# Cancel a Delta Order

To cancel orders, you can use the `/cancel` endpoint provided by the API, which would remove the orders from the order book. The signature is an EIP-712 signature, built with the following structure. Both `LIMIT` and `MARKET` orders can be canceled.

<table><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>domain</td><td><pre><code>{
  "name": "Portikus",
  "version": "2.0.0",
  "chainId": &#x3C;chainId>,
  "verifyingContract": &#x3C;deltaAddress>
}
</code></pre></td></tr><tr><td>type</td><td><pre><code>{
  "OrderCancellations": [
    {
      "name": "orderIds",
      "type": "string[]",
    }
  ]
}
</code></pre></td></tr><tr><td>value</td><td><pre><code>{
  "orderIds": [&#x3C;id1>, &#x3C;id2>]
}
</code></pre></td></tr></tbody></table>
