2.5.1 Retrieving Device Hierarchy Information That Has Changed
To retrieve device hierarchy information that has changed, the DeviceGroupHierarchy GET API is used by
providing the timestamps as part of the command construction:
<BASE_URI>/DeviceGroupHierarchy/{HierarchyAddedOrUpdatedTimestamp}&
{HierarchyDeletedTimestamp}&{ DeviceGroupAddedOrUpdatedTimestamp}&{
DeviceGroupDeletedTimestamp}&{ DeviceToGroupAddedOrUpdatedTimestamp}&{
DeviceToGroupDeletedTimestamp}
Operations Supported : GET
For example, to get the complete device hierarchy, the following API can be used:
