">Our Blog</h1>
21 <div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
22 {posts.map((post: any) => (
23 <article key={post.id} className="rounded-lg border p-6 hover:shadow-md transition">
24 <h2 className="text-xl font-semibold mb-2">
25 <a href={`/blog/${post.id}`} className="hover:text-blue-600">{post.title}</a>
26 </h2>
27 <p className="text-gray-600 text-sm mb-4">{post.excerpt}...</p>
28 <div className="flex items-center justify-between text-sm text-gray-500">
29 <span>{post.author}</span>
30 <span>{post.publishedAt ? new Date(post.publishedAt).toLocaleDateString() : ''}</span>
31 </div>
32 </article>
33 ))}
34 </div>
35 {totalPages > 1 && (
36 <div className="flex justify-center gap-2 mt-8">
37 {page > 1 && <a href={`?page=${page - 1}`} className="px-4 py-2 border rounded">Previous</a>}
38 <span className="px-4 py-2">Page {page} of {totalPages}</span>
39 {page < totalPages && <a href={`?page=${page + 1}`} className="px-4 py-2 border rounded">Next</a>}
40 </div>
41 )}
42 </main>
43 );
44}

Pro tip: Use Next.js Incremental Static Regeneration (ISR) with revalidate: 300 for Weebly content pages — this pre-renders pages as static HTML for fast loading and automatically re-fetches from Weebly every 5 minutes to keep content fresh, without rebuilding on every request.

Expected result: The blog listing page renders real Weebly blog posts with proper typography, pagination, and a 5-minute content refresh cycle via ISR.

Common use cases

Headless Weebly Blog with Next.js Frontend

Fetch blog posts from a Weebly site and display them in a custom V0-generated blog layout. Blog editors continue using Weebly's familiar editor while the public-facing blog gets a fully customized Next.js design with fast static generation.

V0 Prompt

Create a blog listing page that shows blog post cards fetched from /api/weebly/posts. Each card shows the post title, excerpt (first 150 chars of body), author name, publish date, and a featured image. Include a category filter at the top. Show a sidebar with popular posts and categories. Use a clean editorial layout with generous whitespace.

Weebly Page Content Migration Frontend

Build a Next.js frontend that fetches and renders Weebly page content, maintaining SEO value while upgrading the visual design. The API route fetches page data from Weebly and the Next.js pages render with custom components instead of Weebly's template system.

V0 Prompt

Create a dynamic page template that renders content from /api/weebly/pages/[slug]. Show the page title as an H1, render the page body HTML in a prose container with proper typography. Add a navigation sidebar that lists all site pages from /api/weebly/pages. Include breadcrumb navigation at the top.

Weebly Store Product Catalog

Display Weebly Store products in a custom V0-generated storefront that has better performance, custom filtering, and design flexibility compared to Weebly's native store templates.

V0 Prompt

Create a product catalog page that fetches products from /api/weebly/products. Show products in a 3-column responsive grid. Each card shows the product image, name, price, and an 'Add to Cart' button. Include category filters and a sort dropdown (Price: Low to High, Newest). Show a product count badge in the category filters.

Troubleshooting

Weebly API returns 401 Unauthorized — 'Invalid token' or similar auth error

Cause: The access token has been revoked, expired due to account changes, or the Authorization header format is incorrect.

Solution: Verify the WEEBLY_ACCESS_TOKEN in Vercel environment variables is correct and hasn't been revoked. Check that the Authorization header uses the correct format for the Weebly API — some Weebly API versions use 'X-Weebly-Access-Token' as the header name rather than Bearer token. Try both header formats.

typescript
1// Try both header formats if one doesn't work
2const headers = {
3 'X-Weebly-Access-Token': process.env.WEEBLY_ACCESS_TOKEN!,
4 'Content-Type': 'application/json',
5};

Blog post body HTML renders with broken styling — Weebly styles override the Next.js design

Cause: Weebly injects CSS classes and inline styles in blog post HTML that conflict with Tailwind CSS's reset styles.

