Overview
Smartcar is a connected car API that lets you read vehicle data (odometer, fuel level, location) and send commands (lock/unlock) to real cars with owner permission. It uses OAuth 2.0 so vehicle owners securely authorize your app — similar to how apps request Google account access. It works across most modern cars from major brands without needing brand-specific integrations.
Beginner Tip
Use Smartcar's test mode during development — it provides a simulated vehicle so you can build and test your app without needing a real car. When you're ready to go live, vehicle owners will connect their cars through Smartcar Connect, an OAuth flow you embed in your app.
