API Dictionary / Mini Program Payment / Query Order API

Query Order API

Latest update time：2022.08.04 Release notes

This API can be used to query all WeChat Pay orders. Merchants can use the Query Order API to query the order status and then complete subsequent business logic.

Tips：

Scenarios where the Query API should be called:

• The merchant system does not receive any payment notification due to an error of the merchant backend, network, server, etc.

• A system error is returned or the transaction status is unknown after the payment API is called.

• The USERPAYING status is returned after the Quick Pay API is called.

• The payment status needs to be confirmed before the order closure or cancellation API is called.
