Weebly (owned by Square) has a limited REST API primarily designed for its app marketplace and e-commerce features — it is not a general-purpose headless CMS API. For most Bolt.new developers, the practical paths are: using Square's API directly for Weebly store products and orders, or migrating a Weebly site into a Bolt-built React app with Tailwind CSS. This tutorial covers both approaches, with detailed steps for the content migration workflow.
Connecting to Weebly from Bolt.new and the Migration Alternative
Weebly is one of the original consumer website builders, acquired by Square in 2018. The acquisition meant Weebly's e-commerce infrastructure was gradually replaced by Square's payment and catalog systems — a shift that affects how developers integrate with Weebly-powered sites today. Weebly's native REST API is primarily a marketplace API: it was designed for developers building apps and extensions that run inside Weebly's editor, not for external developers querying a Weebly site as a headless CMS. This is an important distinction. If you are looking to use Weebly as a data source for a Bolt.new app the way you might use a headless CMS like Contentful or Ghost, Weebly's API is not designed for that — it does not expose blog posts, page content, or site structure in a developer-friendly way.
For e-commerce data — products, orders, customers, inventory — Weebly stores are now powered by Square's backend. This means you can access a Weebly store's catalog and order data through Square's Catalog API and Orders API, which is significantly more capable than Weebly's own product endpoints. If your goal is to display Weebly store products in a Bolt.new app or build a custom storefront, using Square's API directly is the recommended approach.
For developers who have a Weebly website and want to migrate to a modern React/Next.js stack, Bolt.new is an excellent tool for the rebuild. Export your Weebly site's content (Weebly supports basic CSV export of store data and manual copy/paste of page content), bring the content into Supabase as a simple CMS, and use Bolt's AI to build a modern, faster, more SEO-friendly version of the site. This tutorial walks through both the Square API integration path for Weebly store data and the Weebly-to-Bolt migration approach.
Integration method
Weebly's API serves two audiences: Weebly app marketplace developers (building Weebly plugins) and Square-integrated e-commerce (accessing Weebly store data via OAuth). For Bolt.new developers who have an existing Weebly site, the most practical integration is using Square's API directly for e-commerce data (products, orders, customers), or exporting the Weebly site content and rebuilding it as a modern React application in Bolt. Square's API is far more capable than Weebly's own API for e-commerce use cases.
Prerequisites
- A Square Developer account at developer.squareup.com (free) if you want to access Weebly store data via the Square API
- Your Square access token and location ID from the Square Developer Dashboard (Applications → your app → Credentials)
- A Bolt.new project using Next.js for server-side API routes that keep the Square access token secure
- A Weebly account with an active site if using Weebly's native OAuth API for marketplace-style integrations
- Optional: exported Weebly content (CSV product data, page HTML) for the migration use case
Step-by-step guide
Choose Your Integration Path: Square API or Weebly Native API
Choose Your Integration Path: Square API or Weebly Native API
Before building, decide which integration path matches your goal. This determines everything about the implementation. Path 1 — Square Catalog and Orders API (for e-commerce): If your Weebly site has a store (products, orders, customers), access that data through Square's API. After Square acquired Weebly in 2018, all Weebly store data is stored in Square's backend. This means Square's Catalog API and Orders API are the authoritative source for product and order data on Weebly stores. Square's API is well-documented, actively maintained, and significantly more capable than Weebly's own e-commerce endpoints. You authenticate with a static access token from the Square Developer Dashboard — no OAuth flow required for accessing your own store data. Path 2 — Weebly App API (for marketplace integrations): Weebly's native REST API was designed for developers building apps that run inside Weebly's editor — plugins, themes, and integrations in the Weebly App Center. This API uses OAuth 2.0 and provides access to Weebly site configuration, page structure, members, forms, and products. If you are building a Weebly app marketplace extension, this is your path. For most Bolt.new developers, this is not the right approach. Path 3 — Content Migration (Weebly to Bolt): If you have a Weebly site and want to migrate to a modern stack, export your content, bring it into Supabase, and rebuild in Bolt. This is not technically an 'integration' but is the most common reason developers search for 'Weebly API integration' — they want to move away from Weebly, not build deeper into it. This tutorial focuses on Paths 1 and 3 as they serve the most developers.
