# 预授权（以色列）

Tweezercomm 的预授权交易会根据支付服务器的响应进行处理、授权，并最终结算或取消。此流程还包括用于处理错误的弹性机制。

## 交易流程

要理解预授权交易流程，请参考以下事件顺序：

![](https://mintcdn.com/nayax-44d6e37b/gp-udlFbAMEECcYg/images/docs/tweezercomm-pre-authorization-israel/image1.png?fit=max\&auto=format\&n=gp-udlFbAMEECcYg\&q=85\&s=40203e7c36fdba2fb7d21d15a985a50f)

以下是每个步骤的详细说明：

1. The client application (POS) sends a [`doTransaction()`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/dotransaction-ashrait) request to the Nayax Device with a parameter (`Trancode=2`) to initiate a pre-authorization.
2. 持卡人插入、展示或刷卡。
3. Nayax 设备与支付服务器通信以执行预授权。
4. The payment server responds, and the Nayax Device relays the `Authorization result` back to the POS.
5. At a later time, the POS sends another [`doTransaction()`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/dotransaction-ashrait) request, this time with a parameter (`Trancode=3`) to initiate the completion of the pre-authorized transaction.
6. Nayax 设备与支付服务器通信以完成该交易。
7. The payment server responds with a `Completion result`, which the Nayax Device sends back to the POS.
8. At the end of the day, the POS sends a [`doPeriodic()`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/doperiodic) request. The Nayax Device communicates with the payment server to perform the settlement of the day's transactions and sends a [`doPeriodic()`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/doperiodic) result back to the POS.
