Cloudflare retires legacy Workers KV namespace API routes on 15 October 2026
Cloudflare will stop serving the legacy /workers/namespaces route family on 15 October 2026 and directs integrations to the equivalent /storage/kv/namespaces routes.
Previous state
Workers KV integrations could call namespace endpoints below the legacy /workers/namespaces path.
Current state
Clients must use /storage/kv/namespaces; request parameters and response payloads remain interchangeable.
Affected users
Who needs to care
Developers, automation owners and platform teams calling the legacy Workers KV namespace routes.
Required response
What to do
Inventory legacy route calls, replace the path prefix, and test create, list, get and delete workflows before the cutoff.
Evidence boundary
What the source does not prove
The change retires route paths rather than the KV namespace resource model. Cloudflare states that parameters and payloads remain interchangeable, but does not prove that every third-party client has migrated.
