Mercado Libre Integration for WooCommerce

Key Features

Two-way sync of products, stock levels and prices between WooCommerce and Mercado Libre via the official Items API and WooCommerce REST API

Automatic listing publication, update and pause driven by WooCommerce product status and stock, using woocommerce_update_product and stock-change hooks

Order import from Mercado Libre into native WooCommerce orders, fully compatible with HPOS / custom order tables

Per-regional-site support for MLM (Mexico), MLA (Argentina), MLB (Brazil), MLC (Chile), MCO (Colombia) and other Mercado Libre sites

Mercado Libre category prediction plus required and variation attribute mapping configured per site in wp-admin

OAuth 2.0 app registration and automatic access-token refresh handled by a scheduled WP-Cron job (server-cron option available)

Near-real-time updates via Mercado Libre Notifications (webhooks) for orders, questions and item status changes

Variation grid mapping so WooCommerce variable products become correct Mercado Libre variations (size, color, etc.)

Configurable price rules per marketplace (markup, currency, rounding) so marketplace pricing differs from your storefront

Conflict-safe stock reconciliation with batch jobs, retry queue and idempotency to avoid overselling across channels

WPML / WordPress multisite aware so localized catalogs map to the correct Mercado Libre regional account

Detailed sync log in wp-admin (per-item status, last-synced timestamp, API error capture) for auditing and troubleshooting

About this Product

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.

What you get

A custom WooCommerce plugin built for your store and installed on your WordPress site by ECOSIRE

Mercado Libre application registration and OAuth 2.0 connection completed and tested for each regional site you sell on

Initial catalog mapping: WooCommerce products mapped to Mercado Libre categories, attributes and variation grids

Configured WP-Cron (or server cron) sync schedule plus webhook endpoints for order and item notifications

HPOS-compatible order import wired into your existing WooCommerce fulfillment and reporting workflow

Admin handover documentation and a walkthrough covering the settings screen, sync log and re-sync controls

Who this is for

LATAM cross-border WooCommerce seller

Runs a WooCommerce store and sells into multiple Mercado Libre countries. Needs one catalog to drive MLM, MLA, MLB, MLC and MCO listings without re-keying products per site.

Operations / fulfillment manager

Wants Mercado Libre orders flowing straight into WooCommerce as native orders so packing, invoicing and reporting stay in one system and stock never oversells across channels.

Agency or in-house developer

Manages a client's WooCommerce site and prefers a supported, build-to-order integration over maintaining a fragile custom Mercado Libre API connector and token-refresh logic in-house.

Frequently Asked Questions about Mercado Libre Integration for WooCommerce

How long does delivery take, since this isn't an instant download?

This is a build-to-order plugin. After purchase, ECOSIRE scopes your catalog and target regional sites, then builds, installs and configures the integration on your WordPress site. Typical delivery is around 2 to 4 weeks depending on how many Mercado Libre sites you sell on and the complexity of your category and attribute mapping. We confirm a firm timeline with you before starting and keep you updated through build and go-live.

What ongoing support and updates are included?

Because the plugin runs on your own WordPress site, you own it outright. ECOSIRE provides post-launch support to resolve sync issues, and we update the integration when Mercado Libre changes its Items, Orders or Notifications API, or when WooCommerce/WordPress releases (including HPOS changes) affect it. Support scope and duration are agreed in your engagement; extended maintenance is available.

Which Mercado Libre countries and sites are supported?

The integration is built around Mercado Libre's regional sites — Mexico (MLM), Argentina (MLA), Brazil (MLB), Chile (MLC) and Colombia (MCO) are commonly configured, and other Mercado Libre sites can be added. Each site is connected with its own OAuth application and its own category/attribute mapping, because required attributes differ between sites for the same SKU.

Will Mercado Libre orders work with HPOS and my existing fulfillment flow?

Yes. Imported Mercado Libre orders are created as native WooCommerce orders and are fully compatible with High-Performance Order Storage (custom order tables). They appear alongside your storefront orders, so your existing fulfillment, invoicing, shipping and reporting workflows handle them without changes.

Do I need my own Mercado Libre developer account, and how does authentication stay valid?

You need a Mercado Libre seller account; ECOSIRE registers the developer application and completes the OAuth 2.0 connection during setup. Access tokens are refreshed automatically by a scheduled WP-Cron job (or a real server cron, which we recommend for reliability), so the connection stays live without manual re-authentication.
