Only users with the ADMINISTRATOR scope in the current context can delete hierarchy levels. Make sure your API token grants administrator privileges. See Understanding Scopes for more information.
To delete a hierarchy level, use the deleteHierarchyLevel mutation.
Important: this operation is irreversible. After deletion, the hierarchy level is removed and will no longer appear in the hierarchy tree or any assignments where it was used.
Access policy:
  • The API user context must have permission to manage hierarchy levels.
  • A hierarchy level with the given id must exist.
The mutation accepts the following argument:

idIDRequired. The ID of the hierarchy level to delete.—

    id: "23"
