Usage Example

void UYourClass::RestoreWithdrawal(const FString& WithdrawalKey)
{
    FWithDrawalRestore::Send(
        WithdrawalKey,
        FOnWithDrawalRestoreSuccess::CreateLambda([](const FString& Response)
        {
            FWithDrawalRestore::FRes Result;
            if (Result.FromJson(Response))
            {
                UE_LOG(LogTemp, Log, TEXT("Account restoration completed: %s"), *Result.Status);
                UE_LOG(LogTemp, Log, TEXT("You can now use the game normally."));
            }
        }),
        FOnWithDrawalRestoreError::CreateLambda([](const FString& Error)
        {
            FWithDrawalRestore::FRes Result;
            if (Result.FromJson(Error))
            {
                UE_LOG(LogTemp, Error, TEXT("Account restoration failed: [%s] [%s]"),
                    *Result.ErrorCode, *Result.Message);

                if (Result.ErrorCode == TEXT("WITHDRAWAL_PERIOD_EXPIRED"))
                {
                    UE_LOG(LogTemp, Error, TEXT("Grace period has expired, account cannot be restored."));
                }
            }
        })
    );
}

Getting WithdrawalKey

The withdrawal_key can be obtained when requesting withdrawal or through the token status check API. Recovery is only possible within the grace period; after the grace period expires, the account cannot be restored.
