title: Custom Click Action
description: "Play 0x44, client → server."

`play` · `0x44` · **serverbound** (client → server)

Sent when the player clicks a text component or dialog control with a `custom` click action while in play. It carries the action id and an optional NBT payload. The server handles it in its own way; vanilla only exposes it to plugins and datapack dialogs.

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

## Fields

| Field | Type | Notes |
|---|---|---|
| `id` | String |  |
| `nbt` | Byte[] |  |

## Send it

```ts
await client.sendPacket("CustomClickAction", {
  id: /* String */,
  nbt: /* Byte[] */,
});
```

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