Usage Example

void UYourClass::LinkCustomAccount(const FString& UUID)
{
    FCustomLink::Send(
        UUID,
        FOnCustomLinkSuccess::CreateLambda([](const FString& Response)
        {
            FCustomLink::FRes Result;
            if (Result.FromJson(Response))
            {
                UE_LOG(LogTemp, Log, TEXT("Custom account link completed: %s"), *Result.Status);
            }
        }),
        FOnCustomLinkError::CreateLambda([](const FString& Error)
        {
            UE_LOG(LogTemp, Error, TEXT("Custom account link failed: %s"), *Error);
        })

}

Use Cases

This API is used to link a specific request UUID with the currently logged-in account. For example, it can be used to link a UUID generated from a web page with a game client, or for cross-platform account linking.
