PUBLIC EVIDENCE
The public-evidence count is not a coverage limit. Every listed article carries its own last-verified date; the current verification index shows the latest date on each public article.
COVERAGE · SEVEN AREAS
Where the work actually lives.
Supplier work spans specifications, item setup, compliance, payments, reporting, and advertising. Retail Reason helps connect that work across Walmart, Sam’s Club, Marketplace, Walmart Connect, and ProSpec. Ask in website chat or a supported assistant, with the right operating context for each question.
THE COVERAGE MAP
Start with the operating area, then follow the evidence.
The coverage map separates supplier, data, club, Marketplace, advertising, and specification work. Available guidance follows the access and selling channel of your selected workspace.

Technical workflows and APIs
ADVERTISING, SPECIFICATIONS, AND TECHNICAL WORK
The operating question does not stop at the portal.
Use Walmart Connect guidance for supplier or Marketplace advertising, ProSpec guidance for supplier specifications, and technical guidance for supported APIs. These examples illustrate the questions to work through; they are not customer results.
ILLUSTRATIVE PATH · WALMART CONNECT
ROAS fell. Should we reduce bids?
Not from ROAS alone. First separate the reporting window, attribution view, availability, Buy Box, conversion, targeting, placement, and budget conditions that can move the result.
Website chat can review the campaign exports you upload and prepare findings with recommended checks. Retail Reason does not inspect a live campaign, retrieve advertising data, or change a bid.
ILLUSTRATIVE PATH · PROSPEC
A specification needs updating. What should we check?
Establish the product, specification stage, available records, and what changed. Separate confirmed information from missing evidence before preparing the next steps.
Website chat can review authorized specification files and prepare a review tracker. Retail Reason does not access ProSpec, edit records, approve specifications, or certify compliance.
ILLUSTRATIVE PATH · API WORK
An API request started failing. Do we change the payload?
Not until the failure class is clear. Identify the endpoint, environment, status code, request identifier, authentication state, and current rate-limit or retry signals before rewriting a previously accepted payload.
Retail Reason can explain supported APIs and troubleshoot from the details you provide. It does not call retailer APIs, hold retailer credentials, or execute the fix.
SAM’S CLUB, IN ITS OWN OPERATING CONTEXT
A separate supplier relationship.
Sam’s Club has its own supplier agreement, vendor number, merchant teams, systems and scorecards. Retail Reason treats Sam’s Club as its own operating context, not as a Walmart channel filter. Dedicated coverage includes supplier onboarding, item data, MADRID, MAP, deductions, DSV, merchandising, packaging, OTIF and compliance. Sam’s Club coverage is currently less broad and has been tested against fewer representative questions than Walmart coverage; see limitations.
PUBLIC-ARTICLE SUMMARY · SAM’S CLUB DATA QUESTION
Where Sam’s Club data actually lives.
A dual-banner supplier reaches both sides through related account infrastructure, yet the data stays tied to the banner and vendor number, so the complete answer routes each kind of Sam’s question to the system that owns it.
If you need both, you need both entitlements. Plan for two access paths; one does not unlock the other.
MARKETPLACE GUIDANCE
A Marketplace example.
Marketplace guidance accounts for settlement structure, fees, and timing. Here is one example from a public article:
PUBLIC-ARTICLE SUMMARY · MARKETPLACE QUESTION
Why doesn’t my Walmart Marketplace payout match my sales?
Because the settlement data lives at two different grains (order lines and itemized amount-type rows), and summing across the wrong one is the classic reconciliation trap. Walmart-funded promotions and withheld facilitator tax make correct charges look wrong, and the payout cycle’s timing makes a correct deposit look short.
Diagnostic path · THREE CHECKS
CHECK 1
Stay at the order-line grain and sum Payable to Partner from Sale once per line. Do not multiply summary values across itemized amount-type rows.
CHECK 2
Compare the deposit with its settlement cycle, not a sales-dashboard period. Post-shipment holds can push an order into a later payout.
CHECK 3
Subtract statement-level reserves, Marketplace Capital repayment, and lines whose hold had not cleared by the cycle boundary. The remainder should tie to the bank deposit.
The full tie-out, including withheld facilitator tax and promotion treatment, is in the public article.
