推荐答案

对于授权和捕获:

要进行付款授权，您必须在 paymentmethod 参数中传递authorization"而不是sale"

To make a payment authorize you will have to pass "authorization" in paymentmethod parameter instead of "sale"

  <input type="hidden" name="paymentaction" value="authorization" />

因此，对于这种类型的付款，paypal 不会立即向发件人收费，而是会等到收件人确认.有两种方法可以获取这笔付款:

So, For this type of payment, paypal will not charge the sender immediately but will wait till receiver confirmation. To capture this payment two methods are available:

1. 接收方将点击帐户中的捕获按钮
2. 它可以通过 API 完成 - 捕获付款使用 DoCapture 并取消付款使用DoVoid

1. Receiver will either click on capture button in account
2. It can be done via a API - to capture the payment use DoCapture and void the payment use DoVoid
