  • name - Give your new entity a Name. Note: A name must be unique within the given parent, similar to a file in a folder.
  • parentId - The ID of the parent Entity, such as a Folder or Project. This field should be excluded when creating a Project.
  • concreteType - Indicates the type of Entity to create. The value should be the entity's fully qualified class name, e.g. org.sagebionetworks.repo.model.FileEntity.
