What is Walmart Marketplace EDI Integration?

Walmart Marketplace EDI Integration is the automated exchange of X12 electronic documents between a seller's backend ERP and Walmart's platform. It orchestrates inbound Purchase Orders (850), outbound Ship Notices (856), Invoices (810), and Inventory updates (846) via AS2, SFTP, or VAN, replacing manual processes to ensure real-time order-to-cash visibility and strict trading partner compliance.

Walmart Marketplace EDI COMPLIANCE

Where do Walmart Marketplace integrations usually get stuck?

Most compliance issues arise when business operations and EDI mapping are handled separately, breaking critical document flows.

01

How do mismatched 850 segments cause shipment delays?

Incorrect N1 loop mapping leads to wrong ship-to location data, causing carrier reroutes and missed delivery promises.

02

Why are 856 ASNs rejected after fulfillment?

Missing packing slip hierarchy or SSCC-18 codes triggers immediate Walmart validation failures and non-compliance charges.

03

How does batch processing break inventory sync?

Delayed 846 updates create oversold products, increasing order cancellations and damaging seller performance metrics.
