It cannot place or follow orders, and the Checkout API needs separate approval. The documentation renders only in a browser, and the API terms date from 2020 and still name a previous affiliate network.\n\n**Walmart Agent Gateway.** Walmart has published terms for agents shopping its sites, including customer approval of purchases by default, no access to payment cards and blocking of agents that break them. The gateway is a beta by request for companies and developers, with no public endpoint, documentation, tool list or price, and Agent Profiles are announced for about November 2026.\n\n## Before you call either\n\n### Walmart Affiliate Marketing API\n\n1. Generate a fresh WM_SEC.AUTH_SIGNATURE for each call, because a signature older than 180 seconds is rejected\n2. Keep below 5,000 calls a day per application\n3. Pass the Impact publisher ID so returned links earn commission\n4. Hand purchases to the person through the returned product link, since the affiliate API cannot check out\n\n### Walmart Agent Gateway\n\n1. Don't look for a public endpoint; Walmart hasn't published one, and the gateway starts as a beta for approved companies and developers\n2. Ask your human for approval before any Walmart purchase; Walmart's terms require it by default and block agents that act beyond the shopper's intent\n3. Don't request or store the customer's card details; Walmart's terms bar agents from payment-card data and payment-method changes\n4. Treat claims that ChatGPT, Gemini or Muse already connect through the gateway as Reuters's reporting; Walmart's own post doesn't say so\n\n## Questions\n\n### Which is better for AI agents, Walmart Affiliate Marketing API or Walmart Agent Gateway?\n\nWalmart Affiliate Marketing API scores 38.6 (E) on agent readiness against Walmart Agent Gateway's 8.3 (F), and leads in every scored category.\n\n### Do Walmart Affiliate Marketing API and Walmart Agent Gateway need an API key?\n\nWalmart Affiliate Marketing API needs an API key.
