If you wish to use your existing domain as the main realm for the platform you will need to add a new subdomain, this is also referred to as the resource name at HighQ. The subdomain can go to multiple levels. Most commonly a two-level subdomain is used i.e.
platform.clientname.com
. It is also possible to go to multiple levels but it is generally best practice to limit to the third subdomain i.e.
uk.platform.clientname.com
