paypal - 如何使用 PHP 实现 Paypal 链式支付

Question

尽管我之前已经实现了传统的贝宝网关 API，但我对贝宝支付网关还是很陌生。但是我对如何实施 Paypal 链式支付感到有点困惑，因为我去过贝宝文档网站，而且我似乎被一大堆信息所淹没。任何关于我如何以简单的方式实现它的链接或教程都将非常感激。

I'm going to second Sumit Neema's answer.

EDIT Unfortunately, it seems paypal-labs is out of commission. What a shame. Here's an updated link to the Adaptive Payments PHP sample code:

https://github.com/paypal/codesamples-php/tree/master/AdaptivePayments/sample/code

The thing that trips most people up, is how money flows in a chained payment.

On a chained payment you will have one primary receiver, who is the one that the customer sees, and upt to five secondary receivers (Invisible to the paying customer).

initially 100% of the money will move from the buyer to the primary receiver, and then, paypal will subtract from the primary whatever portion belongs to the secondary receiver(s).

For example, a $100 payment needs to be split 70/30 between primary and secondary.

Initially $100 will be in the primary receiver's account. Paypal will then take $30, and move it to the secondary.

The end result? Primary has $70, secondary has $30.

Hope this helps.
