# Flex

Available in Classic and VPC

This document describes the Flex component of the response components of a chatbot answer.

The Flex component consists of the following four basic components.

- [Flex](/docs/en/ai-application-service-chatbot-flex#Flex%EC%BB%B4%ED%8F%AC%EB%84%8C%ED%8A%B8)
- [LineFlex](/docs/en/ai-application-service-chatbot-flex#Flex%EC%BB%B4%ED%8F%AC%EB%84%8C%ED%8A%B8)
- [LineSticker](/docs/en/ai-application-service-chatbot-flex#LineSticker%EC%BB%B4%ED%8F%AC%EB%84%8C%ED%8A%B8)
- [LineWorks Sticker](/docs/en/ai-application-service-chatbot-flex#LineWorksSticker%EC%BB%B4%ED%8F%AC%EB%84%8C%ED%8A%B8)

These components allow you to set the chatbot's response to each feature in Chatbot Builder, and return the response results in JSON format.

Note

The Flex component supports all JSON object formats, and defines its own JSON specification as needed. <e.g.> [FlexMessageContainerObject](https://developers.line.biz/en/reference/messaging-api/#container)
