# send\_raw\_transaction - Monero

This non-JSON-RPC endpoint broadcasts a serialized signed transaction to the network. It is the primary submission point for transactions constructed and signed offline by a wallet.

## Parameters

| Parameter      | Type    | Required | Description                                                                            |
| -------------- | ------- | -------- | -------------------------------------------------------------------------------------- |
| tx\_as\_hex    | string  | Yes      | Hex-encoded signed transaction blob                                                    |
| do\_not\_relay | boolean | No       | If `true`, the node will accept the tx but not propagate it (rare; useful for testing) |

## SDK Integration

{% tabs %}
{% tab title="monero-javascript" %}

```javascript
// Non-JSON-RPC HTTP endpoints are not exposed by typed SDK methods.
// Use a plain HTTP client as shown in the Request Example above.
import axios from 'axios';

const response = await axios.post('https://go.getblock.io/<ACCESS-TOKEN>/send_raw_transaction', {"tx_as_hex": "de6a3\u2026", "do_not_relay": false});
console.log(response.data);
```

{% endtab %}

{% tab title="monero-python" %}

```python
# Non-JSON-RPC HTTP endpoints are not exposed by typed SDK methods.
# Use a plain HTTP client as shown in the Request Example above.
import requests;

response = requests.post('https://go.getblock.io/<ACCESS-TOKEN>/send_raw_transaction', json={"tx_as_hex": "de6a3\u2026", "do_not_relay": false})
