PayPal交易可以包括第三方吗? [英] Can a PayPal transaction include a third party?

问题描述

情况如下:有一个连接买卖双方的网站，例如Ebay.

The situation is as follows: there's a website that connects sellers and buyers, like Ebay.

除其他事项外，网站所有者还需要了解从此处初始化的每笔交易的详细信息.本质上，我正在寻找一种可以返回数字收据的付款方式.

Among other things the owner of the website needs to know the details of each transaction initialized from there. Essentially I am looking for a payment method that returns a digital receipt.

是否可以使用PayPal做类似的事情?

Is it possible to do something like that with PayPal?

推荐答案

当然，您可以这样做.

Of course you can do it like this.

必须要做的事情:

1. 已经让卖家注册了他们的PayPal信息.假设在卖家"表中，以商家电子邮件地址/商家ID作为主键.
2. 卖家必须在其PayPal帐户上设置IPN URL.网址必须指向您将创建的IPN处理程序
3. 处理IPN，请检查 http://boolcast.com/joomla/3-development/13-joomla-custom-paypal-ipn .我曾为Joomla编写过PayPal IPN处理程序，您可以随时对其进行修改，并根据需要使用它(您必须从配置中删除商家信息).这也是您将收到的

1. Have sellers register their PayPal information with. Lets say in "sellers" table, with merchant email/ merchant id as primary key.
2. Sellers will have to setup IPN URL on their PayPal accounts. There url will have to point to the IPN handler that you will create
3. Handle the IPN, check this out http://boolcast.com/joomla/3-development/13-joomla-custom-paypal-ipn. I wrote that PayPal IPN handler for Joomla a while back, you can eaily modify it and use it for what you need (you will have to remove merchant info from config). Also here is a list of IPN vars that you will receive https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_admin_IPNReference
4. If IPN is good, While handling the IPN check the receiver_email and/or receiver_id to determine who is the seller. You can retrieve the seller information from "sellers" table by the email/merchange_id. At this point you can generate all kinds of notifications to seller/buyer/yourself/etc...

注意事项:

• 如果非主要的PayPal用户将要创建PayPal按钮，则您将无法使用商家ID.
• IPN变量列表将取决于付款类型以及付款方式
• 始终使用 PayPal沙箱
