Cloudflare Fundamentals - Service Key authentication deprecated

Service Key authentication for the Cloudflare API is deprecated. Service Keys will stop working on September 30, 2026. API Tokens replace Service Keys with fine-grained permissions, expiration, and revocation. What you need to do Replace any use of the X-Auth-User-Service-Key header with an API Token scoped to the permissions your integration requires. If you use cloudflared , update to a version from November 2022 or later. These versions already use API Tokens. If you use origin-ca-issuer , update to a version that supports API Token authentication. For more information, refer to API deprecations .
