Mercado Libre Connector for Business Central

Key Features

Inbound order sync from the Mercado Libre REST API into native BC Sales Orders, with buyer, billing/tax data and order-item mapping to BC Items and variations

Mercado Envíos fulfillment sync — shipment status, tracking, labels-printed and delivery events written back onto the linked BC sales document via event subscribers

Listing stock push-back: BC available inventory changes propagate to Mercado Libre quantity (loop-guarded so marketplace-originated sales don't re-trigger a push)

Price update sync from BC item/price changes to the matching Mercado Libre listing, with per-site and per-listing override controls

Question and post-sale message awareness — unanswered buyer questions surfaced in a BC list page so support SLAs are not missed

Settlement and fee reconciliation: Mercado Libre commission, Mercado Envíos shipping cost and financing fees parsed and posted as G/L charge lines for clean margin reporting

Returns and claims handling mapped to BC Return Orders / Credit Memos with reason-code mapping

OAuth2 authentication with encrypted token storage and automatic refresh-token rotation in a dedicated isolated setup table

Job Queue–driven polling with configurable intervals, structured error log, and retry/skip handling per record

Item and warehouse mapping tables (BC Item ↔ ML item ID + variation ID ↔ location/warehouse) for accurate multi-warehouse stock

Multi-site support (MLA, MLB, MLM, MLC, MCO and others) with per-account credentials and currency handling

Dedicated permission sets restricting setup, sync operation and credential visibility by role

Optional OData/Dataverse exposure for Power BI settlement dashboards and Power Automate notifications

Idempotent processing with external-ID de-duplication so re-polls never create duplicate orders or postings

About this Product

Mercado Libre Connector for Business Central is a custom-built integration that wires the Mercado Libre marketplace and Mercado Envíos logistics into your existing Dynamics 365 Business Central environment, so order capture, inventory, pricing and settlement stop being a daily spreadsheet chore.

This is a build-to-order engagement, not an instant AppSource download. ECOSIRE develops the connector as an AL language extension, deploys it as a per-tenant extension to your Business Central Online (or on-prem) environment, and supports it afterward. We scope your Mercado Libre site(s) — MLA (Argentina), MLB (Brazil), MLM (Mexico), MLC (Chile), MCO (Colombia) and others — your seller account topology, and your BC localization before a single line ships.

Technically, the extension authenticates to the Mercado Libre REST API using OAuth2 (app ID, secret and refresh-token rotation handled in an isolated setup table with token encryption). Inbound orders, shipments and questions are polled and processed through the Job Queue, then projected onto standard BC documents — Sales Orders, Posted Sales Invoices and Item Ledger Entries — via table and page extensions plus event subscribers on posting routines. Listing stock and price are pushed back to Mercado Libre when BC inventory or price changes, guarded against feedback loops.

You get dedicated setup pages, a Mercado Libre Order worksheet, mapping tables (item ↔ MLB item ID, variation, warehouse), structured error logging, and permission sets so staff see only what they should. The connector can also surface to Power Platform via the Business Central OData/Dataverse layer if you want Power BI settlement dashboards or Power Automate alerts.

Honest expectation: a typical single-site build is delivered in roughly 3–5 weeks; multi-site or heavy customization runs longer. The $499 covers the standard scoped build and installation.

What you get

A per-tenant Business Central AL extension (.app) built to your scoped Mercado Libre site(s) and BC localization, installed on your environment

Source AL project (table/page extensions, codeunits, event subscribers, permission sets) handed over to you

Configured setup pages, mapping tables and Job Queue entries on your tenant, ready to run

OAuth2 connection to your Mercado Libre seller app, with encrypted credential storage configured

UAT walkthrough in a sandbox: order, shipment, stock push, settlement and return test cases verified before go-live

Admin runbook documenting setup fields, mappings, error-log handling and re-sync procedure

Post-go-live support window and an agreed plan for ongoing updates and API-change maintenance

Who this is for

LATAM Marketplace Operations Lead

Runs daily Mercado Libre selling across one or more sites and is tired of re-keying orders and tracking numbers into Business Central by hand. Wants orders, shipments and stock to flow automatically with an audit trail.

Business Central Finance Controller

Needs Mercado Libre commissions, Mercado Envíos shipping and financing fees posted as real G/L charges so marketplace margin and settlement reconciliation are accurate, not estimated in spreadsheets.

IT / ERP Manager

Owns the BC environment and insists any integration be a clean per-tenant AL extension with permission sets, encrypted credentials, Job Queue scheduling and a supplier who maintains it against API changes — not a fragile in-house script.

Frequently Asked Questions about Mercado Libre Connector for Business Central

Is this an instant AppSource download?

No. This is a build-to-order engagement. ECOSIRE develops the connector as an AL extension scoped to your Mercado Libre site(s) and your Business Central localization, then installs it on your tenant as a per-tenant extension and supports it. There is no instant marketplace download.

How long until it's live, and what does the $499 cover?

A typical single-site build is delivered in roughly 3–5 weeks from when we have your Mercado Libre app credentials and a sandbox. Multi-site or heavily customized scopes take longer. The $499 covers the standard scoped build, configuration on your tenant and a UAT walkthrough; we confirm exact scope and timeline before starting.

What happens to ongoing support and updates after go-live?

You get a post-go-live support window, and we offer ongoing maintenance to keep the connector working when the Mercado Libre REST API or your Business Central version changes (BC ships major updates twice a year). Because you also receive the source AL project, you are never locked in if you choose to maintain it yourself.

Will it create duplicate orders or fight my inventory?

No. Inbound processing is idempotent and de-duplicates on the Mercado Libre order/external ID, so re-polling never double-posts. Stock push-back is loop-guarded so a sale that originates on Mercado Libre does not re-trigger a redundant quantity push back to the listing.

Which Mercado Libre sites and Business Central deployments are supported?

We support the major Mercado Libre sites — MLA (Argentina), MLB (Brazil), MLM (Mexico), MLC (Chile), MCO (Colombia) and others — each with its own credentials and currency. The extension targets Business Central Online (SaaS) and can be adapted for supported on-prem deployments; we confirm your exact version during scoping.

Does it integrate with Power BI or Power Automate?

Optionally, yes. The connector's data can be exposed through Business Central's OData/Dataverse layer so you can build Power BI settlement and margin dashboards or trigger Power Automate alerts (for example, on an unanswered buyer question or a failed sync). This is included in scope when you request it.
