title: Resource Pack Push
description: "Configuration 0x09, server → client."
---

`config` · `0x09` · **clientbound** (server → client)

Asks the client to download and apply a resource pack: `uuid`, URL, SHA-1 hash, `forced` flag, and an optional prompt message. The client reports progress with `ResourcePack` (serverbound). If forced and the player declines, the client disconnects.

Sent by the server, read by the client. Listen for it with `client.on("ResourcePackPush", (data) => …)` on the receiving side.

## Fields

| Field | Type | Notes |
|---|---|---|
| `uuid` | UUID |  |
| `url` | String |  |
| `hash` | String |  |
| `forced` | Boolean |  |
| `promptMessage` | Optional |  |

## Send it

```ts
await client.sendPacket("ResourcePackPush", {
  uuid: "12345678123456781234567812345678",
  url: "https://cdn.example.com/server-pack.zip",
  hash: "0123456789abcdef0123456789abcdef01234567", // SHA-1
  forced: false,
  promptMessage: { text: "Install the server resource pack?" },
});
```

Use a stable 32-hex-character UUID to identify the pack and its 40-character SHA-1 in `hash`. Set `promptMessage` to `null` to omit the custom prompt. The client reports progress with serverbound `ResourcePack` packets.

Field aliases listed under Notes are accepted as alternative keys when writing.
