How We Integrate Walmart Marketplace With Your Store
Selling on Walmart Marketplace in the US means working through Walmart's official Marketplace API — a real REST platform covering items, orders, inventory, price and fulfilment. AppsyOne builds a custom bridge between your own store and that API so approved orders drop straight into your systems, stock and pricing stay accurate, and you stop re-keying between Seller Center and a spreadsheet. It plugs directly into a custom appsy.one ecommerce build rather than a rented dashboard you never truly control.
This matters most for overseas and Indian sellers expanding into the US. Walmart Marketplace has its own catalogue rules, GTIN and category requirements, and US sales-tax obligations that generic connectors handle badly. We map your SKUs to Walmart items the way your business actually works, push inventory and price updates through the API, and pull orders and fulfilment status back on a schedule you set — with Walmart Fulfillment Services (WFS) or your own 3PL wired in where you need it.
Getting live on Walmart is a gated process: items clear GTIN and UPC validation plus item-setup approval before a single listing turns searchable. Once you're through, we run the whole pipeline as a build priced in INR — a flat setup fee, then a flat monthly — never a percentage of your US sales creamed off by us. Walmart Fulfillment Services or your own 3PL feeds the same stock count, and sales-tax nexus is calculated through Avalara or TaxJar, so your US catalogue, pricing and books stay reconciled from one place.

When a plug-and-play tool is the smart call — and when a custom build you own pays off.

We build the complete application — integrations included
Most clients need more than a connector. We build the full product — your storefront, seller portal, admin dashboard, mobile app or internal ERP — and wire the marketplace integrations into it as part of the same build. One team, one codebase, one point of accountability.
- Custom web & mobile applications
- Seller / vendor portals & dashboards
- ERP, CRM, Tally & accounting bridges
- Warehouse, inventory & order management
- Payment, logistics & shipping APIs
- Workflow automation and AI features
Full custom builds are scoped and quoted to your requirement — not packaged into the plans above.
