Documented steps

  1. Cloudflare deprecated the legacy Workers KV namespace routes under /accounts/{account_id}/workers/namespaces/* (deprecated 2026-07-15, end of life 2026-10-15).
  2. Legacy routes: GET/POST /accounts/{account_id}/workers/namespaces (list/create), GET/PUT/DELETE .../namespaces/{namespace_id} (get/rename/remove), GET .../namespaces/{namespace_id}/keys (list keys), GET .../metadata/{key_name} (read metadata), GET/PUT/DELETE .../values/{key_name} (read/write/delete KV pairs).
  3. Replacement: identical endpoints under /accounts/{account_id}/storage/kv/namespaces/* — same request params, same response payloads.
  4. Migration: swap the URL path prefix from /workers/namespaces/ to /storage/kv/namespaces/ in each call; no other change needed.
  5. Audit any hardcoded Cloudflare Workers KV management URLs, SDK wrappers, or automation and update the paths before the 2026-10-15 end-of-life date, after which the legacy routes stop working.
