Name	Type	Description
`Property`	Object	The entire GTM property configuration.
`backupCName`	String	Specifies a `backupCName`. If GTM declares that all of the servers configured for your property are down, and you configured a `backupCName`, then queries for the property return the `backupCName`. If a `backupCName` is set, don't set a `backupIp`.
`backupIp`	String	Specifies a backup IP. When GTM declares that all of the targets are down, it hands out the `backupIP`. The IP type coincides with the property's `iPv6` setting. If a `backupIp` is set, don't set a `backupCName`.
`balanceByDownloadScore`	Boolean	Indicates whether download score based load balancing is enabled. GTM estimates the load on your data centers based on how long they take to respond to GTM liveness tests. The advantage: you don't need to implement a load object. The disadvantage: it's a very crude measure of load, and usually highly nonlinear. As load increases, download times don't increase significantly, until there's too much load. When that happens, the download times skyrocket. This can easily cause erratic load balancing or load oscillations.
`cname`	String	Indicates the fully qualified name aliased to a particular property. The public name of the property.
`comments`	String	Provides information about the purpose of the property.
`dynamicTTL`	Integer	Indicates the TTL in seconds for records that might change dynamically based on liveness and load balancing such as A and AAAA records, and CNAMEs. The value ranges from `30` to `3600` and can change on request. The default is `60`.
`failbackDelay`	Integer	Specifies the failback delay in seconds. The minimum value is `0`. If specified, when a server has been down and comes back up, (that is, its liveness test starts succeeding again), GTM only considers it up after the failback delay has elapsed and tests continue to succeed.
`failoverDelay`	Integer	Specifies the failover delay in seconds. The minimum value is `0`. If specified, when a server begins failing its liveness test, GTM only considers it down after the failover delay has elapsed and the errors persist.
`ghostDemandReporting`	Boolean	From v1.3. Enables reporting of unmet content requests received by edge servers, analyzing demand for unserved content.
`handoutLimit`	Integer	From v1.3. Indicates the limit for the number of live IPs handed out to a DNS request. The `handoutLimit` applies only if `handoutMode` is set to either `normal` or `persistent` for the property. If applicable, the `handoutLimit` default value is `8` or `null` if not.
`handoutMode`	String	Specifies how IPs are returned when more than one IP is alive and available. Either `normal`, `persistent`, `one-ip`, `one-ip-hashed`, or `all-live-ips`. The default is `normal`. Handout mode is relevant only when you have more than one server IP in a data center.
`healthMax`	Number	Defines the absolute limit beyond which IPs are declared unhealthy. If backup CNAMEs are provided for a property, then it's reasonable for all IPs to be declared unhealthy. The `healthMax` value is multiplied by the smaller of the `timeoutPenalty` and the `errorPenalty`. This check declares as down any server with a score greater than this product. The default value is `null`.
`healthMultiplier`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. The cutoff is computed from the minimum score across all data centers, for a given property and two object members: `healthMultiplier` and `healthThreshold`. The cutoff is either `healthMultiplier` (default value: 1.5) times the minimum score, or the `healthThreshold` (default value: 4), whichever is greater. See also `healthThreshold` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`healthThreshold`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. See also `healthMultiplier` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`ipv6`	Boolean	Indicates the type of IP address handed out by a property. A `true` value indicates that all IP addresses specified are IPv6, and all hostnames need to resolve to AAAA records. A `false` value indicates IPv4 addresses, and all hostnames need to resolve to A records.
`lastModified`	String	An ISO 8601 timestamp that indicates when the property was last changed.
`links`	Array	A URL path that allows direct navigation to the property.
`links[]`	Object	Lists navigable URLs to resources.
`livenessTests`	Array	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`livenessTests[]`	Object	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.
`mapName`	String	A descriptive label for a geographic map or a CIDR map that's required if the property is either `geographic` or `cidrmapping`, in which case `mapName` needs to reference either an existing geographic map or CIDR map in the same domain.
`maxUnreachablePenalty`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers show an aggregated loss fraction higher than the penalty value. The penalty value is either `maxUnreachablePenalty` (minimum value is `0` and the default is `null`) or `unreachableThreshold` (decimal between `0` and `1`. A value of 1.0 or `null` disables an unreachable penalty). See also `unreachableThreshold` within this object.
`minLiveFraction`	Number	From v1.3. Specifies what fraction of the servers need to respond to requests so GTM considers the data center up and able to receive traffic. For example, if your data center contains eight servers, and the `minLiveFraction` value is `0.5`, then at least four servers need to respond to requests. Conversely, if five servers are down, and three servers are up, then GTM considers the entire data center down. Optional when a `minLiveFraction` value exists or not `null`.
`mxRecords`	Array	Specifies the MX records handed out to `MX` record type queries. Note that mapping and liveness testing aren't done. The same MX records are handed out for every request.
`mxRecords[]`	Object
`name{Hostname}`	String	The hostname.
`name{apex}`	String	The APEX name.
`scoreAggregationType`	String	Specifies how GTM aggregates liveness test scores across different tests, when multiple tests are configured. Values are `mean`, `median`, `best`, or the default `worst`.

