Cloudflare retires legacy Registrar domain-management API endpoints

Cloudflare will remove the legacy endpoints for listing, retrieving and updating Registrar domains after 27 September 2026 and directs integrations to the newer Registrar API surface.

Cloudflare Registrardomain APIendpoint retirementmigrationdeadline

Previous state

Registrar integrations used legacy domain list, get and update endpoints.

Current state

Integrations must map workflows to the new domain search, availability-check and registration API surfaces.

Who needs to care

Domain-management automation and platform teams using Cloudflare Registrar APIs.

What to do

Inventory legacy endpoint calls, map non-equivalent operations and test the newer API before the cutoff.

What the source does not prove

The replacement is not a one-for-one path rename. Cloudflare does not state one exact post-cutoff HTTP error or a direct equivalent for every update operation.
