推荐答案
您必须登录akaash_1351258109_biz@gmail.com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 akaash_1351258109_biz@gmail.com 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.
