Looking for a suggestion on how to achieve the following from using the Content Delivery API. I want to query the API to get the tree structure of my nodes. Specifically I want to pick a single node and get all of its children (doable) and grandchildren (not doable without doing multiple requests). But generally it would suffice to get all nodes in a nested/structured manner. I can ask for ALL nodes but they are returned "flat". Or I can ask for directly descending children but only for a single nested level. Is this possible somehow?
