Mercado Libre Connector for WooCommerce

Key Features

Two-way product publishing: push WooCommerce products to Mercado Libre as new listings and pull listing changes back, with field-level mapping for title, description, pictures, and variations

Real-time stock sync via WooCommerce stock hooks (woocommerce_product_set_stock / woocommerce_reduce_order_stock) so a sale on either channel decrements the other within seconds

Price sync with configurable markup or rounding rules per marketplace, respecting each site's currency (ARS, BRL, MXN, COP, CLP)

Order import from Mercado Libre webhooks/notifications into native WooCommerce orders, HPOS (custom order tables) compatible

Marketplace-to-WooCommerce order status mapping (paid, shipped, delivered, cancelled) plus buyer and shipping address capture

Per-country category and attribute mapping against each Mercado Libre site's category tree and required-attribute schema (MLA, MLB, MLM, MLC, MCO)

Multi-site / multi-account support: connect several Mercado Libre seller accounts across countries from one WooCommerce store

OAuth 2.0 authentication with automatic access-token refresh, credentials stored server-side in wp_options (not exposed to the browser)

WP-Cron reconciliation job that periodically reconciles stock, price, and order state to self-heal missed webhook events

Dedicated wp-admin settings panel: account connection, listing-type defaults, markup rules, sync log, and manual re-sync buttons

Variation/SKU matching so WooCommerce variable products map to Mercado Libre item variations by attribute combination

Structured sync logging with retry/backoff on Mercado Libre API rate limits and clear error surfacing in wp-admin

About this Product

Mercado Libre Connector for WooCommerce keeps your WooCommerce catalog and your Mercado Libre listings in lockstep across every LATAM site you sell on — MLA (Argentina), MLB (Brazil), MLM (Mexico), MLC (Chile), MCO (Colombia) and the rest. No more editing the same product twice, no more overselling when a unit moves on one channel but not the other.

This is build-to-order software, not an instant download. ECOSIRE builds the plugin against the Mercado Libre Items, Orders, and Shipments REST APIs, configures the OAuth 2.0 app credentials and token refresh, and installs it directly on your WordPress site. We map your WooCommerce categories and attributes to each country's Mercado Libre category tree and required attributes during onboarding, so publishing actually validates the first time.

Under the hood it hooks into WooCommerce the right way: stock and price changes fire on woocommerce_product_set_stock and woocommerce_update_product, a WP-Cron reconciliation pass catches anything missed, and inbound orders are pulled via Mercado Libre webhooks/notifications and written as native WooCommerce orders — HPOS (High-Performance Order Storage) compatible, with marketplace order status mapped to your WooCommerce statuses.

You get a dedicated wp-admin settings screen for connecting accounts, choosing per-site listing types, setting price markup rules per marketplace, and watching a sync log. Multi-currency is respected per site (ARS, BRL, MXN, COP, CLP).

Because we build and host it on your stack, there's no per-order SaaS fee — a one-time build, then optional support. We deliver, install, smoke-test against a sandbox or low-volume live listing, and hand over documentation.

Mercado Libre OAuth 2.0 application setup and token-refresh configuration wired to your seller account(s)

Per-country category and attribute mapping configured for the marketplaces you sell on (MLA, MLB, MLM, etc.)

wp-admin settings screen for accounts, listing types, price/markup rules, and the sync log

WP-Cron reconciliation schedule configured for stock, price, and order self-healing

Who this is for

Cross-border LATAM retailer

Sells the same catalog on Mercado Libre in two or more countries (e.g. MLA and MLM) plus a WooCommerce store, and is tired of maintaining stock and prices in three places by hand.

High-SKU WooCommerce merchant

Runs hundreds or thousands of products with variations and needs reliable SKU-level stock sync so a single oversell doesn't trigger a Mercado Libre reputation penalty.

Operations lead at a growing brand

Wants marketplace orders to land as native WooCommerce orders for fulfillment, accounting, and reporting — without a per-order SaaS connector eating margin as volume scales.

Frequently Asked Questions about Mercado Libre Connector for WooCommerce

Is this an instant plugin download I can install myself?

No. This is a build-to-order plugin. ECOSIRE builds it against the Mercado Libre REST API for your specific marketplaces and store configuration, then installs it on your WordPress site and configures the OAuth connection. You are buying custom development plus installation, not a self-service marketplace download.

How long until it's live on my store? (delivery / lead time)

Typical delivery is about 2 to 4 weeks from kickoff, depending on how many Mercado Libre country sites and seller accounts you connect and how complex your category/attribute mapping is. After we confirm scope and receive API access, we build, install, smoke-test against a sandbox or a low-volume live listing, and hand over. We'll give you a firm date once we scope your catalog.

What about ongoing support and updates?

The $249 is a one-time build. We offer an optional support and maintenance plan that covers Mercado Libre API changes, WooCommerce/WordPress version compatibility (including HPOS changes), bug fixes, and adding new country sites. Because the plugin runs on your own server, there is no per-order or per-listing SaaS fee — you own the install.

Which Mercado Libre countries and currencies are supported?

Any Mercado Libre site exposed by their API — MLA (Argentina), MLB (Brazil), MLM (Mexico), MLC (Chile), MCO (Colombia), and others. Each site's category tree, required attributes, and local currency (ARS, BRL, MXN, COP, CLP) are handled per marketplace. We configure the specific countries you sell on during onboarding.

Will Mercado Libre orders show up as real WooCommerce orders?

Yes. Inbound orders are pulled via Mercado Libre notifications and written as native WooCommerce orders, compatible with HPOS (High-Performance Order Storage). Marketplace statuses are mapped to your WooCommerce order statuses, and buyer and shipping details are captured so your normal fulfillment, invoicing, and reporting flows work unchanged.

How does it avoid overselling between WooCommerce and Mercado Libre?

Stock changes fire on WooCommerce stock hooks and push to Mercado Libre in near real time, and vice versa for marketplace sales. A WP-Cron reconciliation job periodically re-checks stock, price, and order state to self-heal any event missed due to an API outage or rate limit, with retry and backoff built in.
