当持卡人发起信用卡交易时，卡组织会向 Tevau-Api 平台发送授权交易 Webhook 通知。Tevau-Api平台在完成内部校验（卡余额、企业余额、风控规则等）后，若该企业开启了 JIT（Just-In-Time）授权功能，将通过本接口向下游企业发起同步授权请求，由企业自行决定是否批准该笔交易。下游企业收到授权请求后，必须在 2 秒内同步返回 HTTP 响应。1.
接口性能：确保回调接口响应时间 < 1.5 秒（预留网络传输时间），超过 2 秒将被视为超时拒绝
2.
决策逻辑：仅需返回 APPROVED 或 DECLINED，复杂的审批流程应在内部异步处理，同步接口只返回最终决策
3.
日志记录：建议下游企业对每次回调的请求和响应做完整日志记录，便于对账和问题排查
