PayPal Webhooks：發票，付款銷售，授權和捕獲Webhooks需要，如果我只使用計費協議

Question

我需要涵蓋的商業模式是隻出售訂閱。我不需要出售單獨的產品。我的問題是：我是否需要實施和支持收聽發票，付款銷售，授權和捕獲webhooks，或者我可以只實施帳單計劃和訂閱webhooks？

發票和付款網絡掛接這我指的是：

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

如果不處理模型中的任何款項，你只關心訂閱，您可以單獨實現訂閱網絡掛接。但是，如果您處理任何付款，我們建議您實施並收聽付款相關的Webhook，以便通知您。

謝謝！
