Overview

The Get Node Parents endpoint allows you to discover all parent nodes directly connected to a specific child node in your graph. This operation is essential for understanding hierarchical relationships, analyzing tree structures, and building comprehensive parent-child relationship maps.

Key capabilities include:

Finding all parent nodes connected to a specific child node
Analyzing hierarchical relationship patterns and tree structures
Discovering all nodes that are direct ancestors of the child node
Building hierarchical node profiles and relationship maps
Supporting tree traversal and hierarchical path analysis

Get Node Parents

Retrieve all parent nodes connected to a specific child node using GET: /v1.0/tenants/{tenant-guid}/graphs/{graph-guid}/nodes/{node-guid}/parents. This endpoint returns all nodes that are direct parents of the specified child node, allowing you to analyze hierarchical relationships and understand the tree structure of your graph.

curl --location 'http://localhost:8701/v1.0/tenants/00000000-0000-0000-0000-000000000000/graphs/00000000-0000-0000-0000-000000000000/nodes/00000000-0000-0000-0000-000000000000/parents' \

Best Practices

When retrieving node parents, consider the following recommendations:

Validate Node GUID: Ensure the child node GUID exists before making requests
Handle Empty Results: Implement proper handling for nodes with no parents

Next Steps

After retrieving node parents, you can:

Analyze hierarchical relationship patterns and tree structures
Build comprehensive hierarchical node profiles and relationship maps
Implement tree traversal algorithms for hierarchical path analysis
Create hierarchical node visualization interfaces
Perform tree structure analysis and organizational studies
Develop hierarchical recommendation systems and relationship discovery
