PayPal 自适应支付 API - 延迟链支付(PHP、JavaScript)

Question

在我的服务器端，我刚刚开始通过 AngelEye PHP SDK 收到自适应支付 API 的积极响应，以实现延迟链式支​​付，主要收款人持有资金长达 90 天，分散到次要收款人帐户。

在客户端，我使用我的 JSON 编码 API 响应返回的 RedirectURL 将用户重定向到结帐。所以最坏的情况已经过去，但我不明白 PayPal 所说的“明确地向次级收款人付款”是什么意思？

是否明确暗示我必须登录到我的 PayPal 并在他们满足我设置的条件后手动将资金支付到辅助接收方账户？首先，我想弄清楚如何在延迟链式支​​付中延迟链。一旦我(应用程序所有者)从辅助接收方(例如跟踪号码)接收到条件，我能否让资金以某种方式自动发送到我的服务器上

延迟链式支​​付

By default, payments to all receivers in a chained payment are immediate. 
However, you can choose to delay a payment to a secondary receiver. For 
example, as primary receiver, you may require secondary receivers to perform 
some action, such as shipping goods or waiting for expiration of a return 
period, before making payment. To complete the payment, you must explicitly 
execute a payment to secondary receivers after the sender pays you. The 
payment must occur within 90 days, after which you cannot complete the payment 
as part of the original chained payment.

Step 4: Make a Payment to One or More Secondary Receivers

When the time comes to pay secondary receivers, call ExecutePayment, 
specifying the pay key from Step 1. For more information on this call, see 
the ExecutePayment API Operation.

When the time comes to pay secondary receivers, all secondary receivers must 
be paid at once.

PayKey + ExecutePayment = ANSWER!
