How to connect to Lexware Office

To allow your customers to link your application with their Lexware Office account, you need to set up a Lexware Office App and submit your application credentials to maesn.

Note that there are two versions of the Lexware Office API: A Public API and a Partner API. The partner API has access to a wider range of endpoints and data than the public API and is the API you get access to through maesn..

1

Prerequisites

Before you begin, make sure you have the following:

To get a Lexware Office client configured, you need to establish contact with the Lexware Office partner programme (see section below) and supply them the details of your integration including the scopes required.

2

Configure your integration in the maesn API

Next we configure your API tenant with your client’s details:

  • Get in touch with your contact person at maesn to submit the client id and client secret.

If you are not sure who your technical contact is, don’t hesitate to reach out to us via support@maesn.com, but do not enter your client credentials directly in the email. That’s not safe!

Sandbox environment

Lexware Office has different URLs and credentials for their production and sandbox environments. To generate a sandbox end user account you have to use the lexoffice-sandbox target system. You also have to use the following callback URL for the sandbox environment: https://api.maesn.dev/auth/callback/lexoffice-sandbox
