How to connect Lexoffice and AI GPT Router
Create a New Scenario to Connect Lexoffice and AI GPT Router
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a Lexoffice, triggered by another scenario, or executed manually (for testing purposes). In most cases, Lexoffice or AI GPT Router will be your first step. To do this, click "Choose an app," find Lexoffice or AI GPT Router, and select the appropriate trigger to start the scenario.

Add the Lexoffice Node
Select the Lexoffice node from the app selection panel on the right.
