# raknet.send

Sends a packet of your own onto the network, as if the client sent it.

```luau theme={null}
raknet.send(data: buffer | string | {number}, priority: number, reliability: number, orderingChannel: number): ()
```

RakNet is the network connection between your client and the Roblox server over the internet. <br />Pretty much the same as `RemoteEvent`s and `RemoteFunction`s - they send their data the same way. This function just builds the packet yourself instead of going through a remote.

`data` is the payload, in any of the same three forms a `RakNetMessage` exposes. `priority`, `reliability`, and `orderingChannel` are RakNet's standard send numbers; copy them from the packet you are replaying instead of guessing.

## Parameters

| Parameter         | Type                           | Description                                |
| ----------------- | ------------------------------ | ------------------------------------------ |
| `data`            | `buffer \| string \| {number}` | The packet payload.                        |
| `priority`        | `number`                       | RakNet send priority.                      |
| `reliability`     | `number`                       | RakNet reliability mode.                   |
| `orderingChannel` | `number`                       | Ordering channel used for ordered traffic. |

<Tip>
  Lower-level protocol sending can easily trigger server bans if incorrect values are sent.
