# H (Order status request)

The **`H` (Order Status Request)** message is used to check the status of specific orders in the system by providing either `OrderID` or `ClOrdID`.

The Revolut Crypto Exchange will normally respond with [**`8` (Execution Report)**](/docs/guides/exchange-fix-api/trading-fix-api/supported-fix-messages/fix-application-level-messages/message-8-execution-report).
