thank you für your help

Is this the product you have? https://www.meineta.at/javax.faces.resource/downloads/ETA-RESTful-v1.2.pdf.xhtml?ln=default&v=0

Can you share the flow that you have created thus far (which returns 1802) with this forum> Please take care to format it properly so that it is displayed correctly.

The easiest way to do that is to click the 'Preformatted Text' button in the toolbar:

Then paste in your code or flow json.

You should end up with three back-tick characters - ````` - on their own line before and after the code.