`staticRRSets[]`	Object	From v1.4. TBD.
`staticTTL`	Integer	Specifies the TTL in seconds for static resource records that don't change based on the requesting name server IP. This includes MX, TXT, and SPF records.

The value ranges from `0` to `30000`. See also `stickinessBonusPercentage` within this object. To learn more about how these object members relate to each other, see API concepts.
`stickinessBonusPercentage`	Integer	Specifies a percentage used to configure data center affinity. This only applies if the property `type` is `performance` and the domain `type` is `full`. The value ranges from `0` to `100`. See also `stickinessBonusConstant` within this object. To learn more about how these object members relate to each other, see API concepts.
`trafficTargets`	Array	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.
`trafficTargets[]`	Object	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.

See API versioning for more information.
`unreachableThreshold`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers have an aggregated loss fraction higher than this value. The value is a decimal between `0` and `1`. A value of `1.0` or `null` disables an unreachable penalty. See also `maxUnreachablePenalty` within this object.

`handoutMode`	String	Specifies how IPs are returned when more than one IP is alive and available. Either `normal`, `persistent`, `one-ip`, `one-ip-hashed`, or `all-live-ips`. The default is `normal`. Handout mode is relevant only when you have more than one server IP in a data center.
`healthMax`	Number	Defines the absolute limit beyond which IPs are declared unhealthy. If backup CNAMEs are provided for a property, then it's reasonable for all IPs to be declared unhealthy. The `healthMax` value is multiplied by the smaller of the `timeoutPenalty` and the `errorPenalty`. This check declares as down any server with a score greater than this product. The default value is `null`.
`healthMultiplier`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. The cutoff is computed from the minimum score across all data centers, for a given property and two object members: `healthMultiplier` and `healthThreshold`. The cutoff is either `healthMultiplier` (default value: 1.5) times the minimum score, or the `healthThreshold` (default value: 4), whichever is greater. See also `healthThreshold` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.

If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.

