Mercedes-Benz API

Vehicle / API Key Intermediate HTTPS
Varies by plan (check documentation)

Overview

The Mercedes-Benz API platform provides access to connected vehicle features including telematics data, remote vehicle controls, car configurator, and dealer locator services. It is aimed at developers building automotive apps, fleet management tools, or in-car experiences. An API key from the Mercedes-Benz developer portal is required.

Beginner Tip

Start with the sandbox mode on developer.mercedes-benz.com to test API calls without a real vehicle — it returns simulated data so you can learn the response structure risk-free. Each API product (Telematics, Remote Control, etc.) is a separate subscription in the portal.

Available Data

vehicle make and model
year and specifications
fuel economy
VIN decode data

Example Response

  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
