# Callback Query

In daily operation, if the business callback fails due to abnormal factors such as changes in the callback address of the business platform and unstable network, and the order status is not updated, it can be viewed and processed in the project callback record.<br>

1. Click "API" in the Cregis client - > "History Callback" to display abnormal callback records by default. If the data is empty, it means that there is no abnormal callback data in the current project.<br>

2. If there is an abnormal callback that causes the order status of the business platform to not be timely updated, click the "Feed" button.<br>
