TeslaAuth library for C# / .NET Core

Helper library to authenticate to Tesla Owner API.

Includes support for MFA.

This code is heavily based on Christian P's work in the TeslaLogger tool. My changes were largely to make it reusable.

Thanks also to Tim Dorr for his work in documenting the new API, and Ramon Smits for his contributions to this library.


The package is available via NuGet with the package name TeslaAuth.

Install-Package TeslaAuth

There are two ways of using this library as described below.

Browser-assisted Example

Probably the most reliable way of using the library is to integrate a WebView into your application and have it show Tesla's login UI. This approach should be resilient to certain changes on Tesla's side, such as when they randomly decide to include (and later remove) a CAPTCHA on the login page. Since Tesla incorporated a CAPTCHA on their login page, it is no longer possible to authenticate using your own UI.

The Test.WPF project demonstrates a complete login and refresh flow. The sample only runs on Windows, but the library itself is cross platform (e.g. works on Xamarin).

The steps to use this approach are as follows:

  1. Initialise a TeslaAuthHelper instance
  2. Call authHelper.GetLoginUrlForBrowser() to generate the login URL
  3. Show the returned URL in your app's integrated browser
  4. Monitor the browser until you see a request for a URL containing the string "void/callback"
  5. Grab the entire URL (it contains a query string) and pass it to authHelper.GetTokenAfterLoginAsync(...)
  6. This will return a Tokens object containing an Access and Refresh token
  7. When the token expires, call authHelper.RefreshTokenAsync(...) to get a new one without needing a complete login flow.

Console Example

The other way to use the library is to build your own login UI. The library allows you to capture the user's email address, password and (if configured) multi-factor authentication code and send these directly to Tesla to obtain tokens. This approach works only when there is no CAPTCHA on the login page (it may or may not return).

The Test.Console project demonstrates a login and refresh flow using this approach.

The steps to use this approach are as follows:

  1. Initialise a TeslaAuthHelper instance
  2. Call `authHelper.Authenticate(...) with the user's credentials to obtain the tokens
  3. When the token expires, call authHelper.RefreshTokenAsync(...) to get a new one without needing a complete login flow.
