Walmart Marketplace Integration for Magento 2

Key Features

Custom module under app/code/Ecosire/WalmartMarketplace with registration.php, module.xml and proper sequence on Catalog, CatalogInventory/MSI and Sales

Walmart Marketplace REST API client (Items, Inventory, Prices, Orders, Fulfillment) with WM_SEC token auth, refresh and rate-limit-aware retry, wired through di.xml

Bulk product upload with an admin attribute-to-Walmart-spec mapping grid and a compliant feed builder that tracks per-SKU acceptance and error feedback

Near-real-time inventory and price sync via observers on stock and price events plus cron-scheduled reconciliation jobs

Bulk operations queued through Magento_AsynchronousOperations so large catalog/feed pushes don't block the admin

Walmart order import that creates native Magento sales orders, sends acknowledgements, and pushes shipments and tracking back to Walmart

WFS (Walmart Fulfillment Services) support — Walmart-fulfilled orders are detected, flagged and excluded from your own shipping workflow

Repricing and promotional pricing rules evaluated server-side before each price push to Walmart

Service-contract interfaces and DI-injected dependencies for clean, unit-testable logic with no static coupling

System configuration section with environment toggle (sandbox/production), credential storage and store-view-scoped settings

Admin ACL resources (Ecosire_WalmartMarketplace::config) and dedicated Monolog log channel for auditable, scoped access

Compatible with Magento Open Source and Adobe Commerce; MSI-aware so multi-source inventory maps correctly to Walmart stock

About this Product

This is a build-to-order Magento 2 extension, not an instant Adobe Commerce Marketplace download. After purchase, ECOSIRE builds the connector against your Magento version, installs it on your environment, and supports it going forward. It ships as a proper module under app/code/Ecosire/WalmartMarketplace, registered through registration.php and a module.xml with explicit sequence on Magento_Catalog, Magento_CatalogInventory (or MSI Magento_Inventory) and Magento_Sales.

The extension talks to the Walmart Marketplace REST API (Items, Inventory, Prices, Orders and Fulfillment endpoints) using OAuth-style WM_SEC.ACCESS_TOKEN auth with token refresh, signed correlation headers and rate-limit-aware retry. All outbound calls run through a dedicated Guzzle-based client wired via di.xml against a service-contract interface, so logic stays testable and swappable.

Catalog is mapped to Walmart's category spec via an admin grid: Magento attributes are bound to Walmart required/recommended fields, with a feed builder that produces compliant item payloads and tracks per-SKU acceptance/error state. Inventory and price sync run on cron (configurable, queue-backed via Magento_AsynchronousOperations for bulk) and react in near-real-time to stock and price changes through observers on sales_order_place_after, cataloginventory_stock_item_save_after and catalog price events. Order import pulls Walmart orders, creates native Magento orders, and pushes acknowledgements, shipments and tracking back (including WFS fulfillment routing so Walmart-fulfilled orders are flagged and not double-shipped). Repricing and promo rules are evaluated server-side before each price push.

Everything respects admin ACL (Ecosire_WalmartMarketplace::config), logs to a dedicated channel, and works on both Magento Open Source and Adobe Commerce. You get the source — no encrypted blobs, no license phone-home.

What you get

Full extension source installed under app/code/Ecosire/WalmartMarketplace on your environment (no encrypted code, no license callbacks)

Installation and configuration on your Magento 2 / Adobe Commerce instance, including credential setup and a sandbox connection test

Attribute-to-Walmart-spec field mapping configured for your catalog's product types and categories

Cron jobs and queue consumers configured for inventory, price and order sync

Technical documentation covering configuration, the sync model, mapping rules and troubleshooting

Post-launch support window with bug fixes and Walmart API compatibility updates per the agreed terms

Who this is for

US Magento merchant expanding to Walmart

A US-focused Adobe Commerce or Magento Open Source seller approved on Walmart Marketplace who wants their existing catalog, stock and pricing to flow to Walmart without re-keying data or running a second admin.

Operations lead drowning in manual order entry

An ecommerce ops manager copying Walmart orders into Magento by hand and updating tracking in two places, who needs orders, shipments and WFS fulfillment reconciled automatically inside native Magento.

Magento agency or in-house dev team

A technical team that wants real, source-available module code following Magento conventions (DI, service contracts, observers, ACL) they can read, extend and maintain, rather than a black-box marketplace plugin.

Frequently Asked Questions about Walmart Marketplace Integration for Magento 2

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. After purchase, ECOSIRE builds the connector against your specific Magento version and catalog, then installs it on your environment. There is no Marketplace download link — you receive the working, installed module and its full source.

How long until it's live on my store?

Typical delivery is about 2 to 4 weeks from kickoff, depending on your catalog complexity, product types, whether you use MSI, and how much custom attribute mapping Walmart's category spec requires. We confirm a firm timeline after a short scoping call and account access review.

What do you need from me to get started?

Your Walmart Marketplace API credentials (Client ID/Secret for the seller account), admin and SSH/deploy access to a staging environment, your Magento version and edition, and a representative export of the catalog you want listed. We start in Walmart's sandbox before touching production.

Does it support ongoing updates and support after launch?

Yes. The build includes a post-launch support window covering bug fixes and updates for Walmart API changes. Because Walmart periodically revises its item spec and endpoints, we offer continued maintenance so the connector keeps passing item validation and order sync — terms are agreed up front.

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

Yes. The module targets Magento 2 conventions common to both editions and is Multi-Source Inventory aware, so multi-warehouse stock can be aggregated or mapped per Walmart's single stock-per-item model. We confirm exact version compatibility during scoping.

Will I get the source code, or is it locked?

You get the full, readable source installed under app/code — no encrypted files and no license phone-home. Your team or any Magento developer can audit, extend or maintain it after the engagement.
