![]() ![]() You should keep the access token around to avoid having to re-authenticate each time and you should also handle API access errors. Note that there are various tricks to using APIs like this. Running this little program simply shows my cars current mileage: From that data I can extract the current odometer reading. Then I use that connection object to request data about my car. In the example above I’m using my email address and password to log into the Tesla server (same one I would use to access the MyTesla portal when ordering the car and browsing the Tesla forums), and I am getting a connection object. I won’t be going into all the API calls and how they work, but I’ve provided a quick minimal working example that you can use to follow along: For those interested in libraries for other languages, I’ve found libraries for Java, Node, Ruby, and C#. The one that best suited me is Teslajson by Greg Glockner which is a small Python file containing all of the basics for interacting with the Tesla Mobile API. Searching around I found a few Python libraries to make integrating to the Tesla Mobile API easier. ![]() What language you choose to program in and whether you use a library is either defined by the needs of the project or the personal preference of the programmer.įor my hacking/playing around I use the Python programming language. While the documentation will allow you to immediately start programming, assuming you have a knowledge of how to interact with APIs, some folks have created libraries in various programming languages to assist with the basics of interacting with the Tesla Mobile API. There’s a free site called Apiary that can be used for documenting APIs and that was used to document the Tesla Model S API. Like many things these days, if it exists it can be figured out and some energetic Tesla owners have figured out how the API works. You can use applications Tesla has created that use the API but you’re not supposed to make your own applications using the API. This Mobile API is not documented by Tesla and is not intended to be used by anyone other than Tesla employees. The API we’re going to focus on is the one used by the mobile applications. Systems often have many APIs for different purposes. Start the car, vent the sunroof, honk the horn, are just some of the features that get invoked via an API whenever a user taps a button on their mobile device. The car itself is also using one or more APIs to talk to Tesla to get software updates, send debugging information to Tesla, etc. Tesla’s iOS and Android mobile app for instance connects to a set of APIs that allows the app to communicate with your Tesla. Security enforces that you are who you say you are, and that you’re allowed to use a set of features exposed through the interface. ![]() APIs come in a variety of types, each including its own security model that requires authentication before the API is useable. Whenever you’re dealing with connected devices, especially if they’re interacting over-the-air, they’re likely using APIs to communicate with one another. Tesla Mobile APIĪn API is a specification for programs to interact with one another through a piece of software. Read on if you’re interested in learning more about the undocumented application programming interface (API) to your Model S and Model X, and exploring its capabilities. Occasionally I geek out on some of the more technical aspects of owning my Model S, and today is going to be one of those days. ![]()
