KV - Deprecate legacy Workers KV namespace API routes

<p>The legacy Workers KV API routes under <code>/accounts/{account_id}/workers/namespaces/*</code> are deprecated as of July 15, 2026, and will stop working on October 15, 2026. Migrate to the documented <a href="https://developers.cloudflare.com/api/resources/kv/">Workers KV API</a> routes under <code>/accounts/{account_id}/storage/kv/namespaces/*</code> before that date.</p> <p>The legacy and replacement routes are interchangeable. They accept the same request parameters and return the same response payloads. To migrate, update the URL path from <code>/workers/namespaces/</code> to <code>/storage/kv/namespaces/</code>.</p> <div tabindex="-1" class="heading-wrapper level-h4"><h4 id="what-you-need-to-do">What you need to do</h4><a class="anchor-link" href="#what-you-need-to-do"><span aria-hidden="true" class="anchor-icon"><svg width="16" height="16" viewBox="0 0 24 24"><path fill="currentcolor" d="m12.11 15.39-3.88 3.88a2.52 2.52 0 0 1-3.5 0 2.47 2.47 0 0 1 0-3.5l3.88-3.88a1 1 0 0 0-1.42-1.42l-3.88 3.89a4.48 4.48 0 0 0 6.33 6.33l3.89-3.88a1 1 0 1 0-1.42-1.42Zm8.58-12.08a4.49 4.49 0 0 0-6.33 0l-3.89 3.88a1 1 0 0 0 1.42 1.42l3.88-3.88a2.52 2.52 0 0 1 3.5 0 2.47 2.47 0 0 1 0 3.5l-3.88 3.88a1 1 0 1 0 1.42 1.42l3.88-3.89a4.49 4.49 0 0 0 0-6.33ZM8.83 15.17a1 1 0 0 0 1.1.22 1 1 0 0 0 .32-.22l4.92-4.92a1 1 0 0 0-1.42-1.42l-4.92 4.92a1 1 0 0 0 0 1.42Z"></path></svg></span></a></div> <p>Update any integration that calls a route under <code>/accounts/{account_id}/workers/namespaces/</code> to use the equivalent route under <code>/accounts/{account_id}/storage/kv/namespaces/</code>. The migration is a direct URL path substitution — request parameters and response payloads are identical:</p> <ul> <li><code>GET</code> and <code>POST /accounts/{account_id}/workers/namespaces</code> → <code>GET</code> and <code>POST /accounts/{account_id}/storage/kv/namespaces</code></li> <li><code>GET</code>, <code>PUT</code>, and <code>DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}</code> → <code>GET</code>, <code>PUT</code>, and <code>DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}</code></li> <li><code>GET /accounts/{account_id}/workers/namespaces/{namespace_id}/keys</code> → <code>GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/keys</code></li> <li><code>GET /accounts/{account_id}/workers/namespaces/{namespace_id}/metadata/{key_name}</code> → <code>GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/metadata/{key_name}</code></li> <li><code>GET</code>, <code>PUT</code>, and <code>DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}/values/{key_name}</code> → <code>GET</code>, <code>PUT</code>, and <code>DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}</code></li> </ul> <p>For more information about the deprecation timeline, refer to <a href="https://developers.cloudflare.com/fundamentals/api/reference/deprecations/">API deprecations</a>.</p>
