New: Marketplace API Deprecation Guide

Date: March 11, 2026

We have published a new API Deprecation Guide for Walmart Marketplace APIs. The guide clearly defines Legacy, Deprecated, and Sunset stages and introduces a centralized lifecycle status and timeline table to provide consistent visibility into deprecation schedules and migration paths.

What changed

  • Added: A new API Deprecation Guide for Walmart Marketplace
  • Added: Standard lifecycle definitions (Legacy, Deprecated, Sunset)
  • Added: A centralized API lifecycle status and timeline table
  • Standardized: Deprecation and sunset communication across Marketplace APIs

Why it matters

  • Provides greater clarity into API lifecycle stages
  • Provides published deprecation and sunset timelines
  • Improves visibility into upcoming integration updates

Next steps

  • Review the API lifecycle status and timeline table
  • Identify APIs your integration currently calls that are marked as Legacy or Deprecated
  • Update your integration to use the listed migration path before the sunset date
  • Validate changes in a sandbox or non-production environment
