PUT /account/cancel-on-disconnect

Set cancel-on-disconnect

Set cancel-on-disconnect.

operationId: setCancelOnDisconnect

Not reachable through CCXT. Cancel-on-disconnect is a Nexus session policy, not a CCXT method.

Authentication: hmacAuth.

Enables or disables cancel-on-disconnect for the authenticated account. Opt-in is per account and off by default: someone who deliberately leaves a passive resting order while offline should not have a brief blip cancel it. Enable it when you want the guarantee that a dead client cannot keep orders resting — typical for market makers and algorithmic traders. Returns the resulting COD status (same shape as the GET).

Request body

Required. SetCancelOnDisconnectRequest — application/json.

{
  "enabled": true
}

Responses

Status	Body	Meaning
200	CancelOnDisconnectStatus	The resulting cancel-on-disconnect status for the account.
400	— (no schema declared)	Malformed request body.

  -H 'X-API-Key: nx_7f3a1b...' \
  -H 'X-Timestamp: 1776033911836' \
  -H 'X-Signature: <hmac-sha256>' \

Python

import requests

headers = {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>",
    "Content-Type": "application/json"
}
payload = {
    "enabled": true
}

response = requests.put("https://exchange.nexus.xyz/api/exchange/account/cancel-on-disconnect", headers=headers, json=payload)
response.raise_for_status()
print(response.json())

TypeScript

const response = await fetch("https://exchange.nexus.xyz/api/exchange/account/cancel-on-disconnect", {
  method: "PUT",
  headers: {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    "enabled": true
  }),
});
if (!response.ok) throw new Error(`${response.status} ${await response.text()}`);
console.log(await response.json());

X-Signature is a placeholder: it is derived from this specific request. See Authentication for the canonical string and the HMAC rule.