`resourceType`	String	From v1.3. Specifies the query type, if `testObjectProtocol` is `DNS`. Types include: `A`, `AAAA`, `AFSDB`, `CNAME`, `HINFO`, `LOC`, `MX`, `NAPTR`, `NS`, `PTR`, `RP`, `SOA`, `SPF`, `SRV`, `SSHFP`, `TXT`, `DNSKEY`, `DS`, `NSEC3`, `NSEC3PARAM`, or `RRSIG`. Additional support for unknown types `TYPENNNNN` where `NNNNN` is an integer from `1` through `65535`.
`responseString`	String	Specifies a response string. Required if `testObjectProtocol` is `tcp` or `tcps`. Maximum 4000 characters.
`sslClientCertificate`	String	Indicates a Base64-encoded certificate. SSL client certificates are available for `livenessTests` that use secure protocols.
`sslClientPrivateKey`	String	Indicates a Base64-encoded private key. The private key used to generate or request a certificate for `livenessTests` can't have a passphrase nor be used for any other purpose.
`testInterval`	Integer	Indicates the interval at which the liveness test is run, in seconds. Requires a minimum of 10 seconds.
`testObject`	String	Specifies the static text that acts as a stand-in for the data that you're sending on the network.
`testObjectPassword`	String	Specifies the test object's password. It's required if `testObjectProtocol` is `ftp`. Maximum is 128 characters.
`testObjectPort`	Integer	Specifies the port number for the `testObject`. Value from `1` to `65535`.
`testObjectProtocol`	String	Specifies the test protocol. Either `DNS`, `DOH`, `DOT`, `HTTP`, `HTTPS`, `HTTP2`, `HTTP2S`, `FTP`, `POP`, `POPS`, `SMTP`, `SMTPS`, `TCP`, or `TCPS`. To enable `testObjectProtocol` for `DNS`, `DOH`, or `DOT` requires `application/vnd.config-gtm.v1.3+json`.
`testObjectUsername`	String	A descriptive name for the `testObject`. If `testObjectProtocol` is `ftp`, then you need to specify a `testObjectUsername`. The value is a maximum of 256 non-space, alphanumeric characters.
`testTimeout`	Number	Specifies the duration of the liveness test before it fails. The range is from `0.001` to `60` seconds.
`timeoutPenalty`	Number	From v1.2. Specifies the score reported if the liveness test times out. This is independent of the liveness `testTimeout` value. The default value is `25` seconds.
`Property.resource.livenessTests[].httpHeaders[]`
`name`	String	From v1.4. Name of the HTTP header.
`value`	String	From v1.4. Value of the HTTP header.
`Property.resource.mxRecords[]`
`exchange`	String	MX record exchange member.
`preference`	Number	MX record preference field.
`Property.resource.staticRRSets[]`
`rdata`	Array	From v1.4. An array of data strings, representing multiple records within a set. The format of the `rdata` strings are dependent on the `type` of this record.
`ttl`	Integer	From v1.4. The number of seconds that this record should live in a resolver's cache before being refetched.
`type`	String	From v1.4. The record type.
`Property.resource.trafficTargets[]`
`datacenterId`	Integer	A unique identifier for an existing data center in the domain.
`enabled`	Boolean	Indicates whether the traffic target is used. You can also omit the traffic target, which has the same result as the `false` value. However, when the value is `false`, GTM continues to store the other traffic target fields in the database. There's no need to store them locally should you want to use the traffic target at a later time.
`handoutCName`	String	Specifies an optional data center for the property. Uses the `handoutCName` when there are no servers configured for the property. Maximum 63 characters for the labels, 255 characters overall. May contain alphanumeric, hyphens, and underscores, but not literal IP addresses. Leading or trailing hyphens aren't allowed.
`name`	String	An alternative label for the traffic target.
`precedence`	Number	From v1.6. For use by `ranked-failover` type properties, the lower the number, the higher the precedence.
`servers`	Array	Identifies the IP address or the hostnames of the servers. For hostnames that return IP addresses, tests all IP addresses for liveness.
`weight`	Number	Specifies the traffic weight for the target. This is required when the enclosing property is `failover`, `weighted`, `weighted-with-load-feedback`, or `performance`. The sum of this value, for all enabled targets, can be any number, percentage, or ratio. For example, you can express a traffic split as 60/40, 120/80, or 3/2, all equivalent values. For `failover` properties, set this value to `1` for the traffic target you want to mark as primary.
`Property.status`
`changeId`	String	A unique identifier generated when a change occurs to the domain. The maximum length is 36 characters.
`links`	Array	Specifies the URL path that allows direct navigation to the domain.
`links[]`	Object	Lists navigable URLs to resources.
`message`	String	A notification generated when a change occurs to the domain. The maximum length is 4000 characters.
`passingValidation`	Boolean	Indicates if the domain validates.
`propagationStatus`	String	Tracks the status of the domain's propagation state. Either `PENDING`, `COMPLETE`, or `DENIED`. A `DENIED` value indicates that the domain configuration is invalid, and doesn't propagate until the validation errors are resolved.
`propagationStatusDate`	String	An ISO 8601 timestamp indicating when a change occurs to the domain.
`Property.status.links[]`
`href`	String	Provides a hypermedia link to the complete URL that uniquely defines a resource.
`rel`	String	Indicates the link relationship of the object.
