How to integrate Lexware Office in automation workflow?

3 simple steps to make your Lexware Office connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.

STEP 1

Select Lexware Office in workflow

Pick Lexware Office app in the workflow builder [4] - just one click to select the app.

STEP 2

Connect Lexware Office

When prompted, authorize access to Lexware Office in WEXTL once. Lexware Office credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].

WEXTL wants to integrate with your Lexware Office account. Approve?

STEP 3

Build a workflow

Build your workflow with Lexware Office yourself or with WEXTL® AI Builder. Connect Lexware Office to any available integrations [5], or use HTTP node to go beyond them.

How Lexware Office connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Lexware Office app is called in workflows. That allows your finance automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Lexware Office supports.

Full Lexware Office API documentation

The following table illustrates what fields Lexware Office integration require during authorization flow inside our workflow builder [4].

Demonstration of Lexware Office connection step inside WEXTL Workflow Builder [4].

Field	Type	Help
API KeyRequired	password	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 to popular apps on WEXTL

Enter a name of the other app you want to sync with Lexware Office below. Click on selected app to explore integration options with Lexware Office. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.

Example automation with Lexware Office integration

Select Watch Vouchers trigger from Lexware Office - this will be a starting point in your automation. Whenever event happens in Lexware Office, workflow will start [7] from Watch Vouchers node.

Search for Create a Bookkeeping Voucher, connect it as the next step of integration sequence. You can use filters between Watch Vouchers and Create a Bookkeeping Voucher, so only important data pass from Watch Vouchers to the next step. WEXTL gives you full control over the process of Lexware Office automation. All parts of workflow are visible on the canvas [4].

Lexware Office on WEXTL has 47 modules for building finance automations. Explore Lexware Office documentation for more.

Frequently asked questions

Common questions about automating Lexware Office in your workflows.

Lexware Office has 2 triggers, including "Watch Events" and "Watch Vouchers". Triggers are start points of the workflow, and automations may start from them.

Integration has 45 actions, including "Download a Bookkeeping File", "Download a Credit Note File", and "Download a Delivery Note File", and more. Refer to our Lexware Office Documentation for detailed inputs and outputs.

No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].

Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.

The Lexware Office integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Lexware Office official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

Absolutely. Where Lexware Office provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever Lexware Office or any other service sends event to webhook URL.

WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for Lexware Office inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with Lexware Office modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
