# 创建、更新、查询及删除会议室

> 完整演示通过企业内部应用调用智能会议室 API 完成会议室创建、更新、查询和删除的接入流程，包含获取应用凭证与添加接口权限两个关键步骤。

本文档展示了，创建一个企业内部应用，使用智能会议室提供的API，实现会议室的创建、更新、查询和删除操作的相关流程。

## 预期效果

会议室展示效果如下：

![预期效果](https://help-static-aliyun-doc.aliyuncs.com/assets/img/zh-CN/2017088771/p524058.png)

## 流程简介

前提条件：完成[应用创建与配置](/zh/open/dingstart/create-application)的流程。

步骤一：获取应用凭证信息，获取应用 Client ID 和 Client Secret。

步骤二：申请接口权限，申请智能会议室相关接口权限。

步骤三：获取应用访问凭证[获取企业内部应用的accessToken](/zh/open/development/obtain-the-access-token-of-an-internal-app)。调用接口时，通过accessToken鉴权调用者身份。

步骤四：调用会议室相关API：

1. 调用服务端API-[创建会议室](/zh/open/development/create-a-meeting-room)接口，获取会议室返回结果`result`字段\*\*，**即会议室ID**。\*\*
2. 根据会议室ID，调用服务端API-[更新会议室信息](/zh/open/development/update-meeting-room-information)接口，实现会议室信息更新操作。
3. 调用服务端API-[查询会议室列表](/zh/open/development/check-the-meeting-room-list)接口，实现获取会议室列表内容。
4. 根据会议室ID，调用服务端API-[查询会议室详情](/zh/open/development/check-meeting-room-details)接口，实现获取单个会议室具体内容信息。
5. 根据会议室ID，调用服务端API-[删除会议室](/zh/open/development/delete-a-meeting-room)接口，实现删除会议室操作。

## 前提条件

完成[应用创建与配置](/zh/open/dingstart/create-application)的流程。

## 步骤一：获取应用凭证

1. 选择目标应用，进入应用详情页，单击**基础信息** > **凭证与基础信息**。
2. 获取应用 Client ID 和 Client Secret。

## **步骤二**：添加接口权限

单击**开发配置** > **权限管理**，在权限搜索框中分别输入`VideoConference.Conference.Write`和`VideoConference.Conference.Read`，并申请权限。

## **步骤三**：获取应用访问凭证accessToken

<Warning>
  服务端API差异详情参见旧版API VS 新版API。以下接口均使用服务端API接口，SDK下载详情参见服务端SDK下载。
</Warning>

根据步骤一中的 Client ID 和 Client Secret，获取应用访问凭证[获取企业内部应用的accessToken](/zh/open/development/obtain-the-access-token-of-an-internal-app)。

```java theme={"theme":{"light":"github-light","dark":"github-dark"}}
 public void getAccessToken() throws Exception {
        Config config = new Config();
        config.protocol = "https";
        config.regionId = "central";
        com.aliyun.dingtalkoauth2_1_0.Client client = new com.aliyun.dingtalkoauth2_1_0.Client(config);
        GetAccessTokenRequest accessTokenRequest = new GetAccessTokenRequest()
                .setAppKey("din*********hgn")
                .setAppSecret("9G_O************mBkhgGIO");
        GetAccessTokenResponse accessToken = client.getAccessToken(accessTokenRequest);
        System.out.println(JSON.toJSONString(accessToken.getBody()));
    }
```

## **步骤四**：调用会议室相关API

1. 调用服务端API-[创建会议室](/zh/open/development/create-a-meeting-room)接口，获取会议室返回结果`result`字段\*\*，**即会议室ID**。\*\*
