Acenda maps your catalog to Walmart's listing requirements, keeps inventory and pricing in sync, and routes every Walmart order to the right fulfillment destination — all from the same platform that runs your other channels.
Walmart is the largest retail marketplace after Amazon, and one of the few channels where brands can run both models at once — selling as a 3P seller on the Walmart Marketplace and supplying Walmart directly as a 2P dropship vendor (DSV). Acenda supports both from one catalog, one inventory pool, and one order queue.
2P — Dropship
✓Full EDI and API order, inventory, and shipment automation for Walmart DSV.
✓Purchase orders, acknowledgements, ASNs, and invoices exchanged automatically.
✓Routing rules send each order to the right warehouse or 3PL.
✓Compliance-ready documents and labels generated to Walmart’s spec.
3P — Marketplace
✓Seller account status, item health, and listing quality monitored in one dashboard.
✓Catalog mapping to Walmart’s taxonomy, with attribute rules per category.
✓Full seller capabilities: pricing, promotions, fulfillment settings, and repricing inputs.
✓Walmart Canada supported as a separate channel on the same catalog.
Product syndication
Direct, real-time catalog syndication over Walmart’s API.
✓Product data, variants, images, and attributes publish straight to Walmart with no flat files.
✓Category-specific attribute requirements are mapped and validated before submission.
✓Price and content changes propagate continuously, not on a nightly batch.
✓Rejections surface with the exact field and reason, with AI-assisted remediation.
Order, inventory & shipment (OIS)
✓Orders drop from Walmart into Acenda automatically, normalized alongside every other channel.
✓Real-time inventory updates push back on a continuous cycle, so oversells are prevented across channels.
✓Shipment confirmations and tracking numbers feed back to the channel in the required format.
✓Cancellations, adjustments, and returns are reconciled without manual re-entry.
How do I connect Walmart Marketplace to Acenda?
You add Walmart US (or Walmart WFS) in Acenda Admin, enter your Seller Center Client ID and Client Secret, and then authorize Acenda on Walmart.
Go to CHANNELS > Integrations, click New in Sales Channels, select Walmart US (or Walmart WFS) and click Add. If Walmart isn't listed, contact Acenda Support to add a Walmart install to your plan.
Open the integration > Settings > Authorization, enter the Client ID and Client Secret from Walmart Seller Center and click Save.
Open Settings > Consent, click Start OAuth Consent Flow, sign in to Walmart and click Authorize.
Back in Acenda, confirm the Consent section says "Consent has already been given." and the integration shows no red warning icon.
Use Functionality Control to choose which syncs run and Inventory Control to set an inventory floor. Allow about an hour for the first updates.
Your catalog is mapped to Walmart's categories and attribute requirements, validated before submission, and kept current as requirements change.
Inventory & pricing sync
Stock levels and prices stay in sync with your other channels, with safety stock buffers to protect against overselling.
Orders & fulfillment
Walmart orders route automatically to your warehouse, 3PL, or fulfillment partner, with tracking sent back to Walmart.
