问题描述
我是Braintree API的新手。我正在使用定期付款。为此，我使用的是Braintree提供的Drop-In UI。一切顺利，但只显示两个字段：卡号和到期月/年；和Paypal按钮。它没有显示CVV字段。
I'm fairly new to Braintree API. I'm using Recurring Payments. And for that I'm using Drop-In UI that is provided by Braintree. Everything goes well but it only shows two fields: Card Number and Expiration Month/Year; and the Paypal button. It's not showing CVV field.
我相信CVV字段是可选的，如果我不接受，交易仍然会进行。但是我想知道为什么它没有显示出来？
I believe the CVV field is optional and the transaction will still go through if I were to not accept it. But I'm wondering why is it not showing up?
Braintree的新文档非常有限。而且我在他们的网站上找不到关于此问题的太多信息。任何指针将不胜感激。谢谢。
Braintree's new documentation is very limited. And I can't find much info on this problem their website. Any pointers will be much appreciated. Thanks.
推荐答案
转到设置->处理-> CVV，启用CVV验证规则，并续订客户端令牌。
go to Settings -> Processing -> CVV, enable CVV verification rules, and renew the client token.
通过这种方式，CVV字段将出现在Drop-in UI中。
In this way the CVV field will appear in the Drop-in UI.
