Paypal 自适应付款发票数据

Question

我正在尝试添加项目详细信息以显示在 Paypal 发票上，但没有显示任何内容。我使用具有以下值的 SetPaymentOptions:

"payKey" => "$payKey",
"receiverOptions(0).customId" => "11",
"receiverOptions(0).receiver.email" => "email@paypal.com",
"receiverOptions(0).description" => "Invoice Title",
"receiverOptions(0).invoiceData.item(0).name" => "Item name",
"receiverOptions(0).invoiceData.item(0).itemCount" => "1.0",
"receiverOptions(0).invoiceData.item(0).itemPrice" => "20.0",
"receiverOptions(0).invoiceData.item(0).price" => "20.0",
"receiverOptions(0).invoiceData.item(0).identifier" => "111",
"receiverOptions(0).invoiceData.totalTax" => "0.0",
"requestEnvelope.errorLanguage" => "en_US",
"requestEnvelope.detailLevel" => "ReturnAll"

代码是用 PHP 编写的，我使用的是嵌入式支付。有没有人知道为什么除了 paykey 请求中传递的信息外，发票上没有显示任何详细信息？谢谢...

Answer 1

itemCount 应该是一个整数:

"receiverOptions(0).invoiceData.item(0).itemCount" => "1",

通过该更改(和有效的 receiver.email)，SetPaymentOptions 调用成功。
