# Cancel

**POST /auth/cancel**

Cancel an order. 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:

  ```js
  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 = {'id': '392392320eoweqwie3'};
    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', {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);
  })();
  ```

Python example (Python3):

  ```python
  import requests
  import urllib
  import hmac
  import hashlib
  import base64
  from time import time

  api_key = '<YOUR_API_KEY>'
  secret_key = '<YOUR_SECRET_KEY>'
  url='https://api.testnet.everstrike.io/auth/cancel'
  payload = {'id': '32302131320dqe'}
  urlencoded_payload = urllib.parse.urlencode(payload)
  hmac_signature = hmac.new(bytes(secret_key , 'utf-8'), msg = bytes(urlencoded_payload , 'utf-8'), digestmod = hashlib.sha256).digest()
  hmac_signature_base64 = base64.b64encode(hmac_signature)
  headers = {'content-type': 'application/x-www-form-urlencoded', 'x-api-key': api_key, 'x-signature': hmac_signature_base64}

  response = requests.post(url, data=payload, headers=headers)

  print(response.text)
  print(response.status_code, response.reason)

  ```
