Requirements

Connecting Lexware Office takes an active account plus an API access token from your account settings — no other setup is required.[3]https://office.lexware.de

Get your Lexware Office credentials

API KeypasswordRequired
In Lexware Office, open Add-ons, then Public API (app.lexware.de/addons/public-api), and create a key. If you limit its permissions, include every area this workflow uses, for example invoices or contacts. Keys expire after 24 months.

Connect Lexware Office in WEXTL

Log in to your WEXTL account, add the Lexware Office node module to your workflow, and click Create new credential.
Instant triggers use webhooks — click Create a webhook first when adding one, then create the credential.
Optional: In the Credential name field, enter a name for the credential.
Enter the authentication credentials you copied from your Lexware Office account, or follow the on-screen instructions to create the credential.
If prompted, authenticate your account and confirm access.
If you want to make changes to your credential in the future, follow the steps in Manage credentials →

Notes

Credentials are org-scoped; share them with teammates from the Credentials picker on any of its nodes.For detailed information on connecting an application, see Connect an application →
