Asset Tree Service Overview¶

The asset tree service APIs provide management operations for asset trees, asset nodes, and asset paths. For more information on asset trees, see Asset Tree Overview.

The APIs in the asset tree service are some of the APIs EnOS provides that cover the core business processes of the system. For more information on EnOS APIs and the different APIs that EnOS provides, see About EnOS API.

For more information on how to invoke EnOS APIs, see Get Started with EnOS API.

Prerequisites¶

Ensure that you have read the limitations for asset trees. See Limitations.
