Smartcar’s backend SDKs are in maintenance mode. They receive security patches through December 1, 2026. After that date they will not be updated, including for security. The packages stay published and existing integrations keep working. For new integrations, call the API directly over HTTP with v3. If you rely on a backend SDK, move to direct HTTP before December 1, 2026 if you need continued security coverage, fixes, or capabilities the SDK does not support. See Making API Requests for per-language examples of each common task.

Java

Node.js

Python

Ruby


For the vehicle connection flow, see Connect SDKs (JavaScript, iOS, and Android), which are fully supported.
