## Deprecate legacy Workers KV namespace API routes

Jul 15, 2026 

[ KV ](https://edgetunnel-b2h.pages.dev/kv/) 

The legacy Workers KV API routes under `/accounts/{account_id}/workers/namespaces/*` are deprecated as of July 15, 2026, and will stop working on October 15, 2026\. Migrate to the documented [Workers KV API](https://edgetunnel-b2h.pages.dev/api/resources/kv/) routes under `/accounts/{account_id}/storage/kv/namespaces/*` before that date.

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 `/workers/namespaces/` to `/storage/kv/namespaces/`.

#### What you need to do

Update any integration that calls a route under `/accounts/{account_id}/workers/namespaces/` to use the equivalent route under `/accounts/{account_id}/storage/kv/namespaces/`. The migration is a direct URL path substitution — request parameters and response payloads are identical:

* `GET` and `POST /accounts/{account_id}/workers/namespaces` → `GET` and `POST /accounts/{account_id}/storage/kv/namespaces`
* `GET`, `PUT`, and `DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}` → `GET`, `PUT`, and `DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}`
* `GET /accounts/{account_id}/workers/namespaces/{namespace_id}/keys` → `GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/keys`
* `GET /accounts/{account_id}/workers/namespaces/{namespace_id}/metadata/{key_name}` → `GET /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/metadata/{key_name}`
* `GET`, `PUT`, and `DELETE /accounts/{account_id}/workers/namespaces/{namespace_id}/values/{key_name}` → `GET`, `PUT`, and `DELETE /accounts/{account_id}/storage/kv/namespaces/{namespace_id}/values/{key_name}`
