Walmart Drop Ship Vendor (DSV)

Walmart Drop Ship Vendor (DSV) is Walmart's program for first-party suppliers who hold inventory in their own warehouses and ship directly to Walmart customers when an order is placed on Walmart.com. Walmart owns the listing, the customer relationship, and the order routing; the vendor owns the inventory, the fulfillment, and the SLA performance that protects their seller scorecard.

Hopstack's integration with Walmart Drop Ship Vendor automates the entire vendor fulfillment workflow, from receiving purchase orders to acknowledging them, shipping with box-level tracking, and keeping inventory and catalog in sync, so your warehouse team can focus on picking, packing, and shipping instead of toggling between Supplier One and the WMS.

‍

Who Should Use This Integration?

• Walmart 1P Vendors: Brands and manufacturers selling wholesale to Walmart who need to fulfill DSV orders efficiently from their own warehouses without manual order entry or chargeback exposure.
• 3PLs Serving Walmart Vendors: Third-party logistics providers handling fulfillment on behalf of Walmart DSV clients who need per-client, per-warehouse isolation with separate credentials and ship nodes.
• Multi-Warehouse Vendors: Vendors operating multiple fulfillment centers under different Walmart ship nodes who want orders to automatically route to the correct warehouse without manual sorting.
• Multi-Channel Sellers: Vendors running Walmart DSV alongside other channels such as Amazon Vendor Direct Fulfillment, Shopify, and EDI retail who want a single WMS to manage every fulfillment workflow with the same operational rigor.

Key Features

‍

Automated Purchase Order Sync

• Hands-Free Order Import: Purchase orders from Walmart Supplier One are automatically pulled into Hopstack every 15 minutes. No manual downloads, CSV uploads, or Supplier One logins required.
• Smart Duplicate Prevention: Orders that have already been imported are automatically skipped, so your team never processes the same order twice.
• Status-Based Filtering: Choose which orders to import based on their Walmart status, giving you full control over what enters the fulfillment pipeline.
• Auto-Acknowledgment: Walmart requires DSV orders to be acknowledged within a tight window. With auto-acknowledge enabled, every new order is acknowledged on Walmart the moment it lands in Hopstack, eliminating the most common source of acknowledgment-related chargebacks. Manual acknowledgment is also supported for vendors who prefer human review.

Ship Confirmation with Box-Level Tracking

• Automatic Ship Confirmation: When an order ships from Hopstack, ship confirmation is pushed back to Walmart automatically with carrier name, service method, tracking number, and ship date.
• Box-Level Tracking: For multi-box shipments, tracking is reported at the box level rather than collapsed into a single number, so Walmart and the end customer see accurate per-box delivery progress.
• Carrier Method Mapping: Hopstack carriers and service levels are automatically mapped to Walmart's required carrier method codes, so the right carrier and service show up on Walmart without any manual translation.
• Cancellation Workflow: Cancellations from the warehouse floor flow back to Walmart with a structured cancellation reason, keeping order status accurate and protecting the vendor's seller scorecard.

‍

Catalog and Inventory Sync

• Automated Catalog Sync: Walmart product items are pulled into Hopstack every two hours and mapped to your product catalog automatically.
• Smart Product Identifiers: Each Walmart item is mapped using a combined GTIN and SKU identifier, so catalogs containing multiple SKUs under a shared GTIN do not collapse into a single product record.
• Inventory Push by Ship Node: Hopstack pushes inventory levels back to Walmart by GTIN and ship node, supporting both single-node and multi-node vendor configurations.
• Clean Multi-Facility Allocation: Vendors operating multiple fulfillment facilities under separate ship nodes get isolated inventory updates per location, with no risk of one facility's inventory leaking into another's allocation.

‍

Multi-Ship-Node and Multi-Tenant Support

• Per-Ship-Node Setup: Walmart DSV scopes orders, inventory, and product publishing by ship node. Each warehouse maps to its own integration bound to a specific Walmart ship node, so orders are pulled, fulfilled, and confirmed against the right facility from the start.
• No Custom Routing Layer: There are no mapping tables to maintain and no custom routing code to break. The integration uses Walmart's native ship node model as the source of truth.
• 3PL Multi-Client Isolation: Each vendor client can be set up as an independent integration, keeping credentials, ship nodes, orders, and operations cleanly separated across the 3PL's customer base.
• Sandbox and Production: Hopstack supports both Walmart's sandbox and production environments. Vendors can validate the full integration end to end in sandbox before flipping to live operations.

‍

How It Works

‍

The integration connects Hopstack to Walmart Supplier One on the Walmart Marketplace v3 API and automates the full order-to-ship cycle.

• Walmart issues a DSV purchase order through Supplier One and routes it to the appropriate ship node based on inventory and customer geography.
• Hopstack polls Walmart every 15 minutes, picks up the new order, and creates it in the WMS with full line items, customer shipping address, and requested carrier method.
• If auto-acknowledge is enabled, the order is acknowledged on Walmart automatically the moment it lands in Hopstack.
• Your warehouse team fulfills the order using Hopstack's standard pick, pack, and ship workflow.
• On dispatch, Hopstack pushes a ship confirmation back to Walmart with box-level tracking, carrier name, service method, and ship date.
• For multi-ship-node setups, each warehouse only sees the orders Walmart has assigned to its ship node.

‍

What Data Gets Synced

• Purchase Orders: Purchase Order ID, Customer Order ID, order date, ship-by dates, line items including SKU, GTIN, quantity, and requested carrier method.
• Shipping Address: End customer delivery address for each direct fulfillment order.
• Product Catalog: Walmart items synced every two hours and mapped to Hopstack products via combined GTIN and SKU identifiers.
• Inventory Levels: Inventory pushed back to Walmart by GTIN and ship node, with single-node and multi-node support.
• Ship Confirmations: Carrier name, service method, tracking number, and ship date pushed back at the box level when available.
• Order Acknowledgments and Cancellations: Accept, ship, and cancel statuses with structured cancellation reasons, communicated back to Walmart in real time.

Getting Started

Setting up the Walmart Drop Ship Vendor integration takes just a few minutes per ship node.

You'll need:

• Walmart Supplier One (Drop Ship Vendor) account
• Walmart Marketplace API credentials (Client ID and Client Secret) with DSV scope
• Walmart Ship Node ID for each fulfillment location

Once credentials are ready, the Hopstack onboarding team configures the integration, runs an initial product and order backfill, and validates the full workflow in sandbox before going live.

‍

Important Considerations

• One integration is required per Walmart ship node.
• Ship node IDs must match exactly between Hopstack and Walmart Supplier One.
• The integration is polling-based: orders sync every 15 minutes and the product catalog syncs every 2 hours.
• Always test in the Walmart sandbox before going live in production.
• Product catalog should be set up before activating the integration so order line items map cleanly to Hopstack products.
• API credentials can expire and should be monitored.
