paypal - 将 CUSTOM 变量发送到 CreateRecurringPaymentsProfile

Question

我正在实现定期快速结账。创建配置文件的代码正在运行。我现在要做的是将自定义值传递给它。

我们可以通过

DoExpressCheckout

和

SetExpressCheckout

使用以下名称

PAYMENTREQUEST_n_CUSTOM

我想对 CreateRecurringPaymentsProfile 做同样的事情以便我可以在 IPN 中访问它。

Answer 1

CRPP 不像其他 API 请求那样包含自定义参数，但是它包含 PROFILEREFERENCE 参数，该参数将被视为发票 ID。您在此处传递的任何值都会作为 rp_invoice_id 在 IPN 中返回。

因此，您可以做的是在您的数据库中保存本地发票记录，其中包含您需要的任何相关数据，然后在 CRPP 请求的 profilereference 参数中传递该 ID。然后在您的 IPN 脚本中，您从 rp_invoice_id 中提取该值，然后使用该 ID 值从您的数据库中提取您需要的关于该发票的任何额外详细信息。

这是一个包含 rp_invoice_id 的 IPN 示例。
