Connect your Lovable app to the Weebly API by creating a Supabase Edge Function that authenticates with a Weebly OAuth token or API key and fetches site data, pages, and blog posts. Use Weebly integration primarily for migrating content to Lovable — Weebly is a simple drag-and-drop website builder (now part of Square) whose users often want to export their content into a more capable platform.
Migrate Weebly content to Lovable or build alongside a Weebly site
Weebly is one of the original drag-and-drop website builders, now owned by Square and deeply integrated into Square's e-commerce ecosystem. While Weebly makes it easy to create simple websites, founders who started with Weebly often find its limitations frustrating as their needs grow — limited customization, no database capabilities, basic e-commerce features, and difficulty integrating with modern development tools. Migrating from Weebly to a Lovable app is a common growth path.
The Weebly API serves two purposes for Lovable developers: first, as a content migration source — export all existing pages, blog posts, and store data from Weebly into Supabase, where it powers the new Lovable app while the Weebly site continues running. Second, as a live data source — if you cannot immediately migrate the entire site, the Lovable app fetches Weebly content via the API and displays it in a modern interface, with the eventual goal of replacing Weebly entirely.
Weebly's API is less comprehensive than WordPress or Ghost APIs. The Weebly API is primarily designed for third-party app developers building on the Weebly platform (store apps, design apps), not for headless CMS use. Content fetching is possible but the API has limitations: blog post content is returned as HTML with Weebly's proprietary markup, media files are hosted on Weebly's CDN, and page content (not blog posts) is limited to metadata rather than full content blocks. For migration purposes, this is often sufficient — you extract what you can via API and supplement with manual content recreation for the most important pages.
Integration method
Weebly integrates with Lovable through a Supabase Edge Function that authenticates with the Weebly API using a developer API key and OAuth2 for user account access. The Edge Function fetches site content, pages, and blog posts from Weebly and returns them to the React frontend. This integration is most commonly used for content migration — extracting existing Weebly site content into a new Lovable application.
Prerequisites
- A Weebly developer account at dev.weebly.com with an API key and secret
- OAuth2 authorization from the Weebly site owner you want to access (or a developer account with sites created under it)
- Your Weebly site ID (visible in the Weebly admin URL or API responses)
- A Lovable account with an active Lovable Cloud project
Step-by-step guide

Get Weebly API credentials and store in Cloud → Secrets
Weebly's API requires a developer account and application registration. The API is primarily designed for the Weebly App Center (third-party apps that integrate with Weebly sites), so the setup process is oriented toward app development rather than simple API access. To get API credentials: Go to dev.weebly.com and sign in or create a developer account. Click 'Create an App'. Fill in the app details (name, description) — this is just for developer registration, not a published app. After creating the app, you receive a Client ID and Client Secret (for OAuth2) and can configure an API key for basic access. For accessing your own Weebly sites or those of users who authorize your app, Weebly uses OAuth2. For development purposes, you can use your developer account's admin token to access sites owned by that account directly. In Lovable, click '+' next to Preview to open the Cloud panel, then click 'Secrets'. Add: - WEEBLY_CLIENT_ID — your Weebly app's client ID - WEEBLY_CLIENT_SECRET — your Weebly app's client secret - WEEBLY_ACCESS_TOKEN — the OAuth2 access token for the specific site you want to access - WEEBLY_SITE_ID — the numeric Weebly site ID Weebly access tokens are long-lived (they do not expire by default unless revoked). The site ID is visible in the Weebly admin URL: weebly.com/editor/main.php#action=editor&site_id={SITE_ID}
Pro tip: Weebly's API documentation is at developer.weebly.com/rest-api-reference.html. The most useful endpoints for content migration are /user/sites/{siteId}/blogs/{blogId}/posts for blog posts and /user/sites/{siteId}/pages for page metadata.
Expected result: WEEBLY_ACCESS_TOKEN and WEEBLY_SITE_ID are stored in Cloud → Secrets. A test request to https://api.weeblycloud.com/user/USER_ID/site/SITE_ID with the access token returns site information.
Create the Weebly content proxy Edge Function
Create the Weebly content proxy Edge Function
The Weebly API uses Bearer token authentication with the OAuth2 access token. The API base URL is https://api.weeblycloud.com/. The main endpoints for content are: - GET /user/{userId}/site/{siteId}/blog — list blogs on the site - GET /user/{userId}/site/{siteId}/blog/{blogId}/post — list blog posts - GET /user/{userId}/site/{siteId}/blog/{blogId}/post/{postId} — single post - GET /user/{userId}/site/{siteId}/page — list pages - GET /user/{userId}/site/{siteId}/store/product — list products Note that Weebly's API requires a user ID in addition to the site ID. The user ID is the Weebly account ID associated with the site — visible in the Weebly API response for site information as 'user_id'. Blog post responses include: title, body (HTML content), post_url (the Weebly-hosted URL), excerpt, post_date (Unix timestamp), tags, site_id. The body field contains Weebly's rendered HTML including proprietary markup for Weebly elements. For migration, sanitize this HTML and store it in Supabase. For live display, render it with dangerouslySetInnerHTML and DOMPurify sanitization.
Create a Supabase Edge Function at supabase/functions/weebly-proxy/index.ts that calls the Weebly REST API. Read WEEBLY_ACCESS_TOKEN, WEEBLY_USER_ID, and WEEBLY_SITE_ID from Deno.env.get(). Accept a POST request with 'resource' (blog_posts, pages, products), optional 'blogId' string, optional 'page' and 'limit' integers for pagination. Build the appropriate Weebly API URL and call it with 'X-Weebly-Access-Token: {token}' header. Return the response data array with pagination metadata. Include CORS headers.

