Use Metadata to Store Additional Information

In this scenario, the player has had the opportunity to write / select their country to be displayed on the Leaderboard.

Unity

string leaderboardKey = "my_leaderboard";
int score = 1000;
string metadata = "country:" + PlayerPrefs.GetString("PlayerAssignedCountry");

LootLockerSDKManager.SubmitScore("", score, leaderboardKey, metadata, (response) =>
{
    if (!response.success) {
        Debug.Log("Could not submit score!");
        Debug.Log(response.errorData.ToString());
        return;
    } 
     Debug.Log("Successfully submitted score!\n with metadata: " + metadata);
});

Blueprint example of submitting a score with country as metadata

Unreal CPP

The header file for the SubmitScoreHandler should look like this:

#pragma once

#include "CoreMinimal.h"
#include "LootLockerSDKManager.h"

DECLARE_DELEGATE_OneParam(FOnSubmitScoreResponse, FLootLockerSubmitScoreResponse);

class YOURPROJECTNAME_API SubmitScoreHandler
{
public:
	SubmitScoreHandler();
	void SubmitScore(int score);
	~SubmitScoreHandler();
	
private:
	FString metadata;
	FString leaderboardKey;

	void OnSubmitScoreResponse(FLootLockerSubmitScoreResponse Response);

};

The cpp file should look something like this:

#include "CountrySubmit.h"

CountrySubmit::CountrySubmit()
{

}

void SubmitScoreHandler::SubmitScore()
{
	metadata = "Country:" + FunctionWhichGetsCountry();

	ULootLockerSDKManager::SubmitScore("", 
		leaderboardKey, 
		score, 
		metadata, 
		FOnSubmitScoreResponse::CreateUObject(this, &CountrySubmit::OnSubmitScoreResponse));
}

void SubmitScoreHandler::OnSubmitScoreResponse(FLootLockerSubmitScoreResponse Response)
{
	if (!Response.success) {
		UE_LOG(LogTemp, Log, TEXT("Error: %d"), Response.ErrorData.Message);
		return;
	}

	UE_LOG(LogTemp, Log, TEXT("Score submitted successfully. Rank: %d"), Response.rank);
}
