What this endpoint does

Modifies one or more properties of an existing case identified by its TaskIdentity ID (formatted as task:<UUID>, obtainable from the Case Search endpoint). At least one field besides the ID must be specified — providing only the ID returns an error. Only the fields included in the request are changed; omitted fields remain unchanged. Each update is recorded as a tracked change in the case's activity log, visible through the Lookup Many endpoint's log panel. To unassign a case, pass an empty string for the assignee field.

Response data

Returns a status object confirming the update was applied. The response does not echo the updated case data — use the Lookup Many endpoint with the case ID to verify the changes took effect and to see the corresponding log entry recording what was modified.
