问题描述

我正在我的网站上应用贝宝结帐流程.我想在成功付款后更新数据库.我给出了正确的notify_url，但是这个URL从未被调用过，但是我已经在Sandbox Paypal中成功付款了.我放置了一个电子邮件地址，以检查是否调用了功能upadatePayments()，但是在贝宝响应后没有收到邮件.

I am applying a paypal checkout process in my website.In which i want to update database after the successful payment.I have given the correct notify_url but this url never been called but i have reached at a successful payment in Sandbox Paypal.I have put a email address to check whether the function upadatePayments() is called or not but getting no mail after the paypal response.

我正在使用的代码如下:-

The code i am using is below:-

index.html

index.html

<form class="paypal" action="payments.php" method="post" id="paypal_form" target="_blank">

推荐答案

您必须登录[email protected]帐户(在www.sandbox.paypal.com下)，转到帐户设置，个人资料，即时付款通知设置

You have to log into the [email protected] account (under www.sandbox.paypal.com),Go to the account settings, profile , instant payment notification settings

(https://www.sandbox.paypal.com/us/cgi-bin/webscr?cmd=_profile-ipn-notify)

(https://www.sandbox.paypal.com/us/cgi-bin/webscr?cmd=_profile-ipn-notify)

并确保已启用此功能.

PayPal在反复失败后会自动将其关闭，无论您是否在API调用中指定了该IPN，都将禁用该帐户的所有 IPN.

PayPal automatically turns it off after repeated failures, and that disables all IPN's for the account, regardless of whether you specified it in the API call.
