# 创建端点应用示例
#### 概述
本文指导用户通过调用API的方式，介绍创建端点的完整流程，包括创建端点、查看端点流程。
本流程假设终端租户已经在Console界面完成AI DataLake的服务授权，且已创建工作空间。API的调用方法请参见[如何调用API](https://support.huaweicloud.com/api-aidatalake/aidatalake_02_0004.html)。
#### 前提条件
- 已完成AI DataLake服务授权。
- 已获取待创建资源池的工作空间ID。
- 如果创建预留资源和混合模式的端点，还需要计算资源池ID，如果是按需弹性的端点，则不需要计算资源池ID。
 
#### 创建端点
- 接口相关信息 URI格式：POST /v2/workspaces/{workspace_id}/endpoints
  {workspace_id}：为端点所在工作空间ID。
  详情请参见[创建端点 - CreateV2Endpoint](https://support.huaweicloud.com/api-aidatalake/CreateV2Endpoint.html)。
  
- 请求示例 POST /v2/workspaces/{workspace_id}/endpoints

#### 查看端点详情
- 接口相关信息 URI格式：GET /v2/workspaces/{workspace_id}/endpoints/{endpoint_id}
  {workspace_id}：资源池所在工作空间ID。
  详情请参见[查询端点详情 - ShowV2Endpoint](https://support.huaweicloud.com/api-aidatalake/ShowV2Endpoint.html)。
  
- 请求示例 GET /v2/workspaces/{workspace_id}/endpoints/{endpoint_id}
