用户和机器人的会话首次被创建

应用机器人订阅该事件后，如果用户首次与该机器人进行会话，将会触发该事件。首次会话是用户了解应用的重要机会，你可以在触发事件后，向用户发送操作说明、配置地址来指导用户开始使用你的应用。

前提条件

你需要先为应用配置事件订阅，才可以在触发事件时接收到事件。事件订阅介绍参见事件概述。

事件

项目	值
事件类型	p2p_chat_create
支持的应用类型	custom,isv
权限要求 订阅该事件所需的权限，开启其中任意一项权限即可订阅 开启任一权限即可	无
字段权限要求	无
推送方式	Webhook

事件订阅流程可参考：事件订阅概述，新手入门可参考：教程

订阅方式

长连接方式（推荐）：无需发布到公网地址，在本地开发环境中即可接收事件回调，且无需处理加解密逻辑。 发送至开发者服务器：需要提供服务器公网地址。
