Create a dataset group in a workspace. PromptLayer also creates an initial draft dataset for the group with version_number = -1.

​
Behavior Notes

  • Dataset group names must be unique within a workspace.
  • If folder_id is omitted, the dataset group is created at the workspace root.
  • Use Resolve Folder ID by Path to look up a folder ID, or Create Folder to create one.
