Mercado Libre Marketplace Connector
Edition: CS-Cart & Multi-Vendor · Latest version: 1.0.0 · Compatible with: CS-Cart & Multi-Vendor 4.17.2 – 4.21.x, PHP 7.4 – 8.3 · Changelog: view
Sells your CS-Cart and Multi-Vendor catalog on Mercado Libre (Mexico, Brazil, Argentina, Chile, Colombia, Uruguay, Peru): category and attribute mapping, the category predictor, price rules, item creation with GTIN handling, stock and price updates, order import by notification and polling, Mercado Envios labels and own-carrier tracking, all through your own Mercado Libre application.
What it does
Section titled “What it does”- Maps CS-Cart categories to Mercado Libre categories (the category predictor suggests one from the product title) and product features to Mercado Libre attributes, with a price markup per category or product, price endings and a stock buffer.
- Creates items on Mercado Libre from mapped products: category, price in the currency of the site, stock, listing type, pictures by URL, attributes with the value ids of closed lists, the SKU as SELLER_SKU, the barcode as GTIN when it is a valid one (otherwise the empty-GTIN reason that the category asks for), a plain text description, shipping mode and an optional seller warranty. Every product shows its own reason when Mercado Libre refuses it.
- Updates stock and price with one call per item and reports what Mercado Libre refused, for example a price that is under automation or a campaign.
- Imports paid orders into CS-Cart without duplicates (buyer, delivery address, prices as sold), follows shipment status changes, and cancelled orders.
- Receives Mercado Libre notifications (topics orders_v2, items and shipments), answers at once and processes them from the queue; polling is the fallback, so a lost notification only delays an order.
- Mercado Envios 2: downloads the shipment label (PDF or ZPL) from the Orders page. Own carrier (custom shipping): reports the tracking number and the status shipped.
- You create your own application in the Mercado Libre developer center and authorize it once; the client secret and the tokens are stored encrypted, the single-use refresh token is replaced at every refresh.
- A job queue with automatic retries (5 minutes, 15 minutes, 1 hour, 3 hours, 12 hours), a log with filters and CSV export.
- Multi-Vendor: marketplace owner mode (one Mercado Libre account for the whole marketplace) or one Mercado Libre account per vendor in the vendor panel.
