Overview

Walmart Connect supports two Display advertising solutions:

Onsite Display — ads served on Walmart-owned properties such as Walmart.com and the Walmart app
Offsite Display (Walmart DSP) — ads served across the open web, gaming environments, and other offsite inventory

Understanding the difference between these solutions is important because API capabilities vary by solution.

Understanding Walmart Display solutions

Onsite Display

Walmart-owned inventory

Onsite Display runs on Walmart-owned properties and uses an auction model to help advertisers bid on available inventory, launch campaigns, and optimize delivery.

Served on Walmart.com and in the Walmart app
Supports campaign management workflows
Supports creative creation and moderation workflows
Supports near-real-time reporting through the Stats API
Supports finalized performance reporting through Snapshot APIs

Offsite Display

Walmart DSP inventory

Offsite Display extends Walmart audience and measurement capabilities beyond Walmart-owned properties, helping advertisers reach customers across offsite channels.

Powered by Walmart DSP
Extends reach across open web, social, CTV, gaming, and more
Supports reporting and measurement workflows
Campaign management and creative APIs are not supported
Availability varies by report type

How Onsite Display works

Onsite Display uses an auction-based model.

Advertisers define a bid, budget, flight dates, and targeting strategy. Walmart then evaluates available inventory and serves ads when the campaign is eligible to compete in auction.

Common use cases include:

Always-on campaigns
New product launches
Audience expansion
Bid strategy testing
In-flight optimization

Onsite Display is the solution to use when partners need to manage campaigns, creatives, audiences, and delivery reporting through the API.

How Offsite Display works

Offsite Display, powered by Walmart DSP, extends Walmart audience capabilities beyond Walmart-owned properties.

It is designed for advertisers who want to:

Reach customers across the open web
Extend campaigns into gaming and other offsite environments
Measure performance using reporting endpoints
Understand how offsite media influences online and in-store outcomes

Offsite Display is the solution to use when partners need reporting and measurement support, but not campaign management or creative workflows.
