description: 'Walmart publishes NO maintained first-party client library for the Marketplace, DSV or WFS APIs on any package
  registry. The only first-party SDKs that ever existed live in the walmartlabs GitHub organization and are both ARCHIVED
  and years stale: partnerapi_sdk_dotnet (last pushed 2020-08-14) and walmart-api (last pushed 2019-07-11). Neither was ever
  published to NuGet or npm under a Walmart-owned account. Walmart''s current position is code generation: its own docs point
  developers at OpenAPI Generator to build a typed client from the published spec, and the MCS Java OpenAPI Client Integration
  Guide (February 2026) is a step-by-step generator recipe rather than a shipped library. Every installable Walmart client
  on a registry today is third-party, and the most-used one has not shipped since 2022.'
official_sdk_count: 0
official_note: 'official_sdk_count is 0 deliberately: the two first-party repositories are archived and unpublished, so a
  consumer cannot install a Walmart-authored client from any registry.'

  note: First-party Walmart Partner API SDK for .NET. ARCHIVED and read-only; never published to NuGet under a Walmart account,
    so there is no registry metadata endpoint and version is null. Six years stale against a v3/v4 API that shipped a release
    note as recently as 2026-08-20.

  note: First-party wrapper for the (retired) public Walmart Labs Open API. ARCHIVED; not on npm under a Walmart account,
    so version is null. Wraps a product Walmart no longer operates.

  version: 3.0.1
  published: '2022-12-14'
  note: Third-party. Types generated from Walmart's published OpenAPI. Last release 2022-12-14 — roughly four years behind
    the current spec, which has had weekly changelog entries throughout 2025 and 2026.

  version: null
  published: null
  note: Third-party PHP SDK covering Marketplace Partner, Content Provider and 1P Supplier APIs for US/CA/MX. Packagist metadata
    endpoint returned 404 for both the v1 and p2 paths on 2026-08-27, so version and published are null — checked, nothing
    recordable.

  position: Walmart directs developers to generate a client from its OpenAPI rather than shipping one.
