API Reference

These reference pages introduce the API specs that are available in Fortellis. The pages range from broad API descriptions for browsing to detailed information for coding with individual API endpoints (methods). The Try It Out feature lets you run test calls on the API endpoints to see sample calls, parameters, and responses.


Fortellis APIs are grouped by their domain in the automotive business. Domains cover front office functions (Sales) to fixed ops (Service).

The domains available can be seen on the left navigation split into different sections. Under each domain there are links to the available APIs under that domain. This is a great place to start browsing for APIs to use in your solution.

API Pages

Each API has its own page with a list of all the methods for the API. This page serves two purposes. It gives you a more detailed look at what you can do with the API, and it is how you access detailed information for the API endpoints.

Each name in the endpoint list opens to display more information.


On each API page, clicking on an endpoint will provide more details. Most of the information comes directly from the API spec. Look here for:

  • Resource URL
  • Data model (for POST and other payload methods)
  • Header and query parameters
  • Sample call: request, response, and cURL
  • HTTP error responses

Navigate to the first API here or choose one from the left to start exploring.
