# consensus\_unsubscribe - Tempo

Example code for the consensus\_unsubscribe JSON-RPC method. Complete guide on how to use consensus\_unsubscribe JSON-RPC in GetBlock Web3 documentation.

{% hint style="warning" %}
**VALIDATOR-NODE-ONLY METHOD.** This method is part of the `consensus_*` namespace and is only available on Tempo validator nodes. It is **not** available on shared RPC infrastructure such as GetBlock's standard shared endpoints. Calling this method against a non-validator node returns `-32601 Method not found`. If you need access, contact GetBlock about dedicated validator-node access.
{% endhint %}

Cancels an existing consensus subscription created with `consensus_subscribe`. WebSocket-only and validator-only.

## Parameters

| Parameter      | Type   | Required | Description                                       |
| -------------- | ------ | -------- | ------------------------------------------------- |
| subscriptionId | string | Yes      | Subscription ID returned by `consensus_subscribe` |

## Request Example

{% tab title="cURL" %}

```bash
# WebSocket-only method. Use wscat (or similar) to connect first:
wscat -c 'wss://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/'

# Then send:
{"jsonrpc": "2.0", "method": "consensus_unsubscribe", "params": ["0x9cef478923ff08bf67fde6c64013158d"], "id": "getblock.io"}
```

{% endtab %}

{% tab title="JavaScript (Axios)" %}

```javascript
import WebSocket from 'ws';

const ws = new WebSocket('wss://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/');

ws.on('open', () => {
    ws.send(JSON.stringify({
    "jsonrpc": "2.0",
    "method": "consensus_unsubscribe",
    "params": [
        "0x9cef478923ff08bf67fde6c64013158d"
    ],
    "id": "getblock.io"
