Steps

  1. Confirm the target: mercari.com (US consumer marketplace) has no public seller API - only unofficial scrapers exist
  2. Do not confuse it with Mercari Shops (api.mercari-shops.com), a real GraphQL API that serves only Japan's separate small-business storefront product with Japanese-language docs
  3. For US Mercari, plan on manual listing through the app since there is no documented bulk-listing or order-sync mechanism
  4. If a Japan-market integration is actually the goal, register through the Mercari Shops developer portal instead, which is a distinct product and account system
