# 对话型应用 API

可用于大部分场景的对话型应用，采用一问一答模式与用户持续对话。要开始一个对话请调用 chat-messages 接口，通过继续传入返回的 conversation_id 可持续保持该会话。**[开始前请阅读 !! 什么是 Bearer Token ？](https://swagger.io/docs/specification/authentication/bearer-authentication/)**

<Heading

  method='POST'
  title='发送对话消息'
  name='#Create-Chat-Message'
/>
<Row>
  <Col>
    创建会话消息，或基于此前的对话继续发送消息。
