## Introduction

Lexoffice is a German cloud-based accounting solution designed for the German market that helps businesses manage invoices, contacts, and financial documents.

## Configure Lexoffice

**Prerequisite(s)**

* No prerequisite to enable Lexoffice. Chift supports only the <i>public</i>
  API.
* The public API has the limitation that it's only available for end-users having the XL plan.

**Activation Process**

* Activate the Lexoffice integration on the Chift platform.

## Test Lexoffice

To sign up for a new company, visit [https://app.lexware.de/signup](https://app.lexware.de/signup) and click on "Kostenlos registrieren".\
The signup only requires email and password.\
The created account can be used free within 30 days and has all available features. You can create as many accounts as you need.

## Connect Lexoffice

To activate a connection with Lexoffice, users will have to go through the following steps:

* French article: [Help Center - Lexoffice EN](https://help.chift.app/articles/6563737155-lexware-office-lexoffice)

## Technical Limitations

## Rate Limiting

Lexoffice API has standard rate limits to ensure fair usage across all applications. These limits are automatically managed by Chift to optimize performance and prevent interruptions. However, once the API rate limit is reached, Chift cannot bypass these limitations and requests will need to wait until the limit resets. For high-volume operations, it's recommended to plan accordingly and distribute requests over time. See more information [here](https://developers.lexware.io/docs/#api-rate-limits)
