我正在使用电子商务。付款完成后，应将其捕获，几天后应对其进行处理或从客户帐户中扣除。

示例:如果客户使用 Paypal 首字母付款，它将被“授权”并且在(最多 21 天)特定交易转换为“销售”意味着处理。

客户可以使用信用卡付款。我们可以使用 Paypal 实现还是需要使用其他付款方式？

据我所知:在 Paypal SDK API 中，您必须再次创建付款，然后再进行处理。但是我已经有了交易 ID。所以需要重新创建付款吗？

Paypal: How to Capture Authorized Payment?

最佳答案

加入composer.json

"require": {
        "paypal/rest-api-sdk-php": "*"
    }

看yii中的代码示例
