fortnite-2

A Java 11+ client for the APIs used by Epic Games Launcher and the Fortnite client

Features

• Authentication with Epic's APIs is managed internally
• Fetching and filtering (by platform, party type, and time window) of an account's Battle Royale statistics
• Fetching of all-time win leader boards using different combinations of platform and party type
• Fetching of a single account via its username or many accounts via their IDs
• Adding and removing friends, accepting and declining friend requests
• Fortnite EULA auto-accepting
• Two-factor authentication

Usage

Instantiating a client

This is the simplest way to instantiate a client:

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        final var fortnite = builder.build();
    }
}

If Epic Games ever deprecate this library's default launcher and client tokens, you may provide your own like this:

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword")
            .setEpicGamesLauncherToken("launcherToken")
            .setFortniteClientToken("clientToken");
        final var fortnite = builder.build();
    }
}

Fortnite's EULA can be automatically accepted and access can be granted to Fortnite's APIs like so:

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

public final class Main {

    public static void main(final String[] args) {
        try (final var fortnite = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword")
            .setAutoAcceptEulaAndGrantAccess(true)
            .build()) {
        }
    }
}

Cleaning up

When you no longer need your client instance, remember to terminate your Epic Games authentication session and release the client's underlying resources with a call to Fortnite.close(). Usage examples further in this document will make this call implicitly using try-with-resources statements.

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        final var fortnite = builder.build();
        fortnite.close();
    }
}

Fetching an account using its username

import io.github.robertograham.fortnite2.domain.Account;
import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var optionalAccount = fortnite.account()
                .findOneByDisplayName("RobertoGraham");
            // nothing printed if the response was empty
            optionalAccount.map(Account::accountId)
                .ifPresent(System.out::println);
            optionalAccount.map(Account::displayName)
                .ifPresent(System.out::println);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
        }
    }
}

Fetching an account using the session's account ID

import io.github.robertograham.fortnite2.domain.Account;
import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var optionalAccount = fortnite.account()
                .findOneBySessionAccountId();
            // nothing printed if the response was empty
            optionalAccount.map(Account::accountId)
                .ifPresent(System.out::println);
            optionalAccount.map(Account::displayName)
                .ifPresent(System.out::println);
        } catch (final IOException exception) {
            // findOneBySessionAccountId unexpected response
        }
    }
}

Fetching many accounts using their IDs

import io.github.robertograham.fortnite2.domain.Account;
import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;
import java.util.Collections;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var accountId1String = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .map(Account::accountId)
                .orElse("");
            final var accountId2String = fortnite.account()
                .findOneByDisplayName("Ninja")
                .map(Account::accountId)
                .orElse("");
            // accountSet will be empty if the response was empty
            // OR if every account ID was invalid
            final var accountSet = fortnite.account()
                .findAllByAccountIds(accountId1String, accountId2String)
                .orElseGet(Collections::emptySet);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountIds unexpected response
        }
    }
}

Statistic filtering API

Most basic filtering - by time windows

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var account = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .orElseThrow();
            final var accountIdString = account.accountId();
            // if any null then we received an empty response
            final var fromAccountAllTimeFilterableStatistic = fortnite.statistic()
                .findAllByAccountForAllTime(account)
                .orElse(null);
            final var fromAccountIdAllTimeFilterableStatistic = fortnite.statistic()
                .findAllByAccountIdForAllTime(accountIdString)
                .orElse(null);
            final var fromAccountCurrentSeasonFilterableStatistic = fortnite.statistic()
                .findAllByAccountForCurrentSeason(account)
                .orElse(null);
            final var fromAccountIdCurrentSeasonFilterableStatistic = fortnite.statistic()
                .findAllByAccountIdForCurrentSeason(accountIdString)
                .orElse(null);
            final var fromSessionAccountIdAllTimeFilterableStatistic = fortnite.statistic()
                .findAllBySessionAccountIdForAllTime()
                .orElse(null);
            final var fromSessionAccountIdCurrentSeasonFilterableStatistic = fortnite.statistic()
                .findAllBySessionAccountIdForCurrentSeason()
                .orElse(null);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountForAllTime unexpected response
            // OR findAllByAccountIdForAllTime unexpected response
            // OR findAllByAccountForCurrentSeason unexpected response
            // OR findAllByAccountIdForCurrentSeason unexpected response
            // OR findAllBySessionAccountIdForAllTime unexpected response
            // OR findAllBySessionAccountIdForCurrentSeason unexpected response
        }
    }
}

Filtering by platform and then party type

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

import static io.github.robertograham.fortnite2.domain.enumeration.PartyType.SQUAD;
import static io.github.robertograham.fortnite2.domain.enumeration.Platform.PC;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var account = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .orElseThrow();
            final var partyTypeFilterableStatistic = fortnite.statistic()
                .findAllByAccountForAllTime(account)
                .map(filterableStatistic -> filterableStatistic.byPlatform(PC))
                .orElseThrow();
            final var statistic = partyTypeFilterableStatistic.byPartyType(SQUAD);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountForAllTime unexpected response
        }
    }
}

Filtering by party type and then platform

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

import static io.github.robertograham.fortnite2.domain.enumeration.PartyType.SOLO;
import static io.github.robertograham.fortnite2.domain.enumeration.Platform.PS4;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var account = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .orElseThrow();
            final var platformFilterableStatistic = fortnite.statistic()
                .findAllByAccountForAllTime(account)
                .map(filterableStatistic -> filterableStatistic.byPartyType(SOLO))
                .orElseThrow();
            final var statistic = platformFilterableStatistic.byPlatform(PS4);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountForAllTime unexpected response
        }
    }
}

Inline platform and party type chained filter

import io.github.robertograham.fortnite2.implementation.DefaultFortnite.Builder;

import java.io.IOException;

import static io.github.robertograham.fortnite2.domain.enumeration.PartyType.DUO;
import static io.github.robertograham.fortnite2.domain.enumeration.Platform.XB1;

public class Main {

    public static void main(final String[] args) {
        final var builder = Builder.newInstance("epicGamesEmailAddress", "epicGamesPassword");
        try (final var fortnite = builder.build()) {
            final var account = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .orElseThrow();
            final var statistic = fortnite.statistic()
                .findAllByAccountForAllTime(account)
                .map((final var filterableStatistic) ->
                    filterableStatistic
                        .byPlatform(XB1)
                        .byPartyType(DUO)
                )
                .orElse(null);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountForAllTime unexpected response
        }
    }
}

FilterableStatistic, PartyTypeFilterableStatistic, and PlatformFilterableStatistic all extend Statistic. This means that you can make calls like Statistic.kills(), Statistic.wins(), etc. at each filtering stage to get narrower and narrower scoped values

            final var account = fortnite.account()
                .findOneByDisplayName("RobertoGraham")
                .orElseThrow();
            final var filterableStatisticOptional = fortnite.statistic()
                .findAllByAccountForAllTime(account);
            // prints 761 at time of writing
            filterableStatisticOptional.map(FilterableStatistic::kills)
                .ifPresent(System.out::println);

            )
                .map(Statistic::kills)
                .ifPresent(System.out::println);
        } catch (final IOException exception) {
            // findOneByDisplayName unexpected response
            // OR findAllByAccountForAllTime unexpected response
        }
    }
}

Leader board API

Name: TTV SwitchUMG, Wins: 251
Name: Twitch TheBigOCE, Wins: 201
Name: WE_桃子, Wins: 197
