Warning:
The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

Warning:

Note:

On servers that run CentOS 7, you may see a `named` warning about the absence of SPF resource records on DNS.

- This warning is **not** relevant on CentOS 7 servers, because
RFC 7208 deprecated SPF
records. CentOS 7 servers use
TXT records instead of SPF records.
- Red Hat 7.1 and CentOS 7.1 both contain `bind-9.9.4-23.el7`, which is an updated version of BIND that complies with RFC 7208. To resolve this issue, update your operating system to a version that contains the updated version of BIND. For more information, read the Red Hat Bugzilla case about SPF record errors.

cPanel Tag System (deprecated)

Warnings:
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.
