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.

​​ Auto Minify

End of life date: August 5th, 2024

The Auto Minify API endpoints are deprecated, since the Auto Minify feature was deprecated.

Deprecated APIs:

  • GET /zones/:zone_id/settings/minify
  • PATCH /zones/:zone_id/settings/minify

​​ Mobile Redirect

End of life date: June 30th, 2024

This endpoint and its related APIs are deprecated in favor of Single Redirects. Refer to Perform mobile redirects to migrate Mobile Redirect to Redirect Rules.

Deprecated API:

  • GET /zones/:zone_identifier/settings/mobile_redirect
  • PATCH /zones/:zone_identifier/settings/mobile_redirect

Replacement: Single Redirects

​​ Brotli

End of life date: June 14th, 2024

The Brotli setting and its API endpoints are deprecated. After the end of life date, Brotli compression will be enabled by default for all zones.

Deprecated APIs:

  • GET /zones/:zone_id/settings/brotli
  • PATCH /zones/:zone_id/settings/brotli

Enterprise customers can override Cloudflare’s default compression behavior using Compression Rules.

​​ Server-side Excludes

End of life date: June 14th, 2024

The Server-side Excludes feature and its API endpoints are deprecated.

Deprecated APIs:

  • GET /zones/:zone_id/settings/server_side_exclude
  • PATCH /zones/:zone_id/settings/server_side_exclude

End of life date: May 31st, 2024

The name of an SRV record normally consists of three parts: the service (e.g., _xmpp), the protocol (e.g., _tcp), and the base name (example.com). The complete name would then be, e.g., _xmpp._tcp.example.com.

When interacting with DNS records through the API, SRV records contain both a full name as well as a data map containing the individual components of the name:

{
  "name": "_xmpp._tcp.example.com",
  "data": {
    "service": "_xmpp",
    "proto": "_tcp",
    "name": "example.com",
    ...
  },
  ...
}

We are deprecating the service, proto and name fields within the data map in favor of the name field outside the data map, which is the same name field that’s used by all other record types.

Before the end of life date, please ensure that:

  • when reading SRV records, you use only the name outside of the data map and ignore service, proto and name within the data map if they exist; and
  • when writing SRV records, you set the name outside of the data map and do not set service, proto or name within the data map.

After the end of life date, the API will stop producing the service, proto and name data fields, and if any of them are received from a client, an error will be returned.

This deprecation does not affect other SRV data fields not mentioned above (priority, weight, port, target) or data fields for any other record type other than SRV.

Modified API:

  • GET /zones/:zone_id/dns_records
  • POST /zones/:zone_id/dns_records
  • GET /zones/:zone_id/dns_records/:dns_record_id
  • PATCH /zones/:zone_id/dns_records/:dns_record_id
  • PUT /zones/:zone_id/dns_records/:dns_record_id

​​ Firewall Rules API and Filters API

End of life date: May 1st, 2024

The Firewall Rules API and the Filters API are deprecated, since Firewall Rules was deprecated in favor of WAF custom rules. Refer to Firewall Rules to WAF custom rules migration for more information about this change.

Deprecated APIs:

​​ WAF managed rules APIs (previous version)

End of life date: May 1st, 2024

  • POST /zones/:zone_id/rate_limits
  • GET /zones/:zone_id/rate_limits/:rate_limit_id
  • PUT /zones/:zone_id/rate_limits/:rate_limit_id
  • DELETE /zones/:zone_id/rate_limits/:rate_limit_id

Replacement: Rate limiting rules (new version)

​​ Privacy Pass API Removal

End of life date: March 31st, 2024

In 2017 Cloudflare announced support for Privacy Pass, a recent protocol to let users prove their identity across multiple sites anonymously without enabling tracking. The initial use case was to provide untraceable tokens to sites to vouch for users who might otherwise have been presented with a CAPTCHA challenge. In the time since this release, Privacy Pass has evolved both at the IETF and within Cloudflare. The version announced in 2017 is now considered legacy, and these legacy Privacy Pass tokens are no longer supported as an alternative to Cloudflare challenges. As has been discussed on our blog The end road for CAPTCHA, Cloudflare uses a variety of signals to infer if incoming traffic is likely automated. The (legacy) Privacy Pass zone setting is no longer meaningful to Cloudflare customers as Cloudflare now operates CAPTCHA free, and supports the latest Privacy Pass draft. In September 2023 support for legacy Privacy Pass tokens as an alternative to Cloudflare Managed Challenge was removed. By the end of March 2024, the current public-facing API will be removed as well.

Deprecated API:

  • GET zones/:zone_identifier/settings/privacy_pass
  • POST zones/:zone_identifier/settings/privacy_pass

​​ Argo Tunnel

End of life Date: February 4th, 2024

This endpoint and its related APIs are deprecated in favor of the Cloudflare Tunnels equivalent APIs.

Deprecated API:

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

Replacement: Cloudflare Tunnel API

​​ 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.

As of July 1st, 2023, the ChaCha20-Poly1305 ciphers have been deprecated and are deemed End of Life by Cloudflare. If you have clients that currently rely on these ciphers, it is strongly recommended to upgrade them to newer, more secure ciphers. Be aware that these deprecated ciphers will be completely removed in the first quarter of 2024, and requests using them will start to fail. Take proactive measures to ensure a smooth transition and maintain the security of your systems.

​​ 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.

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

End of life date: June 6th, 2023

There is no API replacement for these endpoints. As an alternative, please log in to your Cloudflare account to view your:

Deprecated API:

  • GET accounts/{account_identifier}/billing/profile
  • GET user/billing/profile
  • GET user/billing/history

​​ Load Balancing - notification_email

End of life date: April 3rd, 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.

​​ Access Bookmark applications

End of life date: March 19th, 2023

This endpoint is deprecated in favor of using a specialized Access Application App Type API.

Deprecated API:

  • GET accounts/:identifier/access/bookmarks
  • GET accounts/:identifier/access/bookmarks/:uuid
  • POST accounts/:identifier/access/bookmarks/:uuid

Replacement: POST accounts/:account_identifier/images/v2/direct_upload

​​ Zone Analytics API
