As Walmart’s supplier ecosystem continues to evolve, APIs and integrations have become a major focus. These connections allow suppliers to easily automate reporting, track performance in real-time, and stay in sync with Walmart's ever-changing digital environment.
While tech terminology may feel intimidating at first, these tools run behind the scenes and can save countless hours—while preventing manual errors. Let’s break down how to access them and what platforms suppliers should know.
Accessing APIs through Retail Link and Supplier One
For those who are unfamiliar, an API (or application programming interface) is a set of rules that allow software programs to communicate with each other.
Retail Link houses complete datasets—in theory, but much of that information can feel buried or require multiple reports in order to utilize it. Fortunately, Walmart now provides more direct access to the same data through the use of integrations, APIs, and supporting platforms.
To access API options:
Login to Retail Link
Navigate to Supplier One
On left-hand menu, select Apps and Integrations
This section connects suppliers to Walmart’s broader digital ecosystem. Here, suppliers can find documentation and links to approved integration partners that securely sync internal systems with Walmart.

Accessing APIs through Scintilla
Scintilla is another gateway for API access. It provides direct access to Walmart’s data pipelines and connects supplier systems to sales, replenishment, and operational data.
Scintilla offers two tier levels:
Tier | Access | Best For |
Scintilla Basic | Limited self-serve data | Most suppliers and those just getting started |
Scintilla Charter (Paid) | Expanded API tools and deeper data pipelines | Advanced analytics and automation teams |
Scintilla Basic supports suppliers by enabling:
Automated data pulls for sales and inventory
PO and item data syncing into internal platforms
Deduction and replenishment data integration
Scintilla Charter includes all features of Scintilla Basic, as well as:
API access for automating data transfer to third-party platforms
Online Pickup and Delivery Data
Advanced data for more detailed data sets, such as POs, OTIF (On-Time, In-Full), and customer insights
Report Customization for more granular customization and sharing
Pro Tip: If setup feels too technical, suppliers can lean on Walmart approved integrators who specialize in the onboarding and API configuration process.
Integrations
Walmart does a respectable job of organizing the options within Supplier One, outlining the steps for connection, as well as maintaining that connection.
Common integrations include:
Accenture Song: brand strategy, marketing, and e-commerce
OptiWise: helps brands and retailers increase online sales
Geek Seller: manages sales across online platforms as well as in-store
Syndigo: manages and distributes product information and digital assets
In addition to those partners, several platforms support Retail Link, Supplier One, and EDI automation. The following are three widely used options.
SPS Commerce
SPS Commerce offers phenomenal solutions for suppliers working with Walmart, such as:
EDI compliance: optimizes data transfer for purchase orders, invoices, shipping notices, and other critical documents
Item setup: includes item setup for sale on both Walmart's online and in-store platforms
Order fulfillment: centralizes order management from various channels—including e-commerce and in-store.
Automation: reduces manual data entry and streamlines tasks like order and invoice management
Supply chain performance suite: optimizes supply chain by providing suppliers with access to point-of-sale data
DSV certification: for suppliers in the Drop Ship Vendor (DSV) program, SPS Commerce offers testing and certifying EDI or XML connections before Walmart activates a seller account.
Revenue Recovery: helps suppliers by reclaiming lost revenue from deductions, chargebacks, and retailer fines
HighRadius
HighRadius is an account receivables software available for account reconciliation, bank reconciliation, and transaction matching.
This platform supports suppliers with:
Credit Issues: prioritizing credit reviews & auto-sending decision correspondence
Billing: automated daily review of revenue reconciliation
Cash Applications: data capture & matching algorithms to achieve higher automation rates for same-day cash application
Collections: automates accruals, streamlines tasks, and flags anomalies
ReadyCloud
ReadyCloud enables suppliers to manage shipping, marketing, and returns more efficiently. While Retail Link offers these same services, ReadyCloud may help suppliers streamline operations through its integrations with various sales channels and order management systems.
Shipping: automations and money-saving features; built for growing businesses
Warehouse Operations: manages shipments across various carriers
Automation: options include batch shipping and scan-to-print

While Retail Link offers visibility into data, these platforms are a game changer for suppliers as they help bring more control and greater efficiency to working with Walmart’s supply chain.

Key Takeaways
Retail Link provides suppliers with access to Walmart data and workflows, but Supplier One and Scintilla offer more modern automation and deeper data connectivity. Suppliers should evaluate internal reporting needs, data volume, and resource capacity before selecting integration platforms for the best fit.
Approved integration partners can play a key role in keeping systems synced and in reducing errors. Many suppliers choose a full-service integration provider such as SPS Commerce to manage deductions, ensure compliance, and streamline financial processes.
Ultimately, the right combination of Retail Link tools, API access, and integrations can support cleaner records, fewer deductions, faster insights, and scalable growth.
