Aydsko iRacing Data API

iRacing is the leading online racing simulation for PC. During events hosted via the iRacing service there is a large amount of data created related to race results and member participation in events.

This library allows access via .NET to the iRacing "Data API". These APIs allow a properly authenticated user a supported method of accessing data from the service.

⚠ Multi-Factor Authentication Requirement

iRacing has announced that they now require multi-factor authentication (MFA) for all users by default. This will affect the ability to use the iRacing Data API by logging in with a username or password.

In the immediate future, use of the Data API will be supported by enabling "Legacy Authentication" in your iRacing account settings. iRacing will advise next steps for the authentication of applications for the Data API later on.

To continue to use this library you must enable "Legacy Authentication" in your iRacing account settings before attempting to authenticate. Please do not enable this setting unless you require it, as it may reduce the security on your iRacing account.

Getting Started

1. Install the Aydsko iRacing Data API library.

The library is distributed as the Aydsko.iRacingData NuGet package. Install using your package manager of choice.

dotnet add package Aydsko.iRacingData

2. Register the client.

Register the iRacing Data API client classes with the service provider.

services.AddIRacingDataApi(options =>
{
    options.UserAgentProductName = "MyApplicationName";
    options.UserAgentProductVersion = new Version(1, 0);
});

3. Use the client.

Use the IDataClient from the service provider to authenticate and request data.

// Retrieve an instance from the service provider.
var dataClient = serviceProvider.GetRequiredService<IDataClient>();

// Supply your iRacing username and password.
dataClient.UseUsernameAndPassword(iRacingUsername, iRacingPassword);

// Retrieve information about our own account.
var infoResponse = await dataClient.GetMyInfoAsync(cancellationToken);

// Write that information to the console.
Console.WriteLine($"Driver name: {infoResponse.Data.DisplayName}");
Console.WriteLine($"Customer ID: {infoResponse.Data.CustomerId}");
Console.WriteLine($"Club: {infoResponse.Data.ClubName}");

Enable Caching of Results

1. Add the Microsoft memory caching package.

dotnet add package Microsoft.Extensions.Caching.Memory

2. Register the memory caching library with the service provider.

services.AddMemoryCache();

3. Register the caching client.

Register the iRacing Data API caching client classes with the service provider.

services.AddIRacingDataApiWithCaching(options =>
{
    options.UserAgentProductName = "MyApplicationName";
    options.UserAgentProductVersion = new Version(1, 0);
});

Then simply use the IDataClient as before.

Versioning

Ideally you should always use the latest version of the library that is available. This is because iRacing will sometimes introduce API changes during a release which make the old code incompatible.

This library will use version numbers will be in the format:

[YY][SS].[R]

Where:

• YY = two digit year
• SS = the iRacing season the library release was made in as a zero-padded number (i.e. 01, 02, 03, 04)
• R = release number, which increments when changes are made although it may not be sequential

Example:

• 2303.1 = changes compatible with iRacing 2023 Season 3 or later, and is release 1 during this season

Contributing

Before you begin a contribution, please read and ensure you are comfortable with this project's Code of Conduct.

To build & develop on the codebase you'll need:

• An active iRacing membership
• .NET 8 (or later)

To get started open and build src\iRacing Data API.sln.
