Walmart Marketplace Connector

Key Features

Walmart Marketplace REST API client wrapped behind Magento service contracts (PHP interfaces) with signed authentication, retry/backoff, and full request/response logging

Product upload and feed mapping that translates your Magento attribute set and attribute values into Walmart item spec fields per category

Inventory sync that respects Magento MSI (Multi-Source Inventory) sources, stocks, and salable quantity, pushing updates to Walmart on cron and on stock events

Price sync (base price, sale price, and optional repricing rules) with per-SKU push and bulk reconciliation

Order import that pulls Walmart orders into native Magento sales orders, plus acknowledgment back to Walmart and shipment/tracking updates

Walmart category taxonomy mapping UI that links Magento categories/attribute sets to Walmart product categories and required attributes

Bulk product management from a dedicated admin grid: select, validate, queue, and submit hundreds of SKUs with per-row status

Feed lifecycle tracking by Walmart feed ID with per-SKU success/error reasons surfaced in the admin

Cron-driven scheduled jobs for inventory, price, and order polling, with configurable intervals and concurrency limits

Admin configuration section under Stores > Configuration, ACL-gated so only authorized roles can edit Walmart credentials and sync rules

Observers and plugins on catalog save, stock, and order events for near-real-time sync without blocking the storefront

Detailed sync logging and an audit trail (success, partial, error) per entity, with retry of failed submissions

Multi-store / multi-website aware mapping so different store views can publish to the correct Walmart account or catalog scope

Sandbox/production environment toggle for safe pilot testing before going live

About this Product

The Walmart Marketplace Connector is a Magento 2 / Adobe Commerce extension that ECOSIRE builds to order, installs on your store, and supports — it is not an instant Adobe Commerce Marketplace download. We engineer it around your attribute set, catalog structure, and Walmart category requirements so feed mapping actually matches your data instead of forcing you to re-key thousands of SKUs.

Delivered as a proper module under app/code/Ecosire/WalmartConnector, it follows Magento conventions end to end: service contracts (PHP interfaces) for the Walmart API client, di.xml wiring, plugins/interceptors and observers for catalog and order events, a typed admin configuration section gated by ACL, and cron jobs for scheduled inventory, price, and order polling. The Walmart Marketplace REST API (Items, Inventory, Prices, Orders, and Feeds endpoints) is wrapped behind a versioned client with signed authentication, retry/backoff, and full request/response logging.

Core capability covers product upload and feed mapping (Magento attributes to Walmart spec categories), inventory and price sync respecting your MSI source/stock setup, order import with acknowledgment back to Walmart, category taxonomy mapping, and bulk product management from the admin grid. Feed submissions are tracked by Walmart feed ID so you see per-SKU success and error reasons.

Because it is built to order, the connector fits Adobe Commerce or Magento Open Source, single-store or multi-store, and your existing OMS/ERP flow. ECOSIRE handles installation on staging and production, configures the Walmart credentials, validates a pilot batch of SKUs, and provides a documented warranty and optional support retainer. Honest lead times and scope are confirmed in writing before we start.

Installation on your staging and production environments by ECOSIRE engineers, including setup:upgrade and DI compilation

Walmart Marketplace API credential configuration and connection validation against your seller account

Who this is for

US multichannel seller expanding to Walmart

Already selling on their Magento storefront and other channels, they want Walmart listings populated from Magento data without manually re-keying SKUs, prices, and stock into Seller Center.

eCommerce operations manager

Owns daily catalog and order accuracy. Needs inventory and price to stay in sync across Magento and Walmart automatically, and Walmart orders to land in Magento for fulfillment alongside everything else.

Magento agency or in-house developer

Wants a properly engineered connector — service contracts, di.xml, cron, ACL, logging — that fits the existing module stack and ERP/OMS integration rather than a black-box extension they cannot extend.

Frequently Asked Questions about Walmart Marketplace Connector

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. ECOSIRE engineers it for your specific Magento version, attribute set, and Walmart catalog requirements, then installs and configures it on your environments. You are buying a custom-built, installed, and supported connector — not a self-service Marketplace download.

What is the delivery lead time?

After we confirm scope and receive your Walmart Marketplace API credentials and a catalog sample, a typical build-and-install runs about 2 to 4 weeks depending on catalog complexity, number of Walmart categories, and any ERP/OMS integration. We confirm an exact timeline in writing before starting and keep you updated through staging validation.

How do you handle ongoing support and updates?

Every build includes a documented warranty period for defect fixes. Beyond that, an optional support retainer covers Walmart API version changes, Magento/Adobe Commerce upgrades, new attribute or category mappings, and feature enhancements. You own the source code, so your own team can also maintain it.

Does it work with Adobe Commerce and Magento Open Source, and with MSI?

Yes. The connector is built for your edition, whether Adobe Commerce or Magento Open Source, and is aware of Magento Multi-Source Inventory (MSI). Inventory sync reads your configured sources, stocks, and salable quantity so Walmart stock reflects the correct fulfillment picture.

Can it import Walmart orders into Magento and acknowledge them back?

Yes. Walmart orders are pulled on a cron schedule into native Magento sales orders, acknowledged back to Walmart so they are not flagged as unprocessed, and shipment/tracking updates are pushed back to Walmart when you ship. This keeps Walmart fulfillment inside your normal Magento order workflow.
