# Build a Headless Experience

Agentforce SDK also supports a headless experience for Agentic Use Cases that do not require a chat style interaction. The headless experience can also be used to build your own UI entirely.

## Send Messages

To send a message to the agent, you can use the sendUtterance method on the AgentConversation object.

```swift
await conversation.sendUtterance(utterance: "Hello, world!", attachment: nil)
```

## Receive Messages

To receive messages from the agent, you can subscribe to the messages publisher on the AgentConversation object.

```swift
conversation.messages
    .sink { messages in
        // Handle new messages
        for message in messages {
            print(message.message)
        }
    }
    .store(in: &cancellables)
```

A message is an instance of an AgentforceMessage which includes a message property containing the primary text response from the agent and components which may contain rich UI component definitions for the response.
