我正在使用电子商务.完成付款后,应该将其捕获并且几天后,应该从客户帐户处理或扣除.

示例：如果客户使用Paypal初始付款,那么它将是“授权”&在特定交易转换为“销售”之后(最多21天)意味着已处理.

客户可以使用信用卡付款.我们可以使用Paypal或需要使用其他付款方式吗？

据我所知：在Paypal SDK API中,您必须创建该支付再次&然后过程.但我已经有了交易ID.那么需要再次创建付款吗？

Paypal: How to Capture Authorized Payment?

http://paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/AuthorizationCapture.html

最佳答案 添加composer.json

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