如您所见，有一个名为 rp_invoice_id 的字段，它是商家自己的唯一引用号或发票号，可用于唯一标识配置文件。 p>

创建API调用CreateRecurringPaymentsProfile时，如何传递这个值，应该在API调用中设置哪个字段？

谢谢

Answer 1

您需要使用 PROFILEREFERENCE 参数传入一个值，该值将通过 rp_invoice_id 参数中的 IPN 返回。

PROFILEREFERENCE

(Optional) The merchant's own unique reference or invoice number.

Character length and limitations: 127 single-byte alphanumeric characters
