The Mercado Libre Connector is a build-to-order Shopify app that links your Shopify catalog with Mercado Libre across Latin American marketplaces — Mexico (MLM), Argentina (MLA), Brazil (MLB), Chile (MLC) and more. It is not an instant App Store download: ECOSIRE builds, installs and configures it on your store, then supports it.

Under the hood it authenticates to Mercado Libre via OAuth 2.0 and to your store through the Shopify Admin GraphQL API, registering webhooks for products/update, inventory_levels/update and orders/create so changes flow without manual exports. Shopify multi-location inventory is mapped to your Mercado Libre stock so available_quantity stays accurate, and a configurable price sync applies per-site currency, rounding and optional margin rules.

We handle the parts that off-the-shelf apps gloss over: title and attribute (ficha técnica) mapping, category-required attributes per site, variation/variant alignment, and listing creation or matching by SKU or existing MLB item ID. Incoming Mercado Libre orders import as Shopify orders, and fulfillment / tracking writes back to Mercado Libre so the buyer sees shipping status. Conflicts, rate limits and partial failures are logged with retry, and field mappings live in Shopify metafields plus an admin settings panel so you stay in control.

Because every catalog and marketplace mix is different, the build is scoped to your SKUs, sites and theme during a short discovery call. You get a working, installed integration — plus the source and documentation — rather than a black box. This is honest custom work: a defined scope, a real delivery lead time, and a human team behind it.
