Sell on Walmart Marketplace

Walmart Marketplace Connector

Walmart Marketplace is one of the most influential e-commerce platforms in the world, offering retailers a powerful opportunity to expand into the highly competitive U.S. market.

Backed by the scale and reputation of Walmart, the marketplace provides sellers with access to a vast customer base, strong brand trust, and significant online retail traffic. With more than 425 million monthly visitors across Walmart’s digital ecosystem, the platform enables businesses to increase product visibility, accelerate sales growth, and strengthen their presence in North America.

Our Walmart Marketplace integration app is designed to simplify and streamline multichannel commerce operations. The solution connects your existing e-commerce platform — including Shopify, BigCommerce, and other leading systems — directly with Walmart Marketplace, enabling seamless synchronisation of product listings, inventory levels, pricing updates, and order management in real time.

By automating these critical processes, businesses can reduce manual administration, improve operational efficiency, and minimise the risk of overselling or pricing inconsistencies across channels.

Full range of Walmart Marketplace services

Our advanced multichannel API enables businesses to efficiently manage catalogue data, inventory, pricing, and orders across Walmart Marketplace in real time. Automated synchronisation improves operational efficiency, reduces manual workload, and helps maintain accurate marketplace performance and compliance.

Following Walmart Marketplace account approval, our experienced onboarding team provides dedicated support to ensure a smooth integration and launch process. We assist with listing optimisation, marketplace best practices, and operational setup to help retailers maximise performance and drive long-term growth on the platform.

ChannelUnity Reviews

Obsessed Merch

" Absolutely Fantastic service! I have been using Channel Unity to integrate my POD and Physical Stock products to many different Etsy, eBay and Amazon channels for just over a year now and it has been great!
Channel unity gives you all the marketplace fields you need to make data rich product listings on all channels and with the use of the 'Tag product fields' feature you can build a tag to relate to data you need to be on a certain field in a marketplace and then add the tag in bulk to all the relevant Shopify listings within the Shopify bulk editor. This truly is a powerhouse system that is rock solid. "
