排查与解决建议
- 验证AMEX卡CVV格式:AMEX的CVV为4位数字,其他卡为3位,确认创建
source时是否正确提交了4位CVV,避免因格式不符导致验证失败。 - 确认测试卡有效性:检查使用的AMEX测试卡是否为Clover沙箱官方提供的有效测试卡,部分第三方测试卡可能触发发卡行模拟拒绝规则。
- 核对请求参数差异:对比成功与失败请求的所有参数,确认除
source外其他参数完全一致;部分场景下AMEX可能需要额外参数,可查阅Clover官方文档确认。 - 检查商户AMEX权限:确认沙箱环境下的商户账号是否已开通AMEX支付通道权限,部分商户默认未启用该卡种。
- 联系Clover技术支持:若以上排查无结果,提供失败请求的
chargeID(KS1DF4QDJCB6M),请求官方查询具体拒绝原因,沙箱环境可能存在特殊的发卡行配置。
