TFS 2017 | TFS 2015 | TFS 2013

Note

Looking for REST APIS that support TFS 2018 or later versions? See the Azure DevOps REST API Reference.

api-version = 1.0

All work items have an area and an iteration field. The values that these fields can have are defined in the classification hierarchies.

If you haven't already, look at the information on getting started with these APIs.

Get a list of classification nodes

GET https://{instance}/DefaultCollection/{project}/_apis/wit/classificationnodes/{nodeType}/[{nodePath}]?api-version={version}[&$depth={int}]

Property	Type	Description
URL
instance	string	TFS server name ({server:port}).
project	string	Name or ID of a project that contains the classification nodes.
nodeType	enum {areas, iterations}	The type of classification node you are trying access.
nodePath	string	Path of the classification node.
Query
api-version	string	Version of the API to use.
$depth	int	Depth of children to retrieve.
