services, if the destinationGroups contain vCenter.

| Name | Description | Type | Notes |
|---|---|---|---|
| _create_time | Timestamp of resource creation | EpochMsTimestamp | Readonly Sortable |
| _create_user | ID of the user who created this resource | string | Readonly |
| _last_modified_time | Timestamp of last modification | EpochMsTimestamp | Readonly Sortable |
| _last_modified_user | ID of the user who last modified this resource | string | Readonly |
| _links | References related to this resource The server will populate this field when returing the resource. Ignored on PUT and POST. |
array of ResourceLink | Readonly |
| _protection | Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity. |
string | Readonly |
| _revision | Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected. |

| _schema | Schema for this resource | string | Readonly |
| _self | Link to this resource | SelfResourceLink | Readonly |
| _system_owned | Indicates system owned resource | boolean | Readonly |
| children | Subtree for this type within policy tree Subtree for this type within policy tree containing nested elements. Note that this type is applicable to be used in Hierarchical API only. |
array of ChildPolicyConfigResource Children are not allowed for this type |
|
| constraint_expression | Expression to constrain the target attribute value. This property is deprecated. Please use the "constraint_expressions" property instead to specify one or more constraint expressions. If this property is populated, then the "constraint_expressions" value is ignored. |

| description | Description of this resource | string | Maximum length: 1024 Sortable |
| display_name | Identifier to use when displaying entity in logs or GUI Defaults to ID if not set |
string | Maximum length: 255 Sortable |
| id | Unique identifier of this resource | string | Sortable |
| marked_for_delete | Indicates whether the intent object is marked for deletion Intent objects are not directly deleted from the system when a delete is invoked on them. They are marked for deletion and only when all the realized entities for that intent object gets deleted, the intent object is deleted. Objects that are marked for deletion are not returned in GET call. One can use the search API to get these objects. |
boolean | Readonly Default: "False" |
| message | User friendly message to be shown to users upon violation. | string | |
| origin_site_id | A unique identifier assigned by the system for knowing which site owns an object This is a UUID generated by the system for knowing which site owns an object. This is used in NSX+. |
string | Readonly |
| overridden | Indicates whether this object is the overridden intent object Global intent objects cannot be modified by the user. However, certain global intent objects can be overridden locally by use of this property. In such cases, the overridden local values take precedence over the globally defined values for the properties. |
boolean | Readonly Default: "False" |
| owner_id | A unique identifier assigned by the system for the ownership of an object This is a UUID generated by the system for knowing who owns this object. This is used in NSX+. |
string | Readonly |
| parent_path | Path of its parent Path of its parent |
string | Readonly |
| path | Absolute path of this object Absolute path of this object |
string | Readonly |
| realization_id | A unique identifier assigned by the system for realizing intent This is a UUID generated by the system for realizing the entity object. In most cases this should be same as 'unique_id' of the entity. However, in some cases this can be different because of entities have migrated their unique identifier to NSX Policy intent objects later in the timeline and did not use unique_id for realization. Realization id is helpful for users to debug data path to correlate the configuration with corresponding intent. |
string | Readonly |
| relative_path | Relative path of this object Path relative from its parent |
string | Readonly |
| remote_path | Path of the object on the remote end. This path is populated only in case of multi-site scenario. Currently it is supported only for LM objects. When LM is onboarded to multi-site platform like NAPP or GM, remote_path will be set to the globally unique path across multi-site topology . It is generated based on local site-name and uses /org tree namespace. Note: It is populated only for LM objects. Not supported on the GM. |
string | Readonly |
| resource_type | Must be set to the value Constraint | string | |
| tags | Opaque identifiers meaningful to the API user | array of Tag | Maximum items: 30 |
| target | Target resource attribute details. This property is deprecated. Please use the "targets" property instead to specify one or more targets. If this property is populated, then the "targets" value is ignored. |
ConstraintTarget | Deprecated |
| target_owner_type | Constraint target's owner type | string | Enum: GM, LM, ALL |
| targets | Collection of target resources attribute details. | array of ConstraintTarget | |
| unique_id | A unique identifier assigned by the system This is a UUID generated by the GM/LM to uniquely identify entities in a federated environment. For entities that are stretched across multiple sites, the same ID will be used on all the stretched sites. |
string | Readonly |
