# Slack Message

UI Bakery allows you to send Slack messages from your action to a predefined channel webhook.

By default, you can send plain text messages like this:

```javascript
{
  text: 'Hello World!'
}
```

Slack API returns the `"ok"` string if the message was sent successfully.

In addition to sending text messages, you can also reference the data from the previous step or the data of the UI component:

```javascript
{
  text: 'Hello ' + {{data.name}} + '!'
}
```

```javascript
{
  text: 'Hello ' + {{ui.input.value}} + '!',
}
```

***

You can also use Slack's [extended message formatting options](https://api.slack.com/messaging/webhooks#advanced_message_formatting), such as block & attachments.
