# Cancel Multiple Orders

`POST /v1/orders/batched/cancel`

Cancel up to 20 orders in a single request. If any entry fails request-shape validation, the whole batch is rejected by the gateway before reaching the exchange. The exchange may silently ignore unknown `orderId`s. `canceledOrderIds` is an echo of the request, not a confirmation; observe actual outcomes on the order stream.

## Request body

- CancelOrderListRequest
  - `requests` CancelOrderRequest[]
    - `orderId` string
    - `clordId` string
    - `symbol` string

## Response `200`

All orders successfully submitted for cancellation

- CancelOrderListResponse
  - `responses` CancelOrderResponse[]

## Other responses

- `400` — Bad request - invalid batched cancel request or exceeds max batch size
- `401` — Unauthorized - invalid or missing authentication token
- `500` — Internal server error
