Domains and DNS

Change a domain's settings

PATCH/api/v1/domains/:domain

Who can use this: Site adminsAs Markdown

Send only what you want to change; the rest stays as it is. The answer is the domain's settings afterwards.

Parameters

Name	Where	What it is
domain required	path	The domain name.e.g. example.com
mail_enabled	body	Accept mail for the domain.e.g. true
dns_managed	body	Whether its DNS zone is kept here. Only the setting changes; no zone is created or removed.
active	body	false turns the whole domain off, as Disable a domain does; true turns it back on.

Good to know

A domain that isn't listed answers 404.
