Selling on both Shopify and Mercado Libre means two product catalogs, two stock counts and two order inboxes that drift apart by the hour. Oversells, stale prices and missed orders are the predictable result. The Mercado Libre Marketplace Connector is a Shopify app that ECOSIRE builds, installs and supports for your specific store — it is not an instant App Store download, and we do not pretend otherwise.

The connector authenticates to Mercado Libre via OAuth 2.0 and to your store through the Shopify Admin GraphQL API. It maps each Shopify product and variant to its corresponding Mercado Libre listing (MLA/MLB/MLM/MLC and other site IDs), then keeps them aligned in near real time. When an order is paid on Mercado Libre, it is imported as a native Shopify order; when you fulfill and add tracking in Shopify, fulfillment status flows back. Inventory updates are debounced and idempotent, so a sale on either channel decrements the right multi-location stock without double-counting.

Because every catalog is different, we tailor the field mapping, category and attribute logic, and price/stock rules to your products during the build. We use Shopify webhooks (products/update, orders/create, inventory_levels/update) plus a reconciliation job so transient API failures self-heal rather than silently desync. Listing data lives in metafields for auditability.

Delivery is honest and scoped: after purchase we confirm requirements, build, test against your real catalog, and install it on your store. You get a working integration plus documentation — not a black box. Pricing covers a standard build; complex catalogs or extra Mercado Libre sites are quoted up front.
