檢測paypal訂閱取消登錄asp.net

Question

我正在構建一個涉及paypal訂閱的asp.net web應用程序。我需要檢查用戶是否已經取消登錄是可能的，如果是的話如何？我已經看到關於這個主題的其他帖子，但我的情況是不同的，因爲我會檢查登錄。我在想，也許我可以每晚從PayPal批量轉儲數據，並檢查這些數據，以便爲取消的用戶設置標誌。不知道這是做什麼最好的辦法..

Answer 1

如果你想檢查用戶登錄到貝寶後是否接受或取消協議，那麼是的，你可以通過使用快速結賬令牌來檢查這一點。您需要在買方登錄PayPal賬戶並在響應中查找變量BILLINGAGREEMENTACCEPTEDSTATUS後，在令牌上的API上調用GetExpressCheckoutDetails。

BILLINGAGREEMENTACCEPTEDSTATUS = 0意味着買方不接受該協議或點擊登錄到支付寶賬戶後取消。

BILLINGAGREEMENTACCEPTEDSTATUS = 1，表示在登錄到PayPal後點擊「同意並繼續」。

我已經包含了一些示例響應。
