How to edit a DNS zone using the WHM API?

Introduction

Editing DNS zones can be done using the WHM API using the ediitzonerecord API call.

Procedure

First, you need to use the dumpzone APII call  line number of the record, in this example, I am looking for  the A record for example.com::

-bash-4.2# whmapi1 dumpzone domain=example.com
----SNIP----
 -
 Line: 15
 address: 10.2.32.170
 class: IN
 name: example.com.
 ttl: 14400
 type: A
----SNIP---

Now I use the ediitzonerecord to make the change:

whmapi1 editzonerecord domain=example.com line=15 name=example.com. class=IN ttl=86400 type=A address=192.168.0.20
