API v4 deprecations

Cloudflare occasionally makes updates to our APIs that result in behavior changes or deprecations. When this happens, we will communicate when the API will no longer be available and whether there will be a replacement.

​​ ChaCha20 TLS Cipher Removal

End of life Date: July 1st, 2023

Back in 2016, Cloudflare introduced support for ChaCha20-Poly1305 cipher suites for TLS 1.2.

At the time, we introduced two variants of these new suites, the “standard” suites as defined by the IETF RFC 7905, and “draft” suites that followed an earlier draft of said specification.

The draft suites were added for compatibility with some older Android devices that at the time did not yet support the proper ChaCha20-Poly1305 standard versions.

This was in 2016, and in the meantime the standard ChaCha20-Poly1305 cipher suites have gained much wider adoption, to the point were traffic using the old suites has dropped significantly.

Due to the current low usage and the non-standard nature of these cipher suites, we are now deprecating their support on the Cloudflare network.

This should not affect customer zones in any way, as clients that might currently use these cipher suites will be able to fallback to different ones.

In addition, unlike the standard variants, these legacy cipher suites are not exposed directly through our API (e.g. through the TLS cipher suites preferences endpoint), and their deprecation will not affect customer configurations in any way.

The ChaCha20-Poly1305 ciphers will be removed from Cloudflare on July 1st, 2023. If you have clients that use these ciphers you are advised to upgrade them to newer ciphers.

​​ Argo Tunnel

  • GET accounts/:account_identifier/tunnels
  • POST accounts/:account_identifier/tunnels
  • GET accounts/:account_identifier/tunnels/:tunnel_id
  • DELETE accounts/:account_identifier/tunnels/:tunnel_id

​​ Account Billing Profile, User Billing Profile, and User Billing History

​​ Load Balancing - notification_email

End of life date: April 3, 2023

This field is deprecated and has been moved to Cloudflare centralized notification service.

notification_email is the email address to send health status notifications to. This can be an individual mailbox or a mailing list. Multiple emails can be supplied as a comma delimited list.

​​ Transfer-Encoding and Content-Length headers

End of life date: July 1st, 2023

Previously, RFC 2616 allowed the use of Transfer-Encoding and Content-Length HTTP headers in the same request. RFC 7230 supersedes RFC 2616 and prohibits the use of Transfer-Encoding and Content-Length headers in the same request because they can cause HTTP request smuggling vulnerabilities.

Starting on July 1st, 2023, Cloudflare will decline requests with both Transfer-Encoding and Content-Length HTTP headers.