Pro tip: Weebly's store backend migrated to Square after the 2018 acquisition. If you are accessing Weebly store data (products, orders, customers), use Square's API at connect.squareup.com — not Weebly's own API. Square's documentation and developer tools are far superior.
Expected result: You have clarity on which integration path fits your use case and can proceed with the Square API or migration approach accordingly.
Set Up Square API Access for Weebly Store Data
Set Up Square API Access for Weebly Store Data
To access your Weebly store's product and order data via Square's API, create a Square Developer account at developer.squareup.com. Click 'Create an application' and give it a name. In the application settings, go to the 'Credentials' section. You will see a Sandbox access token (for testing) and a Production access token (for live store data). Copy the Production access token — this is what you will use in your .env file as SQUARE_ACCESS_TOKEN. You also need your Location ID, which identifies which Square business location your Weebly store belongs to. Find it in the Square Seller Dashboard under Account → Business Locations, or call the /v2/locations API endpoint with your access token. Store both values in your .env file as SQUARE_ACCESS_TOKEN and SQUARE_LOCATION_ID. Because the access token provides full access to your store's data (products, orders, customers, payments), treat it like a password and never expose it in client-side code. All Square API calls must happen in a Next.js API route. The Square API base URL is https://connect.squareup.com and all endpoints require the Authorization: Bearer {access_token} header. Square's responses use a consistent format: successful responses have a top-level object with the resource name as the key (e.g., { catalog_objects: [...] }), and errors have an { errors: [...] } array. Square's catalog uses 'objects' that can be of type ITEM (product), CATEGORY, ITEM_VARIATION (variant/size/color), IMAGE, or MODIFIER. Filtering to type=ITEM in your list call returns the base products.
Set up Square API access for my Bolt.new Next.js app. Create a .env file with SQUARE_ACCESS_TOKEN and SQUARE_LOCATION_ID placeholders. Create lib/square.ts with a squareRequest(endpoint, options) helper function that calls Square's API at https://connect.squareup.com{endpoint} with the Authorization: Bearer header using SQUARE_ACCESS_TOKEN. The helper should throw a descriptive error if the response contains an 'errors' array. Export it as a named export. Create a Next.js API route at app/api/products/route.ts that calls GET /v2/catalog/list?types=ITEM and returns the formatted product list with id, name, description, price (converted from cents to dollars), and image_url.

Number(priceMoney.amount) / 100 : null,47 currency: priceMoney?.currency,48 };49 });5051 return NextResponse.json({ products });52}Pro tip: Square's Catalog API returns price in the smallest currency unit — cents for USD. Always divide by 100 when displaying prices. A product priced at $29.99 is stored as 2999 in Square's API. The Square-Version header pins your API to a specific date version, protecting your app from breaking changes in future Square API updates.
Expected result: The /api/products route returns your Weebly store's product catalog formatted with human-readable prices. Products display correctly in the Bolt preview environment.
Migrate Weebly Content to Supabase for a Full Site Rebuild
Migrate Weebly Content to Supabase for a Full Site Rebuild
If your goal is to migrate away from Weebly entirely — rebuilding the site in Bolt with modern React/Tailwind — the process involves extracting your content, structuring it in Supabase, and generating the new site with Bolt's AI. Weebly does not offer a comprehensive content export, but you have a few options. For store products: in your Weebly/Square dashboard, you can export product data as CSV from the Square Item Library. This CSV includes product names, descriptions, prices, SKUs, and images. For blog posts: Weebly does not have a bulk blog export. You must copy blog post content manually or use a scraping approach — use a browser extension or simple script to extract page HTML. For static pages: copy the page content from Weebly's editor and paste it into structured data in Supabase. Once you have your content extracted, design a Supabase schema that mirrors your site structure: a pages table for static pages, a posts table for blog content, and a products table if you are moving away from Square as well. Use Bolt's AI to generate the Next.js routes, layouts, and UI components for each content type. The resulting site will be significantly faster than Weebly (no drag-and-drop builder overhead), have better Core Web Vitals, support ISR for content pages, and be fully customizable. During development in Bolt's WebContainer, the Supabase integration works fine for data fetching and display — outbound calls to Supabase's API are fully supported.
