第三方平台不能给授权方增加平台有的订阅消息模板，之前旧的 模板消息-->组合模板并添加到个人模板库 是可以的
这个增加订阅的接口：https://api.weixin.qq.com/wxaapi/newtmpl/addtemplate
{"tid":"1162","kidList":["2","1","5","4","3"],"sceneDesc":"新订单通知"}
返回
{"errmsg":"tid does not exist","count":0,"data":[],"errcode":200014}
tid是第三方的模板id
不能引用平台的订阅模板消息了
tid填写的是242？可以检查一下模板标题ID看看：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/Mini_Programs/subscribe_template/add_template.html
{"tid":"814","kidList":["4","6","1","9","5"],"sceneDesc":"订单退款通知测试"}
