你好，绑定开发小程序和授权是两个不同的操作。基本概念参考：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/getting_started/terminology_introduce.html#_2%E3%80%81%E2%80%9C%E7%BB%91%E5%AE%9A%E2%80%9D-VS-%E2%80%9C%E6%8E%88%E6%9D%83%E2%80%9D

1、了解下绑定开发小程序基本概念：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/operation/thirdparty/dev.html

开发小程序指的是服务商用于开发用途的小程序账号，该账号通常不会发布上线，仅仅用于登录微信开发者工具进行代码编写&提交。

服务商可以专门定义一个小程序为开发小程序用于进行代码编写&提交。

2、授权参考：

第三方平台开发者构建授权链接：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/Before_Develop/Authorization_Process_Technical_Description.html

商家授权：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/operation/authorization/authorization_management.html#%E4%BA%8C%E3%80%81%E5%95%86%E5%AE%B6%E7%9A%84%E6%93%8D%E4%BD%9C

接收授权通知：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/Before_Develop/authorize_event.html

代开发小程序可以理解成第三方平台的开发模版，和授权小程序不是一个东西，关于授权的可以看一下文档
