Productsup named an approved Walmart Marketplace solution provider, automating listings, pricing, and orders in one platform

Productsup’s integration enables brands to launch, list, and scale on Walmart Marketplace using the same feed management workflows they already rely on across every other channel

Productsup, the leading enterprise feed management and syndication platform, today announced it is an approved solution provider for Walmart Marketplace. The new integration gives Productsup customers a direct path to one of the fastest-growing ecommerce ecosystems in North America, without building or maintaining a custom API connection.

Walmart Marketplace offers an extensive ecommerce ecosystem with more than 120 million monthly shoppers. But with more than 6,700 product types, each with its own required and optional attributes, Walmart Marketplace’s listing requirements are strict and category-specific. Brands managing feeds manually or through custom-built connections often face slow onboarding, high rejection rates, and an ongoing maintenance burden that limits how quickly their catalog can scale.

“Walmart Marketplace is one of the most important growth channels in US ecommerce, seeing surging double-digit quarterly growth,” said Alan Turner, VP of Americas at Productsup. “While the audience and growth numbers are highly attractive, transitioning from a traditional wholesale retail model to a marketplace ecosystem requires a completely different operational playbook. Walmart Marketplace relies heavily on structured data and enforces strict rules that often trigger listing errors for legacy catalogs. Becoming an approved solution provider means our customers can activate Walmart Marketplace using the same catalog data, the same optimization tools, and the same platform they already use for dozens of other channels. There's no new system to learn and no custom integration to build.”

Productsup's integration automates the entire product-to-order lifecycle, offering:

• Category mapping: Category-specific attribute (CSA) templates ensure the right fields for Walmart Marketplace product categories are mapped and required attributes aren't missed, accelerating time-to-market.
• Smart listing detection: The integration automatically detects whether an item is a new listing, an update to an existing product, or fulfilled through Walmart Fulfillment Services, and routes it to the correct schema accordingly.
• Error prevention and resolution: Automated pre-submission checks catch missing or non-compliant data before it's sent, and clear, structured error messages replace Walmart Marketplace's CSV-based error files, showing sellers exactly which products failed and why. This makes troubleshooting faster and reduces time-to-resolution on listing issues.
• Price, inventory, and order sync: Price and inventory updates run through dedicated, high-frequency channels independent of full catalog runs, and order data, including shipment confirmations and cancellations, syncs directly with a brand's existing order management system.

The integration is built on the same enterprise-grade infrastructure that powers Productsup's existing channel network, extending the platform's data transformation, validation, and AI-powered enrichment tools to Walmart Marketplace. That gives brands already selling on Walmart Marketplace a way to replace manual spreadsheets and one-off API connections with automated feed management, and gives brands new to the platform a faster, more reliable path to launch. For Productsup's existing customers, activating Walmart Marketplace requires no new tooling, processes, or teams, turning an established feed management workflow into a new revenue channel.
