Cloudflare retires CIDR route endpoints and removes Tunnel connections from list and get responses

On 5 October 2026, Cloudflare removes CIDR-encoded Zero Trust route endpoints and the connections array from Cloudflare Tunnel and Mesh list and get responses.

Cloudflare TunnelZero TrustroutesconnectionsAPI removal

Previous state

Route create, update and delete calls could encode the CIDR in the URL, and tunnel or mesh list/get responses included a connections array.

Current state

Routes use standard route_id endpoints and connection detail must be fetched from dedicated per-tunnel connections endpoints.

Who needs to care

API clients, dashboards and automation managing private routes or parsing Cloudflare Tunnel and Mesh connection details.

What to do

Migrate route operations to route_id endpoints and query the dedicated connections endpoint before 5 October 2026.

What the source does not prove

The API shape changes do not remove existing routes or tunnels, and Cloudflare says cloudflared and its Terraform provider do not read the removed connections field.

Lifecycle history

Dated event sequence

  1. Breaking changes announced

    Cloudflare published the endpoint and response-field retirement plan.
