[C#] Gameforge NoS0577 token generation

I'm just sharing some code i've made for a personnal project, allowing you to easily generate NoS0577 token since it's looks like it's the only way to connect for newest accounts, it can be useful if you want to create a C# clientless application.

Code:

public sealed class GameforgeAuth : IGameforgeAuth
{
    private const string URL = "https://spark.gameforge.com/api/v1";
    private const string USER_AGENT = "GameforgeClient/2.0.48";
    private const string MEDIA_TYPE = "application/json";
    
    private readonly HttpClient _httpClient;

    public GameforgeAuth()
    {
        _httpClient = new HttpClient();
    }

    public async Task<string> GetAuthToken(string email, string password, string locale, Guid installationId)
    {
        string json = JsonConvert.SerializeObject(new AuthRequest
        {
            Locale = locale,
            Email = email,
            Password = password
        });
        
        using var request = new HttpRequestMessage(HttpMethod.Post, $"{URL}/auth/sessions")
        {
            Content = new StringContent(json, Encoding.UTF8, MEDIA_TYPE)
        };
        request.Headers.Add("TNT-Installation-Id", installationId.ToString());
        
        HttpResponseMessage response = await _httpClient.SendAsync(request);
        if (!response.IsSuccessStatusCode)
        {
            return string.Empty;
        }
        
        string content = await response.Content.ReadAsStringAsync();
        Dictionary<string, string> jsonContent = JsonConvert.DeserializeObject<Dictionary<string, string>>(content);

        return jsonContent.GetValueOrDefault("token") ?? string.Empty;
    }

    public async Task<IEnumerable<GameforgeAccount>> GetAccounts(string token, Guid installationId)
    {
        using var request = new HttpRequestMessage(HttpMethod.Get, $"{URL}/user/accounts");
        
        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
        request.Headers.Add("User-Agent", USER_AGENT);
        request.Headers.Add("TNT-Installation-Id", installationId.ToString());
        
        HttpResponseMessage response = await _httpClient.SendAsync(request);
            
        if (!response.IsSuccessStatusCode)
        {
            return new List<GameforgeAccount>();
        }
            
        string content = await response.Content.ReadAsStringAsync();
        Dictionary<string, GameforgeAccount> jsonContent = JsonConvert.DeserializeObject<Dictionary<string, GameforgeAccount>>(content);

        return jsonContent?.Values.ToArray() ?? Array.Empty<GameforgeAccount>();
    }

    public async Task<string> GetSessionToken(string token, GameforgeAccount gameforgeAccount, Guid installationId)
    {
        using var request = new HttpRequestMessage(HttpMethod.Post, $"{URL}/auth/thin/codes");
        
        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
        request.Headers.Add("User-Agent", USER_AGENT);
        request.Headers.Add("TNT-Installation-Id", installationId.ToString());
        
        string json = JsonConvert.SerializeObject(new SessionRequest
        {
            PlatformGameAccountId = gameforgeAccount.Id
        });

        request.Content = new StringContent(json, Encoding.UTF8, MEDIA_TYPE);

        HttpResponseMessage response = await _httpClient.SendAsync(request);

        if (!response.IsSuccessStatusCode)
        {
            return string.Empty;
        }

        string content = await response.Content.ReadAsStringAsync();
        Dictionary<string, string> jsonContent = JsonConvert.DeserializeObject<Dictionary<string, string>>(content);

        return (jsonContent.GetValueOrDefault("code") ?? string.Empty).ToHex();
    }
}

Code:

public sealed class GameforgeAccount
{
    public string Id { get; set; }
    
    [JsonProperty("displayName")]
    public string Name { get; set; }

    public override string ToString() => $"{nameof(Id)}: {Id}, {nameof(Name)}: {Name}";
}

Code:

public sealed class GameforgeAccount
{
    public string Id { get; set; }
    
    [JsonProperty("displayName")]
    public string Name { get; set; }

    public override string ToString() => $"{nameof(Id)}: {Id}, {nameof(Name)}: {Name}";
}

Code:

public sealed class SessionRequest
{
    [JsonProperty("platformGameAccountId")]
    public string PlatformGameAccountId { get; set; }
}
