Code Examples

Downloading Root Objects

HTTP

POST <CONTENT-PATH>/UBIKContent.svc/GetHierarchyDeltasV212/<APP>/<CTX>/<TOKEN>/<VERSION> HTTP/1.1
Host: <HOSTNAME/IP>:<PORT>
Content-Type: application/json

{
"StartingPoint": {
"__type": "HierarchyRoot:#UBIK.Service.DTO.V211"
},
"ParentDepth": 0,
"ChildrenDepth": 1,
"KnownRelations": null,
"KnownContents": null
}

Make sure to replace the <tags> accordingly!

The __type property allows the JSON deserializer to find the correct class. [Microsoft Documentation].
