API reference documentation

FINN APIs provide a way for FINN Partners to communicate with our services. You can use our APIs to retrieve information about cars, and manage car subscriptions.

Our APIs follow the REST architectural style. FINN APIs have resource-oriented URLs, expect request bodies and provide responses in JSON-encoded format, and use standard HTTP response codes and authentication options.

By default, all requests receive the latest version of our APIs. When we make major changes to one of our APIs, we release a new version. You can find an API's version number behind the API's name (for example, 1.0.0).
