# Replies / Notifications

## Usage

### **On-demand**

```ruby
user = User.first
user.notification.text "Hello!"
user.notification.typing 1.second
user.notification.text("How are you today?")
user.notification.send()
```

### As Reply in the Conversation

Using the <mark style="color:blue;">`@reply`</mark> instance, accessible from any [action block](https://docs.kogno.io/contexts/blocks) in a context or in the callbacks from the [`Conversation`](https://docs.kogno.io/conversation) class.

```ruby
class MainContext < Conversation

  def blocks

    intent "greeting" do
    
      @reply.text "Hello!"
      @reply.typing_on(2)
      @reply.quick_reply(
        "How are you today?",
        [
          {
            title: "I'm good",
            payload: :good
          },
          {
            title: "Had better days",
            payload: :bad
          }
        ]
      )
      
    end
  
  end

end
```

{% hint style="info" %}
For this case, the call to the `send()` method is not necessary, since i&#x74;*'s* a reply within the conversation, therefore the framework will do it automatically.
{% endhint %}

## Notification Formats

{% hint style="success" %}
In Kogno, we try to **unify** as many formats as possible, in order to allow developers to write a unified code for a **cross-platform** conversational application.
