【英文标题】：what is Client side certificate in paytm payment gateway integration in android?

【问题描述】：

我几乎与以下this link集成了paytm支付网关

paytm 支付网关集成中的客户端证书是什么？他们提到它应该包含在原始文件夹中。我在哪里可以获得客户端证书？

仅供参考：即使在the sample paytm integration app 中也不包含客户端证书

【参考方案1】：

您可以将其作为 null 传递。文档中也提到了

inCertificate 是持有证书信息的对象。 如果商家没有使用客户端证书（如 上面的先决条件部分中给出）

【讨论】：

如果我使用 null，它会显示 找不到客户端证书 并在交易过程中停止为 Cannot POST /

你能发布完整的错误日志吗？开发人员在集成 paytm 网关时遇到的主要问题是哈希问题

你说的完全正确。我犯了一个错误，发送了错误的手机号码（不是 10 位数字）。就我而言，这就是错误。任何方式谢谢你:)

【参考方案2】：

我建议您使用 PGSDK 2.0 而不是不需要任何客户端证书

的旧版本
