When you log into the Smartcar developer portal, you'll receive a set of parameters needed to (1) let users authenticate with their cars using Smartcar and (2) make requests to the Smartcar API after a user has authenticated with their vehicle.

The parameters in the application configuration are used as follows:
Client ID: this is the unique, public identifier of your app
Client secret: this value is known only to you (the app developer) and Smartcar's authorization server. Treat this like a password.
Redirect URI: this is the url that Smartcar will redirect to after successfully authenticating a user with their vehicle (if you're running our demo app, this would be http://localhost:8000/callback)
To learn more about these configuration parameters and how to use them to authenticate with Smartcar, please refer to our docs.
