How can we help?

If you have called the Alipay declaration API to submit the payment info, but the customs E-port system still shows that the payment info is missing, please check according to the following steps:

1. Call the Declaration Query Interface to check the declaration status. The payment info is only received by the E-port system when the value of customs_code is 2.
2. If the E-port system has received the payment info, but still shows that the payment info is missing, please check whether the transaction ID in the submitted transaction info is:

• The value of the out_trade_no in the Alipay payment API if the value of is_split is T.
• The value of sub_out_biz_no in the request of alipay.acquire.customs API.

在您成功调用支付宝海关报关接口后，在清关是，对应海关却仍返回对应的支付单不存在，此时需核对以下信息：

1、尝试调用支付宝海关报关查询接口Declaration Query Interface查询此时的推送状态，当同步返回中的customs_code为2 即：新增支付单成功时，说明对应海关已经成功接收到该支付单。

2、在核实步骤1后，对应海关仍返回无对应的支付单，请核对贵司在推送订单时，订单上的订单号码是否是：

2-1 支付接口中的out_trade_no（不拆单时）

2-2报关接口中的sub_out_biz_no（拆单申报时）
