Scheduled webhooks make it incredibly easy to receive vehicle data on a cadence of your choosing. You can set up a webhook for any Smartcar endpoint that allows you to read data from a vehicle.

Scheduled

Scheduled Webhooks

Dynamic webhooks make it incredibly easy to receive data from a vehicle at the optimal frequency supported by the OEM. Specifically, once a certain condition is met, you will be able to receive data more frequently from the vehicle to stay up-to-date with the state of the vehicle when it matters most to you.

Dynamic (Early Access)

Dynamic Webhooks (Early Access)

Diagnostic webhooks send events whenever a state change occurs within the vehicle's Health Status or a Diagnostic Trouble Code (DTC) is reported

Diagnostic (Early Access)

Diagnostic Webhooks (Early Access)

A comprehensive breakout of all Smartcar errors.

Overview

This error occurs when a user denies your application access to the requested scope of permissions.

Access Denied

This error occurs when a user’s vehicle is compatible but their connected services subscription is inactive because either it has expired or it has never been activated.

Invalid Subscription

This error occurs when the user has encountered an Error page in Connect and has chosen to return to your application.

Configuration

This error occurs when a vehicle owner has a connected services account, but there are no vehicles associated with the account.

No Vehicles

If there is a server error, the user will return to your application.

Server

This error occurs when a user tries to authorize an incompatible vehicle in Smartcar Connect.

Vehicle Incompatible

This error occurs when a user went to authorize directly with the OEM but exited the flow for some reason.

OEM Login Cancelled

This error occurs when a user leaves the Connect flow after hitting **Back to application** before granting your application access to their vehicle.

User returned to application

Thrown when there is an issue with your authorization header.

Authentication

Authentication Errors

Thrown when limits have been reached based on your plan, or if the feature is not avaible.

Billing

Billing Errors

Thrown when Smartcar does not support a make, or feature for a vehicle.

Compatibility

Compatibility Errors

Thrown when there are issues with the user's connected service account.

Connected Services Account

Connected Services Account Errors

Thrown when Smartcar does not support a make or feature for a vehicle.

Permission Errors

Thrown when there is an issue with the frequency of your requests.

Rate Limit

Rate Limit Errors

Thrown when the incorrect API version is used or when the endpoint URL is incorrect.

Resource Not Found

Thrown when Smartcar runs into an unexpected issue and was unable to process the request.

Server Errors

Thrown when the OEM servers or vehicle failed to process the request.

Upstream

Upstream Errors

Thrown if there is an issue with the format of the request or body.

Validation

Validation Errors

Thrown when a request fails due to the state of a vehicle or logically cannot be completed e.g. you can't start a vehicle charging if it's not plugged in.

Vehicle State

By launching Connect in [simulated mode](/docs/connect/advanced-config/modes), you're able to test your application against certain errors.

What is Connect?

Our SDKs make integrating Smartcar fast and easy in different languages and frameworks.

Dashboard Configuration

Build the Connect URL

Upon successfully accepting the permissions, Smartcar will redirect the user back to your application using the specified `REDIRECT_URI`, along with an authorization code as a query parameter. In the case of on error, we'll provide an error and description as parameters instead.

Handle the Response

Auth Code Exchange

After fetching your first token pair, you'll need to manage them in order to maintain access to the vehicle.

Your access token will expire **2 hours** after it is issued. When this happens, your application  can retrieve a new one by using the corresponding `REFRESH_TOKEN`.

Refreshing Access Tokens

Refresh tokens expire after **60 days ordinarily** or **after 1 minute when used to fetch a new token pair**.

Refreshing Refresh Tokens

Redirect to Connect

If the re-auth is successful, the redirect to your application will contain a vehicle ID. In the case of an error, we'll provide an error and description as parameters instead.

Connect can be launched with three different workflows. Depending on your use case and what information you have about the vehicle ahead of a launching Connect, you may be able to leverage one of these flows for a more streamlined Connect experience.

Connect Flows

Modes

By default Connect will launch based on the devices location impacting the brands that are available to the user e.g. Renault is only available in Europe.

Smartcar API Reference

Headers

To interact with the Smartcar API, you will need to exchange your authorization code from the [Connect redirect](/docs/connect/handle-the-response) for an access token.

Your access token will expire 2 hours after it is issued. When this happens, your application can retrieve a new one by using the `refresh_token` returned in the [auth code exchange](/docs/api-reference/authorization/auth-code-exchange) or prior token refresh.

Token Refresh

Makes

In order to use an endpoint or webhook, you'll need to request the associated permissions from your user in [Connect](/docs/connect/what-is-connect).