These do not render correctly outside Weebly. During migration, strip or replace these with standard HTML equivalents.
Expected result: The weebly-proxy Edge Function deploys. A test request with resource='blogs' returns the list of blogs on the Weebly site. A follow-up request with resource='blog_posts' and the blog ID returns the posts array.
Build the migration tool or content display UI
Build the migration tool or content display UI
The primary use case for Weebly integration is migration. Build an admin-only migration dashboard in Lovable that allows an administrator to trigger the content import, track progress, and validate migrated content. For the migration flow: fetch all blog posts from Weebly via the Edge Function (paginating through all pages), transform each post into your Supabase schema (title, body_html, published_at converted from Unix timestamp, slug generated from the title, featured_image_url extracted from the first img tag in the body), and insert them into a Supabase posts table using supabase.from('posts').upsert() with weebly_post_id as the conflict key (so re-running the import does not create duplicates). For images: Weebly hosts post images on its own CDN (uploads.weeblycloud.com). These URLs will continue working as long as your Weebly account is active but will break if the account is deleted. For permanent migration, download each image, re-upload to Supabase Storage, and update the post body HTML to use the new Supabase Storage URLs. For organizations migrating large Weebly sites with complex content, embedded forms, and e-commerce integrations, RapidDev's team can help plan and execute the full data migration strategy including image re-hosting and URL redirect configuration.
Build a Weebly migration admin page at /admin/migrate-weebly. Add a 'Start Migration' button. On click: call the weebly-proxy Edge Function to get the list of blogs, then fetch all blog posts page by page. For each post, transform it: title from post.title, slug from title.toLowerCase().replace(/[^a-z0-9]+/g, '-'), body_html from post.body, published_at from new Date(post.post_date * 1000).toISOString(), excerpt from the first 200 chars of body text with HTML stripped. Insert into Supabase posts table using upsert with weebly_post_id conflict key. Show a progress bar and count: 'Imported {n} of {total} posts'. When complete, show a summary with links to review the imported posts.

Pro tip: Set up Supabase redirect rules or a URL redirect table before decommissioning the Weebly site. Map old Weebly blog post URLs to new Lovable app URLs to preserve any SEO link equity and prevent 404s for users who bookmarked old Weebly URLs.
Expected result: The migration dashboard successfully imports Weebly blog posts into the Supabase posts table. Each post has correct title, slug, body, and publish date. The progress indicator shows real-time import status.
Common use cases
Migrate Weebly blog posts to Supabase for a new Lovable site
A founder has 3 years of blog posts on Weebly and is launching a new product site with Lovable. The migration Edge Function fetches all blog posts from Weebly's API, transforms the content into a clean format, and saves each post to a Supabase posts table with the original publish date, title, excerpt, and sanitized HTML body. The new Lovable site serves content from Supabase while the original Weebly blog can be archived.
Create a migration tool page in the Lovable app. When an admin clicks 'Import from Weebly', call the weebly-migrate Edge Function which fetches all blog posts from the Weebly API and saves them to a Supabase 'posts' table with fields: title, slug, body_html, excerpt, published_at, featured_image_url, weebly_post_id. Show a progress indicator with count of posts imported. After migration completes, show a summary of imported posts with links to preview them in the new blog.

Display live Weebly blog content in a Lovable wrapper
A business is in the process of migrating from Weebly but needs a transitional period where content from Weebly continues to be served through a new Lovable frontend. The Edge Function fetches the latest blog posts from Weebly's API and the Lovable app displays them with custom design and navigation, with Weebly handling content management during the transition.
Build a transitional blog page that fetches posts from the weebly-proxy Edge Function. Display Weebly blog posts in a custom card layout with the Lovable app's design system rather than Weebly's default theme. Show post title, excerpt, featured image, and formatted date. Add a migration status banner at the top of the page for admins: 'This content is being migrated from Weebly. Migration {X}% complete.' Link to the Supabase migration status.

Sync Weebly store products to a Lovable commerce front
A Weebly store owner wants a custom Lovable shopping experience while keeping product management in Weebly/Square. The Edge Function fetches products from Weebly's store API (which routes through Square's Commerce API after the Square acquisition), displays them in a custom product listing, and links to Weebly's hosted checkout for transactions.
Create a product catalog page that fetches products from the Weebly store via the weebly-proxy Edge Function. Display products in a grid with product image, name, price, and description. Add category filtering from Weebly's product categories. Clicking a product shows a detail page with full description and an 'Buy Now' button that redirects to the Weebly store's product page URL for the actual checkout flow.

