Each entry is a table of API / change type / release date / description, and descriptions are written at operation and property granularity ("Added optional query parameter ean in GET /v3/items/walmart/search"), which makes them diffable against the OpenAPI. Separate changelogs exist for the Advertising Partners (13 entries) and Suppliers (11 entries) programs. scheme: dated release notes, roughly weekly current_version: v3 (v4 on newer WFS inbound-shipment endpoints) url: https://developer.walmart.com/us-marketplace/changelog entry_count_published: 51 window: 2026-01-29 through 2026-08-20 (22 most recent entries recorded here) other_changelogs: - program: Advertising Partners url: https://developer.walmart.com/advertising-partners/changelog entry_count: 13 - program: Suppliers (1P) url: https://developer.walmart.com/suppliers/changelog entry_count: 11 - program: Advertising Partners Search url: https://developer.walmart.com/advertising-partners-search/changelog entry_count: 2 announcement_pages: note: Walmart also publishes long-form "What's new" announcement pages under /us-marketplace/page/, including dated Item Spec version updates and deprecation notices. url: https://developer.walmart.com/us-marketplace/page/introducing-walmart-marketplace-api-changelogs entries: - version: august-20-2026-release date: '2026-08-20' url: https://developer.walmart.com/us-marketplace/changelog/august-20-2026-release apis: - On-request Reports - Items change_types: - Added highlights: - Added enum values CONTENT_QUALITY and LISTING_QUALITY to reportType across the eight /v3/reports operations - Added optional query parameters ean and isbn to GET /v3/items/walmart/search breaking: false - version: august-6-2026-release date: '2026-08-06' url: https://developer.walmart.com/us-marketplace/changelog/august-6-2026-release apis: - Insights change_types: - Added highlights: - Added optional query parameter conditionType to GET /v3/insights/performance/returns/report and /summary - Added optional response property payload/conditionType on the returns summary 200 breaking: false - version: july-30-2026-release date: '2026-07-30' url: https://developer.walmart.com/us-marketplace/changelog/july-30-2026-release apis: - Items - Bulk Item Setup - Feeds - On-request Reports - Orders - Insights change_types: - Added - Changed highlights: - Virtual pack support added across POST /v3/items/spec, GET /v3/items, GET /v3/items/{id} and the MP_VIRTUAL_PACK_BUNDLE feed type - Orders miscAttributes changed from object to oneOf with a discriminator, and required properties details and name were REMOVED — a response-shape change across all seven order operations - Added optional query parameters inDemandIndicator and isCustomerFavorite on Insights breaking: false note: The Orders miscAttributes change removes previously-required properties and introduces a discriminator;
