Telegram bots can interact with chats and users through a webhook system that enables it to be updated about chats changes, new commands and user interactions without continuously polling Telegram APIs for updates.

## Default Handler

A default "do nothing" handler is shipped with Telegraph installation, it can only handle a single chat command:

```
/chatid
```

And answers with the ID of the chat the command is issued into. It is useful to get the ChatID in order to register a new chat in Telegraph


## Custom Handler

In order to write custom webhook and commands handlers the default handler must be switched with a custom one

```php
// app/Http/Webhooks/MyWebhookHandler.php

class MyWebhookHandler extends \DefStudio\Telegraph\Handlers\WebhookHandler
{
    public function myCustomHandler(): void
    {
        // ... My awesome code
    }
}
```

<alert type="alert">A custom webhook handler must extend `DefStudio\Telegraph\Handlers\WebhookHandler` and has to be registered in `config('telegraph.webhook_handler')`</alert>