Troubleshooting
Weebly API returns 401 Unauthorized
Cause: The access token has been revoked, or the X-Weebly-Access-Token header is missing or malformed.
Solution: Re-authorize through the Weebly OAuth flow to obtain a fresh access token. Verify the WEEBLY_ACCESS_TOKEN value in Cloud → Secrets. Also confirm the WEEBLY_CLIENT_ID header is included — some Weebly API endpoints require the client ID alongside the access token.
Blog posts return with body content missing or truncated
Cause: The Weebly API paginates blog post body content and may require additional parameters to include the full body, or the blog post body_html field requires a different API parameter.
Solution: Check the Weebly API documentation for the blog post endpoint. Some Weebly API versions require ?get_tags=1 or ?api_version=2 to include full body content. Also ensure you are calling the single post endpoint (/blog/{blogId}/post/{postId}) for full content rather than the list endpoint which may return truncated versions.
Images from migrated Weebly posts do not load
Cause: Weebly-hosted images use the uploads.weeblycloud.com CDN with URLs tied to the Weebly account. If the source Weebly account is deleted or the subscription lapses, these URLs break.
Solution: During migration, scan post body HTML for img src attributes pointing to uploads.weeblycloud.com, download each image binary, upload to Supabase Storage, and update the src attribute to the Supabase Storage URL. This makes the migrated content independent of Weebly's infrastructure.
Best practices
- Use migration as the primary use case for Weebly integration rather than ongoing live content fetching — Weebly's API is designed for app development, not headless CMS serving, and has limitations that make it unsuitable for production content delivery.
- Use upsert with weebly_post_id as the conflict key when importing posts to Supabase — this makes the migration idempotent so re-running the import updates existing records rather than creating duplicates.
- Re-host all media from Weebly CDN to Supabase Storage during migration — Weebly CDN URLs are tied to your Weebly account and will stop working if you decommission the account.
- Convert Weebly Unix timestamps (post_date field) to ISO 8601 format using new Date(post_date * 1000).toISOString() when storing in Supabase — Weebly uses Unix seconds while Supabase/PostgreSQL expects ISO format.
- Generate URL slugs from post titles during migration rather than using Weebly's post URLs — create 301 redirects from old Weebly URLs to new Lovable app URLs to preserve SEO link equity.
- Sanitize Weebly blog post HTML with DOMPurify and strip Weebly-specific markup before storing — Weebly HTML contains elements like data-weebly-id attributes and embedded widget code that only render within Weebly's platform.
- Test migrated content across multiple post types before decommissioning Weebly — verify posts with images, embedded forms, and multimedia content display correctly in the Lovable app before redirecting users.
Alternatives
Choose WordPress as the target CMS if you need to migrate from Weebly to a more powerful content management platform — WordPress is a significantly more capable CMS than Weebly for ongoing content management.
Choose Ghost as a migration target if your Weebly site is primarily a blog or newsletter — Ghost's publishing platform is purpose-built for content-focused sites and provides a clean upgrade from Weebly.
Choose Contentful as a migration target if you need structured content modeling beyond blog posts — Contentful's content types can model complex structured data that Weebly's flat page structure cannot support.
Frequently asked questions
Can I fully replace Weebly with a Lovable app?
Yes. The migration pattern described in this tutorial exports all Weebly blog posts, pages, and store data into Supabase, builds the equivalent functionality in Lovable, and then redirects the domain from Weebly to the new Lovable app. The process typically takes 1-4 weeks depending on content volume and functionality complexity. Once complete, you can cancel your Weebly subscription since all content and functionality lives in the Lovable app.
Does Weebly's e-commerce integration work with Lovable?
Weebly's e-commerce is now powered by Square (after the 2018 acquisition). For product catalog data, the Weebly/Square API provides product listings. For actual transactions, Square's payment processing is a separate integration. Migrating Weebly e-commerce to Lovable typically involves: importing product data via the Weebly API into Supabase, rebuilding the storefront in Lovable, and connecting a payment processor (Stripe is natively supported in Lovable).
Why is Weebly integration described as a migration tool rather than an ongoing CMS?
Weebly's API was designed for building apps that run within the Weebly platform (like store apps, booking apps), not for headless CMS use. The API lacks features needed for production content delivery: no webhooks for cache invalidation, limited query capabilities, rate limits unsuitable for serving public traffic, and content that includes Weebly-proprietary markup not designed for external rendering. For ongoing content management, migrating to a proper headless CMS (Ghost, WordPress, Contentful) or using Supabase directly is the better long-term architecture.
How do I migrate Weebly's membership and subscriber data?
Weebly/Square membership and subscriber data is accessible via the Square API (which absorbed Weebly's customer management). Export member data using Square's Customers API (/v2/customers) and import email addresses and member details into Supabase. For email subscribers, export the CSV from Weebly admin → Marketing → Subscribers. Re-subscribe them to your new email service (Mailchimp, ConvertKit, etc.) after migration, following email permission and re-consent requirements for your region.
