    [next_payment_date] => 03:00:00 Jun 21, 2012 PDT
    [protection_eligibility] => Ineligible
    [payment_cycle] => Weekly
    [tax] => 0.00
    [payer_id] => K48P3Fxxxx
    [payment_date] => 16:52:28 Jun 14, 2012 PDT
    [payment_status] => Completed
    [product_name] => Virtual Subscription &#36;6.56 / week for 3 weeks
    [charset] => windows-1252
    [rp_invoice_id] => 208
    [recurring_payment_id] => I-4DHKxxxx
    [first_name] => Test
    [mc_fee] => 0.38
    [notify_version] => 3.4

    [profile_status] => Active
    [amount] => 6.56
    [txn_id] => 3PE0612xxxx
    [payment_type] => instant
    [last_name] => User
    [receiver_email] => xxxx@gmail.com
    [payment_fee] => 0.38
    [receiver_id] => TYDEKWLxxxx
    [txn_type] => recurring_payment
    [mc_currency] => USD
    [residence_country] => US

    [time_created] => 23:48:22 Jun 13, 2012 PDT
    [ipn_track_id] => b2c853ddxxxx

如您所见，有一个名为rp_invoice_id的字段是商家自己的唯一参考号或发票号，可用于唯一标识个人资料。

创建API调用CreateRecurringPaymentsProfile时，如何传递此值，我应该在API调用中设置哪个字段？

谢谢

Answer 1

您需要使用PROFILEREFERENCE参数传入将在rp_invoice_id参数中通过IPN返回的值。

PROFILEREFERENCE

（可选）商家自己的唯一参考号或发票号。

Answer 2

它不会像这样工作，新版本的API正在使用REST调用。

要使其正常工作，您必须先下载Paypal SDK。它位于http://paypal.github.io/sdk/

确保使用SDK的官方版本，可能有可能使用不同的版本，有人可能会坐在那里窃取您的宝贵信息。我的建议是在开始工作之前通过原始文档，有一个想法。

安装SDK后，您可以使用下面链接中给出的示例

https://devtools-paypal.com/guide/recurring_payment_cc/php?interactive=ON&env=sandbox

这将进行API调用。

您也可以尝试使用https://developer.paypal.com/webapps/developer/docs/api/
