Smartcar API Overview

The Smartcar API lets you read vehicle data, send commands, and manage connections across millions of vehicles through a single REST interface.

Smartcar provides two APIs: the Vehicle API and the Management API. Both use the same access token, obtained by exchanging your Client ID and Client Secret through API Authentication. Tokens are valid for 1 hour.

• API Authentication — How it works
• Request Access Token — Token endpoint reference
