# 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/)**

<div>
  ### 鉴权

  Dify Service API 使用 `API-Key` 进行鉴权。

  建议开发者把 `API-Key` 放在后端存储，而非分享或者放在客户端存储，以免 `API-Key` 泄露，导致财产损失。

  所有 API 请求都应在 **`Authorization`** HTTP Header 中包含您的 `API-Key`，如下所示：

  <CodeGroup title="Code">
    ```javascript
      Authorization: Bearer {API_KEY}

    ```
  </CodeGroup>
</div>

<Row>
  <Col>