Solution: Sanitize and clean the HTML before rendering. Use sanitize-html to strip Weebly's inline styles and class attributes, leaving only semantic HTML. Then apply Tailwind's prose class (from @tailwindcss/typography) to style the content consistently with your design system.

typescript
1// Install: npm install sanitize-html @types/sanitize-html
2import sanitizeHtml from 'sanitize-html';
3
4const cleanHtml = sanitizeHtml(post.body, {
5 allowedTags: sanitizeHtml.defaults.allowedTags.concat(['img', 'h1', 'h2']),
6 allowedAttributes: { 'a': ['href'], 'img': ['src', 'alt'] },
7});
8// Render: <div className="prose" dangerouslySetInnerHTML={{ __html: cleanHtml }} />

API route returns correct data locally but Vercel deployment shows stale content

Cause: Vercel's CDN caches API route responses. If using next: { revalidate: N } in the fetch call, the cache is shared across all instances and may not update as quickly as expected.

Solution: Add cache: 'no-store' to bypass caching for dynamic content, or use the On-Demand Revalidation feature to programmatically revalidate pages when content changes. For a headless CMS, consider setting up a Weebly webhook (if supported) that calls your Vercel revalidation endpoint whenever content is updated.

typescript
1// For always-fresh data in API routes:
2const response = await fetch(weeblyUrl, {
3 headers: weeblyHeaders,
4 cache: 'no-store', // Always fetch fresh data
5});

Best practices

  • Cache Weebly API responses with next: { revalidate: 300 } (5 minutes) — Weebly's rate limits are conservative, and caching prevents hitting them during traffic spikes
  • Sanitize HTML from Weebly's blog post body before rendering with dangerouslySetInnerHTML to prevent XSS vulnerabilities
  • Use Next.js Incremental Static Regeneration for content pages — pre-render for performance, auto-refresh on a schedule to keep content current
  • Normalize Weebly's API response format in your API routes (convert Unix timestamps to ISO strings, strip unnecessary fields) so your frontend components have a clean, predictable data shape
  • Always check the Weebly Developer Portal for your API version's specific requirements — Weebly has made API changes since the Square acquisition, and older documentation may be inaccurate
  • Consider this integration as a migration bridge, not a permanent architecture — Weebly's API has limitations compared to dedicated headless CMS platforms; if long-term, consider migrating content to a platform like WordPress, Contentful, or Sanity
  • Log API errors from Weebly in Vercel function logs with full context (status code, response body, endpoint URL) to diagnose rate limit and authentication issues quickly

Frequently asked questions

Does Weebly have a proper headless CMS mode?

Weebly does not have an official headless mode — it's primarily a template-based website builder. However, their REST API provides enough access to pages, blog posts, and store products to use it as a content source. This is a migration-oriented pattern rather than a purpose-built headless CMS architecture.

How do I get my Weebly access token for the API?

Register a developer app at dev.weebly.com to get a Client ID and Client Secret. Then complete Weebly's OAuth flow: redirect to Weebly's authorization URL, user approves, exchange the code for an access token. For accessing your own site (not building a multi-tenant app), you complete this once, save the token, and use it permanently unless you revoke it or change your password.

Can I update Weebly content from my Next.js app via the API?

Yes — Weebly's API supports creating and updating blog posts and pages via POST/PUT requests. This allows building a custom content editor in your V0 app that writes back to Weebly. However, for most headless setups, content editors still use the Weebly dashboard and the Next.js app is read-only.

What content types does the Weebly API expose?

The Weebly API exposes: site metadata, pages (with HTML content), blog posts (with author, tags, body HTML), blog categories, store products (with images, pricing, variants), store orders, and members (if using Weebly's membership feature). The API does not expose all visual elements from the drag-and-drop builder — only content that was entered through Weebly's structured content fields.

Will the Weebly API continue working after Square acquired Weebly?

The Weebly API has continued functioning after the Square acquisition, though new feature development has been slow. The developer portal remains active at dev.weebly.com. For long-term production use, treat this as a migration path — get your content and redesign your frontend, then consider moving the content management to a platform with more active API development.
