我是新來的developer.paypal.com,我在www.sandbox.paypal.com創建了一個訂閱按鈕,是否可以將支付的金額客戶向我的網站訂閱或者在www.sandbox.paypal.com上發佈的詳細信息?如果是這樣,您能向我展示一些關於如何做到這一點的例子。是否有可能將金額返還給我的網站
我嘗試訂閱按鈕後,這是返回的價值,我找不到一些價值的鏈接,你提供或訂閱變量我怎麼能顯示它們?
我無法獲得我的訂閱的開始日期和結束日期 謝謝。

您可以通過以下兩種方法之一來完成這一操作。付款完成後,您可以使用IPN或PDT將信息返回到您的網站。兩種方式中更好的方法是使用IPN,或至少將IPN與PDT結合使用。
Instant Payment Notification (IPN)是一種消息服務,通知您與PayPal交易相關的事件。您可以使用它來自動執行後臺和管理功能,例如履行訂單,跟蹤客戶以及提供與交易相關的狀態和其他信息。
你可以找到更多關於IPN頁here。同樣在該頁面的左邊是一些更有用的鏈接。有用於創建監聽器,設置,測試,IPN歷史記錄,IPF與FMF,IPN/PDT變量以及示例代碼here的頁面。還有一些sample code here的例子。
PayPal’s PDT系統向使用PayPal付款標準的商家網站發送訂單確認,並讓他們驗證此信息。然後這些站點可以在「訂單確認」頁面中本地顯示這些數據。 IPN比PDT更可靠,並且PDT也依賴於買家點擊一個按鈕返回到您的網站。如果他們沒有點擊按鈕返回到您的網站,則不會發回任何信息,您也不能像IPN那樣重新發送此信息。您可以在PDT here上找到更多信息。
我個人只在我的網站上使用PDT來創建一個動態感謝頁面,並使用IPN更新我的數據庫並自動完成一些任務。希望這可以幫助。 :)

您可以通過測試付款並查看腳本是否符合要求,或者使用開發者帳戶中的IPN模擬器發送測試IPN POST。 – 2013-05-02 17:50:12
您將無法使用IPN URL的本地主機地址。請記住,IPN是在幕後發送的,因此當PayPal服務器發送出去時,它會將它發送到該服務器上的本地主機,而不是您的本地主機。 – 2013-05-02 18:33:08
