PATCH/api/v1/datasets/{datasetId}/cases

Bulk-assign or clear a named split on dataset cases

Sets (or clears, when split=null) the named partition of the given cases within a dataset. Pinned to the dataset so stray caseIds from other datasets are no-ops. Caller must be an editor on the dataset's project org.
