There are generally 3 APIs to be aware of when working with tree nodes. Each API covers slightly different use cases. Those use cases are outlined in this document.

CRUD on tree nodes

This is the most general use case, where an integration is managing the tree node definitions.

This requires the Editor_SystemTools_Metadata role.

There are 6 endpoints to be aware of here.

Response properties

Name	Type	Description

`treeNodeId`	int	A language-independent id for this tree node.
`optionValue`	string	A language-independent string value for this tree node.
`parentId`	int/null	The `treeNodeId` of the parent node of this node. Or `null` if the node doesn’t have a parent.
`sortIndex`	int	A value indicating how this node should be sorted in relation to all other tree nodes.
`metaFieldId`	int	The metafield id of the tree metafield this node belongs to.
`itemId`	int	The itemId of the tree node.
`itemGuid`	string/guid/uuid	The itemGuid of the tree node.
`labels`	dictionary	The translations of this tree node. The key is the languageId.
`labels.label`	string	The title/name/label of the tree node in this language.
`labels.languageId`	int	The language id of this translation.
`labels.treeValueId`	int	The language specific id of this tree node.

Get a specific tree node

URL: /digizuitecore/legacyservice/api/admin/tree-nodes/{treeNodeId}

Method: GET

Auth required: YES

Request:

GET https://<my-dam>/digizuitecore/legacyservice/api/admin/tree-nodes/1
Authorization: AccessKey MIIC...dEK

Response

Create a new tree node

URL: /digizuitecore/legacyservice/api/admin/tree-nodes

Method: POST

Auth required: YES

This api is also available as a bulk variant, that takes an array of the objects described here: /digizuitecore/legacyservice/api/admin/tree-nodes/bulk-create

Request parameters:

Name	Type	Description

Name	Type	Description
`optionValue`	string	A language-independent string value for this tree node.
`parentId`	int/null	The `treeNodeId` of the parent node of this node. Or `null` if the node doesn’t have a parent.
`sortIndex`	int	A value indicating how this node should be sorted in relation to all other tree nodes.
`metaFieldId`	int	The metafield id of the tree metafield this node belongs to.
`accessRightsMode`	enum, string, one of: CalculateAutomatically DoNothing	Controls how access rights/item security is created when this tree node is created. CalculateAutomatically: Security is inherited from either the parent tree node, or if not available, the metafield. DoNothing: No item security is created for this tree node, which means nobody can access it. If you use this, you should make sure to create item security entries yourself. If not specified, CalculateAutomatically will be used.
`labels`	array of object	The translations that should be created for this object.
`labels.languageId`	int	The id of the language this translation is for.
`labels.label`	string	The language specific translation of this value.

Get tree nodes for tree to display

URL:

/digizuitecore/legacyservice/api/tree/nodes/metafield/{metafieldId}
/digizuitecore/legacyservice/api/tree/nodes/metafield/{metafieldId}/assignable
/digizuitecore/legacyservice/api/tree/nodes/metafield/{metafieldItemGuid}
/digizuitecore/legacyservice/api/tree/nodes/metafield/{metafieldItemGuid}/assignable

Method: GET

Auth required: YES

This gets the tree nodes which the authorized user has access to based on item security. It is available in two flavors. One which returns everything the user has read access to and the /assignable variant of the endpoint which returns everything the user has write access to. The difference between the two is what the user can assign to an asset and what the user can see as assigned on the asset.

The tree nodes in the response is sorted such that they can be rendered straight to a screen without doing any additional sorting.

Request parameters:

Name	Type	Description

Name	Type	Description
metafieldId	int	The metafield id of the tree metafield to fetch nodes for.
metafieldItemGuid	string/guid/uuid	The itemGuid of the tree metafield to fetch nodes for.

Response properties:

Name	Type	Description

Name	Type	Description
`treeNodeId`	int	A language-independent id for this tree node.
`optionValue`	string	A language-independent string value for this tree node.
`parentId`	int/null	The `treeNodeId` of the parent node of this node. Or `null` if the node doesn’t have a parent.
`sortIndex`	int	A value indicating how this node should be sorted in relation to all other tree nodes.
`metaFieldId`	int	The metafield id of the tree metafield this node belongs to.
`itemId`	int	The itemId of the tree node.
`itemGuid`	string/guid/uuid	The itemGuid of the tree node.
`labels`	dictionary	The translations of this tree node. The key is the languageId.
`labels.label`	string	The title/name/label of the tree node in this language.
`labels.languageId`	int	The language id of this translation.
`labels.treeValueId`	int	The language specific id of this tree node.
`depth`	int	Indicates how many labels deep this node is. Very useful for rendering the tree nodes in a tree like structure.
`hasChildren`	bool	If this node has any childn nodes. Useful foro
