# UnionPay App Shows Transaction Succeeded but Cannot Be Found in UQPAY System

> How to troubleshoot when a UnionPay app transaction appears successful but is missing from the UQPAY system.

When a cardholder's UnionPay app displays a successful transaction that does not appear in the UQPAY system, request additional documentation from the cardholder.

Ask the cardholder to provide a screenshot of the E-bill details by navigating to:

**UnionPay app > Card Management > Transaction History > Transaction Details > E-bill Details**

This detailed information will help provide more context about the order and potentially explain the discrepancy between what appears in the UnionPay app and what is recorded in the UQPAY system.