Build a complete Weebly site migration in my Next.js Bolt.new app using Supabase as the CMS. Create Supabase tables: pages (id, title, slug, content_html, meta_description, published_at, is_published) and posts (id, title, slug, excerpt, content_html, featured_image_url, published_at, tags text[], is_published). Build these routes: /[slug] (dynamic static pages with ISR), /blog (paginated post list), /blog/[slug] (post detail with ISR). Each page should have proper HTML meta title, meta description, and Open Graph tags. Use Tailwind CSS for styling. Build a simple /admin page (password-protected with an env var PASSWORD) where I can create and edit pages and posts using a textarea for HTML content.

Use Tailwind's prose plugin (from @tailwindcss/typography) for the article body — it applies clean typographic styles to arbitrary HTML without needing to modify Weebly's markup.
Expected result: A fully functional Next.js blog and page structure is live, with content stored in Supabase. ISR ensures pages are fast and automatically regenerated when content is updated.
Common use cases
Display Weebly Store Products in a Bolt App
Pull product catalog data from a Weebly-powered store and display it in a custom Bolt.new storefront with better UI, filters, and performance than Weebly's built-in themes. Use Square's Catalog API since Weebly stores run on Square's backend after the 2018 acquisition.
Build a product catalog page that fetches products from the Square Catalog API. Create a Next.js API route at app/api/products/route.ts that calls GET https://connect.squareup.com/v2/catalog/list with SQUARE_ACCESS_TOKEN from environment variables. Filter to items of type ITEM. Display products in a responsive grid with photo, name, price (convert from cents to dollars), and description. Add category filtering using the CATEGORY type from the catalog. Include a product detail modal.

Migrate a Weebly Blog to Bolt.new
Rebuild a Weebly blog as a modern Next.js application with ISR, better SEO metadata, and faster load times. Export blog post content from Weebly, store it in Supabase, and build a performant blog with proper Open Graph tags, structured data, and a custom design in Bolt.
Build a blog CMS migration from Weebly. Create a Supabase table 'posts' with columns: id, title, slug, content (rich text as HTML), excerpt, featured_image_url, published_at, tags (text array), is_published (boolean). Build a blog list page at /blog with cards for each published post (title, excerpt, image, date). Build a post detail page at /blog/[slug] with ISR revalidation of 3600 seconds. Add proper SEO meta tags including Open Graph and a JSON-LD Article schema. Include a simple admin form to create and edit posts.

Custom Order Dashboard for a Weebly Store
Build an internal order management dashboard that pulls Weebly store orders via the Square Orders API — showing order status, customer details, line items, and fulfillment information in a cleaner interface than Weebly's default admin panel.
Build an order management dashboard for a Weebly/Square store. Create a Next.js API route that fetches orders from the Square Orders API (POST to /v2/orders/search with location_id from SQUARE_LOCATION_ID env var). Display orders in a table with: order ID, customer name, email, order date, total (in dollars), status, and line items. Add filtering by status (OPEN, COMPLETED, CANCELED). Click an order to expand its line items. Color-code status badges.

Troubleshooting
Square API returns 401 Unauthorized when fetching Weebly store products
Cause: The SQUARE_ACCESS_TOKEN is incorrect, has expired, or was copied from the Sandbox credentials instead of the Production credentials in the Square Developer Dashboard.
Solution: Go to developer.squareup.com → your application → Credentials → Production tab. Copy the Production access token (not Sandbox). Update your .env file and Netlify environment variables. Square Production tokens do not expire but can be revoked — if revoked, generate a new one.
Square Catalog API returns an empty products array even though products exist in the Weebly store
Cause: The catalog objects are returned with pagination — if the store has more than the default page size, additional items are on subsequent pages. Alternatively, the items may be in a different catalog scope (the API may require a specific location filter).
Solution: Check the Square Catalog API response for a cursor field — if present, make additional requests with ?cursor={cursor} to get subsequent pages. Also try adding the location_ids parameter to filter catalog objects to your specific Weebly store location.
1// Handle Square API pagination2async function getAllCatalogItems() {3 const items = [];4 let cursor: string | undefined;5 do {6 const url = cursor7 ? `/v2/catalog/list?types=ITEM&cursor=${cursor}`8 : '/v2/catalog/list?types=ITEM';9 const data = await squareRequest<{ objects: unknown[]; cursor?: string }>(url);10 items.push(...(data.objects || []));11 cursor = data.cursor;12 } while (cursor);13 return items;14}Migrated blog content from Weebly displays with broken styles and unexpected HTML entities
Cause: Weebly's editor produces HTML with inline styles, proprietary class names, and sometimes incorrectly encoded HTML entities. When rendered in a React app, some characters appear as & or instead of & or a space.
