You can customize the chat messages you send and receive by importing the ZEPETO.Chat package.

:::hint{type="danger"}
❗️ **Caution**

- This feature is available in a World where multiplayer elements are implemented.
:::

:::hint{type="success"}
👍 **Points for reference**

- You can send/receive chat even in an editor environment.
- Only chat messages created by users through handlers can be sent/received (quick chat, system messages cannot be received)
:::



## Function definition

```typescript
class ZepetoChat extends System.Object {
    public static get Instance(): ZepetoChatImplementation;
    public static get OnReceivedMessage(): UnityEngine_Events.UnityEvent$1<IMessage>;
    public constructor();
    public static Send($message: string): void;
}
```

- ZepetoChat.You can use Send() to send specific messages to the chat window.
- You can use the ZepetoChat.OnReceivedMessage.AddListener() to determine which event to receive the message.



## Example of use

Create a custom message in inputField to send the message.
