使用Square作为Opencart 3.0.3.2版上的支付网关。在我们提供优惠券和折扣之前，一切都很好。
优惠券是在OpenCart中创建的，可提供10％的折扣。 当客户购买并应用代码时，它将提供正确的折扣。 然后，客户继续付款。 Square成功处理付款，而不是返回成功消息，而是返回错误。订单立即被取消。 SQUARE仪表板上显示的付款成功。
显示给客户的确切错误消息是： 意外的网站错误。请通过+44 1234567或通过电子邮件admin@myemail.com与商店所有者联系。请注意，您的交易可能会被处理。“
很多时候，客户再次尝试并最终在卡上产生多次费用，这需要几天的时间才能退款。
已经梳理了整个互联网以寻求解决方案。
iSenselab对我说：“一旦订单被正方形确认，也会将响应发送回分机。”因此，我怀疑某个地方的某些回调函数不匹配。折扣价格低于预期价格，并会引发错误或某些阻滞。
任何帮助将不胜感激。请让我知道您可能需要什么。 我在Opencart上启用了调试功能，并捕获了以下内容-