Solution: Use the dangerouslySetInnerHTML pattern with Tailwind's prose classes to handle arbitrary Weebly HTML. For HTML entity issues, run the content through a DOMParser or use a library like 'he' to decode HTML entities before storing in Supabase.
1// Clean Weebly HTML before storing in Supabase2function cleanWeeblyHtml(html: string): string {3 // Remove Weebly's inline styles and class names4 return html5 .replace(/\s*style="[^"]*"/g, '') // Remove inline styles6 .replace(/\s*class="wsite-[^"]*"/g, '') // Remove Weebly classes7 .replace(/ /g, ' ') // Fix non-breaking spaces8 .trim();9}Best practices
- Use Square's Catalog API directly for Weebly store data rather than Weebly's own API — Square's API is better documented, more capable, and the canonical source for Weebly store data after the 2018 acquisition
- Store SQUARE_ACCESS_TOKEN in .env (development) and Netlify/Vercel environment variables (production) — never expose it in client-side code
- When migrating Weebly content, use Supabase for the CMS backend and enable ISR with revalidate: 3600 for content pages — this gives you static performance with dynamic content updates
- Use Tailwind's @tailwindcss/typography prose plugin for migrated Weebly HTML content — it handles arbitrary HTML styling without modifying the source content
- Handle Square API pagination for stores with large catalogs — the cursor field in the response indicates additional pages of results
- Test Square API calls in the Bolt preview using Sandbox credentials before switching to Production credentials — outbound calls to Square's API work fine in Bolt's WebContainer
Alternatives
WordPress has a comprehensive REST API that makes it a far better headless CMS for Bolt.new than Weebly — WordPress is the world's most popular CMS with extensive developer tooling and a mature REST API.
Ghost is a modern headless CMS purpose-built for content-focused websites — its Content API is simpler and more developer-friendly than Weebly's limited API, making it a better backend for Bolt.new blogs.
WooCommerce on WordPress provides a mature e-commerce REST API — a better choice than Weebly for headless e-commerce if you want comprehensive product, order, and customer management via API.
Square's API is the recommended path for accessing Weebly store e-commerce data, since Weebly's store runs on Square's backend after the 2018 acquisition — more powerful than Weebly's own API.
Frequently asked questions
Does Weebly have a REST API for accessing site content?
Weebly has a REST API, but it is primarily designed for Weebly App Center marketplace developers building plugins and extensions that run inside Weebly's editor. It is not a general-purpose headless CMS API. The API provides access to site structure, pages, members, forms, and products, but is not suitable for using Weebly as a content backend for an external React application.
How do I access Weebly store products from a Bolt.new app?
Since Square acquired Weebly in 2018, Weebly store data lives in Square's backend. Use Square's Catalog API (GET /v2/catalog/list?types=ITEM) with your Square access token to fetch products. Create a free Square Developer account at developer.squareup.com and get a production access token from your application credentials. This is significantly more capable than Weebly's own product API.
Can I use Weebly as a headless CMS with Bolt.new?
Technically possible through Weebly's API, but not recommended. Weebly's API was not designed for headless CMS use and does not expose content in a structured, developer-friendly format. For a proper headless CMS with Bolt.new, consider Ghost, Contentful, or a Supabase-backed custom CMS. If you already have a Weebly site, migrating the content to Supabase and rebuilding in Bolt is usually faster than working around Weebly's API limitations.
How do I migrate my Weebly site to a Bolt.new app?
Export store products as CSV from the Square Item Library. Copy blog posts and page content from Weebly's editor — there is no bulk export for page content. Store the content in a Supabase database (posts and pages tables). Use Bolt's AI to build the Next.js routes, layouts, and UI components matching your Weebly site structure. The resulting app will be faster, more customizable, and better for SEO than the Weebly-hosted version.
Do Square API calls work in Bolt's WebContainer during development?
Yes. Bolt's WebContainer can make outbound HTTP calls to Square's API from Next.js API routes. Test with Square Sandbox credentials during development in the Bolt preview, then switch to Production credentials after deploying to Netlify or Vercel. The WebContainer limitation only affects incoming connections (webhooks) — outbound API calls work normally.
