我正面临着使用API流程和沙箱实现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快速结账页面.但是在paypal生成的某些IPN中缺少自定义字段,我真的需要这个字段.
以下是我在生成订阅按钮时发送的请求:
METHOD=SetExpressCheckout
&VERSION=94.0
&PWD=123456
&USER=myEmail@biz.com
&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

&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
用户确认交易后,他将返回我的网站,我必须验证信息并创建重复的配置文件.以下是我的要求:
METHOD=GetExpressCheckoutDetails
&VERSION=94.0
&PWD=123456
&USER=myEmail@biz.com
