What this endpoint does

Permanently removes up to 100 cases in a single request by their TaskIdentity IDs (formatted as task:<UUID>, obtainable from the Case Search endpoint). The operation handles partial success gracefully — if some IDs refer to already-deleted or non-existent cases, those are reported separately rather than causing an error. The request body is a JSON array of TaskIdentity strings. For deleting a single case by path parameter, use the Delete endpoint instead.

Response data

Returns a deleted array listing TaskIdentity strings for cases that were actually removed, and an ignored array for IDs that were skipped (already deleted or non-existent). The status message provides a human-readable summary of the outcome, such as "Successfully deleted 2 Cases. 1 Case already deleted." This split allows callers to distinguish real deletions from no-ops and confirm the operation's full effect.
