This takes care of automatic replication of the content of all zones and the default name servers for newly create zones, before a zone can be replicated it needs to be provisioned in our platform with the IP address of your server as master. To create (and delete) zones you have multiple options:

1. Create and delete the zones manually trough our portal
2. Automate the creation and deletion the zones in your backoffice software using our API
3. Automation based on hooks, we do not have an example for this available. cPanel has no unified hooks for creation/deletion of zones. At least the following hooks need to be considered
   1. Whostmgr->Accounts::Create
   2. Whostmgr->Accounts::Remove
   3. cPanel->Api2::AddonDomain::addaddondomain
   4. cPanel->Api2::AddonDomain::deladdondomain
