PayPal Webhooks：发票，付款销售，授权和捕获Webhooks需要，如果我只使用计费协议

Question

我需要涵盖的商业模式是只出售订阅。我不需要出售单独的产品。我的问题是：我是否需要实施和支持收听发票，付款销售，授权和捕获webhooks，或者我可以只实施帐单计划和订阅webhooks？

发票和付款网络挂接这我指的是：

Payment authorization created 
Payment authorization voided 
Payment capture completed 
Payment capture denied 
Payment capture pending 
Payment capture refunded 
Payment capture reversed 
Payment sale completed 
Payment sale denied 
Payment sale pending 
Payment sale refunded 
Payment sale reversed 
Invoicing invoice cancelled 
Invoicing invoice paid 
Invoicing invoice refunded 

Answer 1

如果不处理模型中的任何款项，你只关心订阅，您可以单独实现订阅网络挂接。但是，如果您处理任何付款，我们建议您实施并收听付款相关的Webhook，以便通知您。

谢谢！
