Mercado Libre Connector for WooCommerce

Key Features

OAuth 2.0 authentication to the Mercado Libre API with automatic refresh-token rotation stored securely in wp_options

Two-way inventory sync that decrements WooCommerce stock on a Mercado Libre sale and updates listings on a WooCommerce order to prevent oversells

wp-admin settings screen under WooCommerce for credentials, sync mode and on-demand sync triggers

Category and attribute mapping from WooCommerce taxonomies to Mercado Libre's required category tree and item specifications

Multi-site marketplace support for MLA (Argentina), MLB (Brazil), MLM (Mexico) and other Mercado Libre sites

About this Product

The Mercado Libre Connector for WooCommerce bridges your WordPress/WooCommerce catalog with Mercado Libre's marketplace so you stop maintaining two stores by hand. ECOSIRE builds, installs and supports this plugin directly on your site — it is not an instant WordPress.org download. We scope your catalog, MercadoLibre seller account and site (HPOS, WPML, multisite) first, then deliver a working integration.

Under the hood it authenticates to the Mercado Libre API via OAuth 2.0 (with automatic refresh-token rotation stored in wp_options) and talks to your store through the WooCommerce REST API and native WordPress hooks. When you save a product, a woocommerce_update_product action queues a publish/update job; WP-Cron (or a real server cron we configure) drains the queue so stock, price and status flow to your active listings without blocking checkout.

Inventory and price changes are two-way aware: a sale on Mercado Libre decrements WooCommerce stock and a WooCommerce order decrements the matching listing, preventing oversells. Incoming Mercado Libre orders are imported as native WooCommerce orders (HPOS / custom order tables compatible) with buyer, shipping and Mercado Envíos data mapped to order meta, so your existing fulfilment, invoicing and reporting tools just work.

A wp-admin settings screen under WooCommerce lets you map WooCommerce categories and attributes to Mercado Libre's required category tree and item specifications, set listing type and pricing rules, and run on-demand syncs. Multi-site marketplace support covers MLA (Argentina), MLB (Brazil), MLM (Mexico) and other Mercado Libre sites from one install. Everything is logged via WooCommerce's logger for auditability, and we hand over documentation so your team can operate it confidently.

Who this is for

Multi-marketplace LATAM seller

A retailer selling on Mercado Libre in two or more countries (e.g. MLA and MLM) who runs WooCommerce as the master catalog and needs stock and prices to stay aligned automatically across sites.

Operations manager fighting oversells

Someone who has been manually copying stock numbers between WooCommerce and Mercado Libre, suffering cancellations and reputation hits, and wants order import plus two-way inventory sync to end the double-entry.

Agency or in-house WordPress developer

A technical owner who wants a maintainable plugin built on WooCommerce REST API and WordPress hooks, HPOS-compatible, with filters they can extend, rather than a brittle CSV import or a black-box SaaS.

Frequently Asked Questions about Mercado Libre Connector for WooCommerce

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

No. This is a build-to-order plugin. ECOSIRE builds, installs and configures it directly on your WordPress/WooCommerce site, connects your Mercado Libre seller account via OAuth, and maps your catalog. You receive a working integration, not a generic ZIP to wire up yourself.

How long does delivery take?

Typical delivery is about 1 to 3 weeks after we receive your Mercado Libre API credentials, site access and catalog details. Timing depends on catalog size, the number of Mercado Libre sites (MLA/MLB/MLM), category-mapping complexity and whether your store uses HPOS, WPML or multisite. We confirm a concrete lead time during scoping before you commit.

What ongoing support and updates are included?

The one-time build includes a defined support and update window during which we fix issues and adjust for Mercado Libre API changes. Mercado Libre periodically updates its API, category tree and required attributes, so we offer an optional ongoing maintenance arrangement after the initial window to keep the connector current. We scope this with you so there are no surprises.

Does it prevent overselling across WooCommerce and Mercado Libre?

Yes. Inventory sync is two-way aware: a sale on Mercado Libre decrements WooCommerce stock and a WooCommerce order updates the matching Mercado Libre listing. A queued, cron-driven sync keeps both sides reconciled so you avoid the cancellations that hurt your seller reputation. Sync frequency is configured to fit your volume.

Will it work with my existing theme, plugins and HPOS setup?

Yes. Imported Mercado Libre orders are created as native WooCommerce orders and are compatible with HPOS / custom order tables, so your fulfilment, invoicing and reporting tools work unchanged. We verify compatibility with your theme, WPML or multisite configuration and key plugins during the build, and the connector exposes WordPress hooks and filters for further customization.
