我正在面对使用API过程和沙箱实施PayPal定期付款的麻烦。 我成功创建订阅按钮并将用户重定向到PayPal Express结帐页面。 但是，由PayPal生成的一些IPN中缺少自定义字段，我真的需要这个字段。PAYPAL IPN自定义字段丢失
这里有我而产生的订阅按钮发送请求：
METHOD=SetExpressCheckout
&VERSION=94.0
&PWD=123456
&[email protected]
&SIGNATURE=mySignature
&PAYMENTREQUEST_0_AMT=5.00
&PAYMENTREQUEST_0_PAYMENTACTION=Sale
&PAYMENTREQUEST_0_CURRENCYCODE=EUR
&RETURNURL=http%3A%2F%2Fwww.myWebSite.com?ok
&CANCELURL=http%3A%2F%2Fwww.myWebSite.com?ko
&L_BILLINGTYPE0=RecurringPayments
&L_BILLINGAGREEMENTDESCRIPTION0=test+paypal
&REQCONFIRMSHIPPING=0
&NOSHIPPING=1
&L_PAYMENTREQUEST_0_ITEMCATEGORY0=Digital
&L_PAYMENTREQUEST_0_NAME0=test+paypal
&L_PAYMENTREQUEST_0_AMT0=5.00
&L_PAYMENTREQUEST_0_QTY0=1
&PAYMENTREQUEST_0_CUSTOM=custom_var1%3Dvalue1%7Ccustom_var2%3Dvalue2
用户确认交易完成后，他回来我的网站，我需要验证信息，并建立定期PROFIL。 下面是我做的请求：
METHOD=GetExpressCheckoutDetails
&VERSION=94.0
&PWD=123456
&[email protected]
&SIGNATURE=mySignature
&TOKEN=theToken
METHOD=CreateRecurringPaymentsProfile
&VERSION=94.0
&PWD=123456

&TOKEN=theToken
&AMT=5.00
&CURRENCYCODE=EUR

&PAYMENTREQUEST_0_PAYMENTACTION=Sale
&PAYMENTREQUEST_0_AMT=5.00
&PAYMENTREQUEST_0_CURRENCYCODE=EUR
&PAYMENTREQUEST_0_NOTIFYURL=http%3A%2F%2Fwww.myWebSite.com?notify
&PAYMENTREQUEST_0_CUSTOM=custom_var1%3Dvalue1%7Ccustom_var2%3Dvalue2
这样做之后，我收到这些IPN：

正如你可以在第一IPN看到现场定制可用，但不是在第二个。 有没有人知道我在第二个IPN中检索自定义字段时缺少什么？
看到它谢谢你的提示，这将是非常有用的。 – Shaolin
