Mercado Libre Integration for WooCommerce is a build-to-order plugin that turns your WooCommerce store into the single source of truth for selling across Mercado Libre's LATAM marketplaces — MercadoLibre Mexico (MLM), Argentina (MLA), Brazil (MLB), Chile (MLC) and Colombia (MCO). Instead of manually re-keying listings in each regional site, you manage products in wp-admin and let the integration publish, update and reconcile them through Mercado Libre's official OAuth 2.0 Items, Orders and Notifications APIs.

This is not an instant download. ECOSIRE builds, installs and configures the plugin on your WordPress site, maps it to your live catalog, and supports it after go-live. We register your Mercado Libre application, complete the OAuth flow, and wire the sync engine to your actual category tree and attribute requirements — work that off-the-shelf plugins leave to you.

Under the hood it uses the WooCommerce REST API and native WordPress hooks (woocommerce_update_product, woocommerce_reduce_order_stock) so stock and price changes propagate without polling everything. A dedicated WP-Cron schedule handles batch reconciliation and token refresh, with an option to run via a real server cron for reliability. Incoming Mercado Libre orders are imported as native WooCommerce orders — fully HPOS / custom order tables compatible — so your existing fulfillment, invoicing and reporting flows just work.

Category and attribute mapping (predicted category, required attributes, variation grids) is configured per regional site, because the same SKU needs different metadata in MLB vs MLM. Listings publish, update and pause automatically based on WooCommerce stock and status. WPML / multisite setups are supported so localized catalogs map to the correct Mercado Libre site. Everything is logged, retryable, and owned by you on your own infrastructure.
