API Reference

List Objects

GET/api/v2/ontologies/{ontology}/objects/{objectType}

Lists the objects for the given Ontology and object type.

Note that this endpoint does not guarantee consistency. Changes to the data could result in missing or repeated objects in the response pages.

For Object Storage V1 backed objects, this endpoint returns a maximum of 10,000 objects. After 10,000 objects have been returned and if more objects are available, attempting to load another page will result in an ObjectsExceededLimit error being returned. There is no limit on Object Storage V2 backed objects.

Each page may be smaller or larger than the requested page size. However, it is guaranteed that if there are more results available, at least one result will be present in the response.

Note that null value properties will not be returned.

Third-party applications using this endpoint via OAuth2 must request the following operation scope: api:ontologies-read.

Path parameters

ontology

string

The API name of the ontology. To find the API name, use the List ontologies endpoint or check the Ontology Manager.

objectType

string

The API name of the object type. To find the API name, use the List object types endpoint or check the Ontology Manager.

Query parameters

pageSize

integer

optional

The desired size of the page to be returned. Defaults to 1,000. See page sizes for details.

pageToken

string

optional

The page token indicates where to start paging. This should be omitted from the first page's request. To fetch the next page, clients should take the value from the nextPageToken field of the previous response and use it to populate the pageToken field of the next request.

select

list<SelectedPropertyApiName>

optional

The properties of the object type that should be included in the response. Omit this parameter to get all the properties.

Show child attributes

SelectedPropertyApiName

string

By default, anytime an object is requested, every property belonging to that object is returned. The response can be filtered to only include certain properties using the properties query parameter.

Properties to include can be specified in one of two ways.

A comma delimited list as the value for the properties query parameter properties={property1ApiName},{property2ApiName}
Multiple properties query parameters. properties={property1ApiName}&properties={property2ApiName}

The primary key of the object will always be returned even if it wasn't specified in the properties values.

Unknown properties specified in the properties list will result in a PropertiesNotFound error.

To find the API name for your property, use the Get object type endpoint or check the Ontology Manager.

orderBy

string

optional

A command representing the list of properties to order by. Properties should be delimited by commas and prefixed by p or properties. The format expected format is orderBy=properties.{property}:{sortDirection},properties.{property}:{sortDirection}...

By default, the ordering for a property is ascending, and this can be explicitly specified by appending :asc (for ascending) or :desc (for descending).

Example: use orderBy=properties.lastName:asc to order by a single property, orderBy=properties.lastName,properties.firstName,properties.age:desc to order by multiple properties. You may also use the shorthand p instead of properties such as orderBy=p.lastName:asc.

artifactRepository

string

optional

The repository associated with a marketplace installation.

packageName

string

optional

The package name of the generated SDK.

excludeRid

boolean

optional

A flag to exclude the retrieval of the __rid property. Setting this to true may improve performance of this endpoint for object types in OSV2.
