# Cancel batch of orders by order IDs

DELETE https://api.prod.paradex.trade/v1/orders/batch
Content-Type: application/json

Queues cancellation for multiple orders by providing identifiers in a batch.

The request body can contain either or both of:

* `order_ids`: Array of order IDs assigned by Paradex
* `client_order_ids`: Array of client-assigned order IDs

```json
{
  "order_ids": ["order-id-1", "order-id-2"],
  "client_order_ids": ["client-id-1", "client-id-2"]
}
```

Returns a 200 OK status code with detailed results for each order:

```json
{
  "results": [
    {
      "id": "order-id-1",
      "client_id": "client-id-X",
      "account": "account-1",
      "market": "BTC-USD-PERP",
      "status": "QUEUED_FOR_CANCELLATION"
    },
    {
      "id": "order-id-2",
      "client_id": "client-id-Y",
      "account": "account-1",
      "market": "ETH-USD-PERP",
      "status": "ALREADY_CLOSED"
    },
    {
      "id": "order-id-3",
      "client_id": "client-id-1",
      "account": "account-1",
      "market": "BTC-USD-PERP",
      "status": "QUEUED_FOR_CANCELLATION"
    },
    {
      "client_id": "client-id-2",
      "status": "NOT_FOUND"
    }
  ]
}
```

Each result includes:

* `id`: Order ID (if the order was found)
* `client_id`: Client order ID (if available)
* `account`: Account that owns the order
* `market`: Market of the order
* `status`: One of:
  * `QUEUED_FOR_CANCELLATION`: Order was successfully queued for cancellation
  * `ALREADY_CLOSED`: Order was already in a closed state
  * `NOT_FOUND`: The order with the provided ID/client ID was not found

Confirmation of cancellation will be sent via websocket or can be verified from
GET /orders/:id endpoint.

Orders that are already in a CLOSED state will be included in the response with
status "ALREADY\_CLOSED".
