public sealed class Registration : IMessage<Registration>, IEquatable<Registration>, IDeepCloneable<Registration>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Domains v1 API class Registration.
The Registration resource facilitates managing and configuring domain name
registrations.
There are several ways to create a new Registration resource:
To create a new Registration resource, find a suitable domain name by
calling the SearchDomains method with a query to see available domain name
options. After choosing a name, call RetrieveRegisterParameters to
ensure availability and obtain information like pricing, which is needed to
build a call to RegisterDomain.
Another way to create a new Registration is to transfer an existing
domain from another registrar. First, go to the current registrar to unlock
the domain for transfer and retrieve the domain's transfer authorization
code. Then call RetrieveTransferParameters to confirm that the domain is
unlocked and to get values needed to build a call to TransferDomain.
public ContactSettings ContactSettings { get; set; }
Required. Settings for contact information linked to the Registration. You cannot
update these with the UpdateRegistration method. To update these
settings, use the ConfigureContactSettings method.
Settings controlling the DNS configuration of the Registration. You
cannot update these with the UpdateRegistration method. To update these
settings, use the ConfigureDnsSettings method.
public ManagementSettings ManagementSettings { get; set; }
Settings for management of the Registration, including renewal, billing,
and transfer. You cannot update these with the UpdateRegistration
method. To update these settings, use the ConfigureManagementSettings
method.
public ContactSettings PendingContactSettings { get; set; }
Output only. Pending contact settings for the Registration. Updates to the
contact_settings field that change its registrant_contact or privacy
fields require email confirmation by the registrant_contact
before taking effect. This field is set only if there are pending updates
to the contact_settings that have not been confirmed. To confirm the
changes, the registrant_contact must follow the instructions in the
email they receive.
