About this Product

Mercado Libre Connector for WooCommerce keeps your WooCommerce catalog and your Mercado Libre seller account in lockstep, so you stop managing two stores by hand. It publishes and relists your WooCommerce products to Mercado Libre, maps WooCommerce variations to ML variations and attributes, and runs bidirectional stock and price synchronization so a sale on either channel updates the other.

This is a build-to-order plugin, not an instant download. ECOSIRE builds it against the live Mercado Libre API (OAuth 2.0 app, token refresh, per-country site IDs), installs it on your WordPress site, and configures it for your catalog, listing types and shipping setup. There is no marketplace ZIP to grab and self-install — we deliver a working integration on your environment.

Under the hood it registers a dedicated wp-admin settings screen, stores the ML↔Woo mapping in custom tables and product meta, and uses scheduled jobs (real cron or WP-Cron) to poll for orders and reconcile inventory. Orders flow in as native WooCommerce orders — HPOS / custom order tables compatible — carrying Mercado Envíos shipping selection and tracking. Inventory and price changes are driven through WooCommerce's own hooks (woocommerce_product_set_stock, woocommerce_update_product) so your existing stock logic stays the source of truth.

It supports multiple Mercado Libre country sites (MLA Argentina, MLB Brazil, MLM Mexico, MLC Chile and others), Clásica/Premium listing-type selection, and category attribute mapping per site. Because we build it for you, edge cases specific to your business — bundle SKUs, currency, tax fields, fulfilment rules — are handled during the build rather than left as "not supported."

Every install includes a defined warranty window plus optional ongoing maintenance to track Mercado Libre API changes.

Who this is for

LatAm WooCommerce store owner selling on Mercado Libre

Runs a WooCommerce store and also lists on Mercado Libre in one or more countries, and is tired of manually editing stock and prices in two places. Needs reliable real-time multichannel sync so overselling and stale listings stop.

Cross-border seller across multiple ML sites

Sells the same catalog into Argentina, Brazil, Mexico or Chile and needs one WordPress install to drive several Mercado Libre country sites with per-site categories, attributes and listing types.

Operations / fulfilment manager

Owns order processing and shipping. Wants Mercado Libre orders to land as native WooCommerce orders with Mercado Envíos shipping and tracking, so the existing fulfilment, invoicing and reporting workflow keeps working without a second dashboard.

Frequently Asked Questions about Mercado Libre Connector for WooCommerce

Is this an instant download I can install myself from WordPress.org or WooCommerce.com?

No. This is a build-to-order plugin. ECOSIRE builds it against the live Mercado Libre API, then installs, configures and tests it directly on your WordPress site. There is no public marketplace ZIP to self-install — you receive a working integration on your own environment, not a generic download.

How long until it's delivered and live on my store?

Typical delivery is about 2 to 4 weeks from kickoff, depending on catalog size, how many Mercado Libre country sites you sell on, and the complexity of your variation and attribute mapping. After we review your store and ML account we confirm a firm lead time before starting. A staging-site build and validation happens before anything touches production.

What ongoing support and updates are included?

Every build ships with a warranty window to fix any defects in the delivered functionality. Because Mercado Libre periodically changes its API, listing rules and required attributes, we also offer an optional maintenance plan that keeps the connector compatible, applies updates, and provides ongoing support. Without a maintenance plan the plugin keeps running, but API changes on Mercado Libre's side may eventually require paid updates.

Does it work with HPOS and my existing WooCommerce extensions?

Yes. Imported Mercado Libre orders are created as native WooCommerce orders and are compatible with High-Performance Order Storage (HPOS / custom order tables), so your existing reporting, invoicing and fulfilment extensions keep working. We use WooCommerce's standard hooks and the REST API rather than bypassing core, and we validate against your active plugin stack during the build.

Can it sync several Mercado Libre countries from one WooCommerce store?

Yes. The connector supports multiple Mercado Libre country sites (MLA Argentina, MLB Brazil, MLM Mexico, MLC Chile and others) from a single WordPress install. Each site can have its own category and attribute mapping, listing-type defaults and currency handling. Mappings that are specific to your business are configured during the build.

What happens to stock when an item sells on Mercado Libre?

Inventory is bidirectional. A sale on Mercado Libre imports the order and decrements WooCommerce stock through WooCommerce's own stock hooks; a WooCommerce sale or manual stock edit pushes the new quantity back up to the matching Mercado Libre listing. You can designate which channel is the source of truth per field to control conflict handling.
