LystoSync for Etsy

LystoSync is a WooCommerce Etsy integration that runs inside your WordPress admin. Publish products as Etsy listings, keep prices and stock in sync, and deactivate listings when items sell out. Your listing data stays in your own WordPress database.

Core features (free):

• Publish WooCommerce products as Etsy listings: physical, digital, or both
• Variations: map WooCommerce attributes to up to three Etsy variation properties
• Listing images, variation images, digital files, and up to two videos per listing
• Personalization questions and per-language translations
• Listing profiles: reusable settings with Etsy category (taxonomy), shipping profile, processing profile, and return policy
• Shop page: manage sections, shipping profiles, processing profiles, and return policies without leaving WordPress
• Per-product shipping weight and dimensions sent to Etsy
• Deactivate, reactivate, and renew listings at any time, with Etsy’s listing fee confirmed first
• Bulk “Sync on Etsy” from the WooCommerce Products list, with progress and per-product results
• Auto-sync on product save: changes push to Etsy when you update a WooCommerce product
• Stock control: deactivate the listing when WooCommerce stock runs out
• Sales sync: automatically reduce WooCommerce stock when an item sells on Etsy, and restore it if the sale is canceled
• Background sync: queued listing updates pushed on a schedule
• Archive listings that ended more than 90 days ago, checked daily
• OAuth shop connection

Pro features (LystoSync Pro):

• Import existing Etsy listings into WooCommerce
• Orders admin page: view, search, and manage imported Etsy orders
• Automated order import on a schedule
• Mark orders as shipped on Etsy with carrier and tracking number when a WooCommerce order completes
• LystoSense: suggested titles, tags, materials, and category attributes, reviewed before anything is saved
• Faster sync intervals (5 and 15 minutes; free offers 30 minutes, hourly, or manual)
• In-dashboard Pro updates with license key activation

How it works:

LystoSync handles Etsy OAuth tokens server-side, so you never touch API credentials. All you need is an Etsy shop: the free plugin needs no API keys and no LystoSync account.

External Services

This plugin transmits data to two external services:

LystoSync (etsy-api.lystosync.com)

All Etsy API requests go through etsy-api.lystosync.com. When you connect an Etsy shop, your site URL (and, with Pro, your license key) is sent to authenticate. Subsequent requests include product data, pricing, inventory levels, order details, and shipment information, depending on which features you use. No data is sent until you connect an Etsy shop.

Separately, the plugin can check for service notices (Etsy API outages, critical fixes, and Etsy changes that need action on your shop). This is optional and off by default, and you can turn it on or off at any time under LystoSync, Settings, General, Notifications. While it is off, or before you connect an Etsy shop, no request is made. While it is on, the check sends your plugin, WordPress, WooCommerce and PHP versions, and your site language, using the same authentication as the plugin’s Etsy requests (your site URL and, with Pro, your license key). It sends no email, Etsy shop, or customer or order data.

Etsy

Product listings, pricing, inventory, and shipment data are submitted to Etsy via the LystoSync middleware. Etsy’s own privacy policy and terms of use govern how Etsy handles that data.

Source Code

The human-readable source files for all compiled assets ship with the plugin, in
resources/js/ and resources/css/, alongside the build script (build.js) and
the build dependencies (package.json). Every generated file in dist/ also
carries a header comment naming the source file it was built from.

Build tools required: Node.js, npm

To regenerate the compiled files in dist/:

1. Run npm install to install dependencies (esbuild, PostCSS, Autoprefixer).
2. Run npm run build (or node build.js) to compile and minify all assets.

The build uses esbuild for JavaScript bundling and minification, and PostCSS with Autoprefixer for CSS.

Compiled file => source file:

• dist/admin.js => resources/js/app.js
• dist/product-metabox.js => resources/js/product-metabox.js
• dist/connect.js => resources/js/connect.js
• dist/products-bulk-list.js => resources/js/products-bulk-list.js
• dist/setup.js => resources/js/setup.js
• dist/admin.css => resources/css/design-system.css + resources/css/admin.css
• dist/product-metabox.css => resources/css/product-metabox.css

Each JavaScript entry point also pulls in the shared module resources/js/lib/api.js,
which is bundled into the output rather than shipped as a separate file.

Bundled fonts. The admin interface uses two self-hosted webfonts, copied from
resources/fonts/ to dist/fonts/ by the build. Nothing is loaded from a font
CDN or any other third-party host.
