public sealed class DnsAuthorization : IMessage<DnsAuthorization>, IEquatable<DnsAuthorization>, IDeepCloneable<DnsAuthorization>, IBufferMessage, IMessage
Reference documentation and code samples for the Certificate Manager v1 API class DnsAuthorization.
A DnsAuthorization resource describes a way to perform domain authorization
for certificate issuance.
Required. Immutable. A domain that is being authorized. A DnsAuthorization
resource covers a single domain and its wildcard, e.g. authorization for
example.com can be used to issue certificates for example.com and
*.example.com.
A user-defined name of the dns authorization. DnsAuthorization names must
be unique globally and match pattern
projects/*/locations/*/dnsAuthorizations/*.
