Copilot via API — Developer Documentation

Welcome to the developer documentation for Copilot via API by Haufe.

Copilot via API lets you integrate Haufe's AI-powered copilots — specialized in domains such as Tax, HR, and Sustainability — directly into your own applications.

What you'll find here

  • Start here — How to get access and a step-by-step quickstart guide to make your first API call.
  • Understand the API — Concepts, workflows, error handling, anonymization, and API key management.
  • Migration — Moving from the old infrastructure to the new base URL.

Getting started

If you are new, head to the Quickstart Guide to get up and running quickly.

Work in progress

This documentation is actively being developed. If you have questions not covered here, please reach out to your Haufe contact person.

Migration

If you are already using Copilot via API on the old infrastructure (api.h-ai.haufe.io), see the Migration Guide to move to the new base URL.
