## Introduction

[Change log of lexoffice](https://developers.lexoffice.io/docs/#change-log).

## lexoffice Authentication

Authentication is simply done via an API Key or Access key, as described [here](https://developers.lexoffice.io/cookbooks/public-api/#lexoffice-api-kochbuch-public-api). API Keys can be generated and [changed here](https://app.lexoffice.de/login?redirect=%2Fsettings%2F%23%2Fpublic-api), after logging in.

## Special notes

When creating a contact, you can either create a contact or a company in the same request, not both (as you can see in the UI).

Webhooks and events can be registered [here](https://developers.lexoffice.io/cookbooks/public-api/#events-und-webhooks).
