# Bulk Cancel

**POST /auth/cancel/bulk**

Cancel orders in bulk. This endpoint is recommended when you need to cancel more than 5 orders at once.

By using this endpoint you will only consume a single rate limit request and not 5. It will also be much faster than cancelling the orders individually.

Requires a signed payload in HMAC-SHA256 form to be appended to the x-signature header. The signed payload must be base64-encoded.

Javascript example:

  ```
  const formurlencoded = require('form-urlencoded').default;
  const crypto = require("crypto-js");
  const fetch = require("node-fetch");
  const API_KEY = "<YOUR_API_KEY>";
  const SECRET_KEY = "<YOUR_SECRET_KEY>";

  (async function() {
    const payload = {'ids': ['392392320eoweqwie3', '482392320eoweqwii5']};
    const payload_url_encoded = formurlencoded(payload);
    const HMAC = crypto.HmacSHA256(payload_url_encoded, SECRET_KEY).toString(crypto.enc.Base64);
    const submitted = await fetch('https://api.testnet.everstrike.io/auth/cancel/bulk', {method: 'POST', body: payload_url_encoded, headers: {'content-type': 'application/x-www-form-urlencoded', 'x-api-key': API_KEY, 'x-signature': HMAC}});
    const response = await submitted.json();
    console.log(response);
  })();
  ```
